Introduction:
This is a first person shooter that gives you powers in one hand, and guns in the other. You do not have to have played other Bioshock games in order to follow the story. The game does have stacking difficulties, so put in the code to unlock 1999 mode and start from there. I highly suggest you purchase the season pass (Season Pass Store in game menu) in order to get a really great head start as an equipment piece that is one of the best in the game. Make sure you are following one of the many collectible guides in order to gain everything. There is chapter replay, so you can always start somewhere. The items/weapons/money you had at the check point is what you start with, however. This is why Infused with Greatness is missable. Collecting the infusions will just reset when you go to the one you missed, therefore making you play the entire game from that point over again. This is why it's extremely important to get the Season Pass, so that you can miss a total of 5 and still be good. The check points seem far away from each other, so reload only when it will benefit you the most. You can reload check points shortly after gaining them to grind out kills with various weapons or to gain other types of achievements that require certain amounts If you quit without hitting a check point your progress will be lost. 

If you want to prepare, please visit THIS THREAD for useful links to help you out.

Playthrough 1999 Mode:
WARNING: During this mode, do not purchase anything from the Dollar Bill vending machines or you will have to play the entire game over again. These machines have ammo, salt, and health to purchase. You can enter them by accident, just do not purchase anything. If you do, reload your check point (hopefully that will work).
First things first, enter the button sequence           at the main menu to unlock the hardest difficulty. Now go purchase the Season Pass if you have not already. This is not required, but it will make things much easier for you. While this mode is the most difficult, it is not as bad as one might think. At first without powers and only a pistol, you will feel like the game is going to be extreme. Once you start getting certain equipment, powers, and upgrades, you will be able to do fine. Specifically, after gaining Elizabeth, you will be thrown ammo, Salts, and even money. 

Only upgrade the Carbine Rifle completely as well as Bucking Bronco and Charge once obtained. This will allow you to have all of your money available upon death. Once you die, you spend $100 to be revived. You can do other upgrades if you'd like. You may end the game with around $4,000 if you only upgraded what I suggested and died a few times here and there. If you read the description for 1999 Mode, I have given the perfect build to be extremely hard to kill and always have Salt/Ammo/Health. It's a melee build and it works beautifully. 

Also, as far as Infusion upgrades, be sure to put most of it into health. Shields break extremely easily and upgrading them doesn't give you much more of it.

Mop Up:
If for some reason you have failed at collecting everything or gaining certain achievements, go ahead and pick a chapter to reload and gain what you need. If you really enjoyed the game, start another playthrough on Easy to focus on what you have missed. After playing 1999 mode, you will find it laughable.

Clash in the Clouds DLC

This is a standalone DLC which means none of your progress, money, upgrades, etc shows up in it. You must earn money and complete waves to get all of your progress back. The good news is that you can keep farming the money by completing the same waves and challenges. You are automatically put on the hard difficulty and cannot change it. If you die in a wave you can just jump right back in, but you will fail the current challenge and forfeit leaderboard rankings (if that's even important to you).

Step 1: Complete all Waves
Go ahead and play through all the waves in each level. There are 15 waves in 4 levels, each wave having specific challenges. Complete the challenges when you can, but don't worry if you fail them. Once you have completed all the waves on all levels, you will have a lot of money to purchase upgrades and earn gear. This will allow you to attempt and concentrate on them later, when you're a whole lot tougher.

Step 2: Completing all Challenges
Once you are upgraded enough, you can try the challenges you do not have. To see the ones you have, look below the painting on each level. There will be a spot with the blue ribbons on it. You can tell what ones you have missed, because there won't be a ribbon there. They are in rows of 5. Go ahead and complete them, using a guide found in the Blue Ribbon Champ achievement details. This will likely take you a long time, as if you die or fail a challenge, you will have to start from the first wave again.

Step 3: Misc Achievements
There are only a few of these. Killing enemies with all weapons and vigors (except Bucking Bronco) should be easy if you keep track. Doing all combos and landing the kill should be easy after upgrading the vigors. For that you should see the achievement details for a list of the combos. You also must use undertow to knock an enemy off the map, catch him, then hit him again.

Step 4: Unlocking Gallery Items
As you complete all waves, unlock all ribbons, and collect all other misc achievements, you can focus on purchasing everything in the Gallery.

Burial at Sea, Episode 1 DLC

Episode 1 of the Burial At Sea DLC is fairly short. It can be completed in around 2 hours, depending on how much you want to explore. There are three story related achievements that will unlock just for completing the story.

The DLC introduces a new plasmid, Old Man Winter, and a powerful new weapon, the Radar Range. There are 2 achievements each for killing enemies using the new equipment. They're fairly easy to unlock through normal combat. There's also a few miscellaneous achievements, such as 'Confirmed Luddite' which is for destroying 10 turrets.

The short length combined with the ability to reload checkpoints/chapters make it hard to miss any of the achievements. The only part where you might have some difficulty is finding all the audio diaries. If you've gotten the voxophones in the main game, it's pretty much par for the course and you'll know what to expect. Be sure to save your money for "Fully Equipped". If you spend all your money on other upgrades and items, you might find yourself having to replay a bigger chunk of the game in order to earn enough money for the upgrades.

There is nothing related to difficulty, so set it to easy difficulty to breeze through it. Once you're done, look forward to seeing Episode 2!

Burial at Sea: Episode 2 DLC

Single-player campaign:
After a long wait, Episode 2 is finally here! In the depths of the glorious city of the sea, Bioshock Infinite: Burial at Sea Episode 2 is presented once again in Rapture. This picks up from Episode 1 where the player is now in the role of Elizabeth as she explores Rapture during it's fall.

The DLC introduces new weapons and equipment; the Crossbow, Lock Picks (to interact with and unlock doors and safes), and new Vigors; Peeping Tom (invisibility lets you see through walls as well) and Ironside (enemy shoots you, acts like a shield and fills up your ammo). The other Vigors are Possession (possess enemies) and Old Man Winter (freezes enemies or makes traps). There are collectibles again for Audio Diaries and Voxophones see "The Whole Story".

1998 mode:
Introducing a new mode combining stealth mode and hard mode together. This mode is to get people to play in a stealthier way. There is an achievement for the game in this mode called "Taffers Delight" which refers to the original Thief game which makes you play the story in stealth because your health is very low. Although this mode isn’t too challenging, it doesn’t give a whole lot of ammo or money. In this mode you only get the crossbow and plasmids. Finding different ways to take enemies out and saving crossbows when you needed is important. It is possible to go throughout the whole game not killing anyone. I suggest you play on Normal mode first to get the feel of the game and know where to go because in 1998 mode it does not tell you where to go; no for directions. See "Taffers Delight" for more details.

Conclusion:
All in all, the game is beautiful, fun, and has a deep story. The achievements are very nicely planned out. The only thing that could have been done better was collectible tracking and the ability to replay chapters with your current powers/upgrades. That or a true new game+ that let you carry over everything. Would have just been nice to upgrade everything to fully appreciate everything that the game had to offer.

BioShock Infinite Achievement Guide

Show completed achievements
Show secret achievements

There are 80 achievements with a total of 1695 points

  • Completed the game on Easy difficulty or above.

    See "Auld Lang Syne" achievement description.

  • Completed the game on Normal difficulty or above.

    See "Auld Lang Syne" achievement description.

  • Completed the game on Hard difficulty or above.

    See "Auld Lang Syne" achievement description.

  • Completed the game on 1999 mode.

    At the main menu, type in the code described in "Should Auld Acquaintance...". Start your game on this mode. It is the hardest mode in the game. Below is what to expect compared to 

    Cost to Respawn: $100
    Damage Taken: 200%
    Damage Dealt: 50%
    Shield Regen Delay: 6 Seconds
    Shield Regen Time: 4 Seconds

    Buying the season pass will make life much easier for you. This is because of the Electric Punch equipment it gives you. There is a 70% chance to stun a target for 4 seconds. You will be able to continue to melee an enemy until they are dead without any real worry. It works perfect against Motorized Patriots. Here is what you should aim to have.

    Fully Upgraded Weapon: Carbine 
    Fully Upgraded Vigor: Charge 
    Equipment: 

    • Electric Punch (or Electric Touch if no season pass): Gives 70% chance to stun an enemy for 4 seconds.
    • Blood to Salt: Enemies provide Salts upon death 40% of the time.
    • Vampire's Embrace: Melee kills give health.
    • Brittle-Skinned: Melee targets briefly vulnerable. Victims take 2x damage for 5 seconds

    Essentially, you will dominate pretty much everything. You get brief invulnerability on Charge attacks and it recharges your shield. It also adds explosive damage to the attacks. Once you have hit an enemy with Charge, start using melee on them. You will electrocute and stun them, then do 2x damage for 5 seconds. You will gain health upon their death as well as salts. As you hit them, they will continue to get stunned. One exception is Handymen and Sirens whom don't get stunned, so you will have to fight them with weapons as well.

    Yes, you do need the equipment. When you get to certain points where you get equipment, you can reload your checkpoints to pick them again. Sometimes this is not good as the checkpoints can be very far from where the equipment is. Remember that Handymen always drop equipment as well. When you get infusions, make sure to mostly upgrade your health first. Dying costs you $100.

    You'll pretty much need to only spend your money on upgrading Carbine, upgrading Charge and Bucking Bronco, and money spent on respawning. You should eventually have 30+ deaths as you are near the end. Make use of reloading checkpoints if you're dying more than a couple times against harder enemies like Sirens or Handymen.

    Below is a video of the above weapon/vigor/equipment build in action. I was playing on 1999 mode in this video, but it makes it look like I was playing on easy.

  • Unlocked 1999 mode.

    1) Beat the game on any difficulty.
    2) Enter the following button sequence           at the main menu.

    A prompt should appear saying it's been unlocked.

  • Killed 20 enemies with a Sky-Hook Execution.

    A Sky-Hook execution is a finishing move used by the melee weapon. After stunning an enemy by using melee with the , hold the  while they are stunned to execute them. This can only be done to lesser enemies and can be done as soon as you get the Sky-Hook. When you get Shock Jockey, you may also stun them with electricity first.

    You will notice when an enemy is low on health a skull appears above his head at this point approach him and hold  to perform an execution.

  • Killed 20 enemies with a Sky-Line Strike.

    While either on a hook or Sky-Line, you will have a button prompt to press  to do a Sky-Line Strike. You don't actually have to kill an enemy for the achievement to unlock, you just have to have pressed the button when prompted. An example in the below video shows that it can be done from hooks as well as farming the same enemy without actually needing the kill.

  • Killed 25 enemies with the Broadsider Pistol.

    This will be the first weapon you pick up in the game and most people will not use it again after obtaining the achievement unless there is no other weapons around. It can be useful when upgraded though.

  • Killed 25 enemies with the Paddywhacker Hand Cannon.

    Paddywhacker Hand Cannon
    A high damage pistol. It's almost a combination of the shotgun and broadsider pistol. It's quite effective after upgraded. Without the ability to increase clip or capacity, may find it hard to get consistent ammo.

    Bird's Eye Sniper Rifle

  • Killed 20 enemies with the Barnstormer RPG.

    Barnstormer RPG

    Vigors can be upgraded at the "veni vidi vigor" machines to make them more powerful thus making it easier to kill or afflict enemies.

  • Killed 75 enemies either with a Vigor or while the enemy is under the effects of a Vigor.

    Killing an enemy while they are under the effect would be like Bucking Bronco while they are in the air, or on fire from Devil's Kiss for example. See the "Well Rounded" achievement description to find out more details about the Vigors.

    You will add to this number in the course of getting trap kills, the 8 combinations, knocking enemies off columbia with undertow, and getting your falling kills. Zap and shoot is an easy method as from the first bioshock. Use Shock Jockey to zap them and then shoot them in the head for an easy kill.

    Murder of Crows, Bucking Bronco, and Shock Jockey should help greatly at netting you this achievement with combination gunfire kills.

  • Lured 3 enemies into a single Vigor trap 5 times.

    A Vigor Trap is the secondary function of a Vigor and uses 2x the amount of salt normally used.

    When you press and hold the button configured to use a Vigor ( or ), you will see a small timer animation. You may release the button  ( or ) at any time during this timer animation to successfully set a Vigor Trap.

    Set Vigor Traps wherever the enemy bottle necks, or is highly congested in a small area. Some easy spots to reload checkpoints are:

    -While in the Fraternal Order of the Raven for example, there is a group gathered below you of around 6. You can hurl a Devil's Kiss trap down and it will automatically trigger. You can keep reloading if you want.

    -Another good place is where there are Boys of Silence. Set a bunch of traps near an entry and make the Boy aware of you so that a bunch of enemies run at you. Stand behind the traps you set to let them trigger from the enemies.

  • Performed all 8 of the Vigor combinations.

    There are a total of 8 different combination moves the game has set for this achievement. While there are others, these are the specific ones being looked for. Sometimes it's easiest to set a trap (if available) of the two combo Vigors in the same spot.

    The 8 combos are:

    • Possession and Shock Jockey
    • Possession and Devil's Kiss
    • Devil's Kiss and Charge
    • Murder of Crows and Devil's Kiss
    • Murder of Crows and Shock Jockey
    • Bucking Bronco and Devil's Kiss
    • Bucking Bronco and Charge
    • Undertow and Shock Jockey
  • Killed 20 enemies using Possessed machines.

    Having the Possession for Less upgrade will help, but is not needed as you will have plenty of time to do this. You will find different machines you can possess throughout the game. These machines are as follows:

    • Gun Automation
    • Rocket Automation
    • Mosquito

    Possess them and if you want, aid by using other powers of means of distraction. The possession will not last very long at all or the enemies will destroy it quickly. If you find one that is near a checkpoint, you can continue to reload and keep using the same one. The progress will save it as long as you later get to a different checkpoint.

    Possession is the first vigor you acquire.

    NOTE: The Gun/Rocket Automation is the best one to possess in terms of time possessed and damage done. Followed closely by Mosquito. 

  • Opened 30 Tears.

    Opening 20 ally tears for Strange Bedfellows works toward this count of 30 opened tears.

    See Strange Bedfellows for more information. 

  • Killed 20 enemies using allies brought in through a Tear.

    There are 3 different allies you can bring through Tears that will help you get the kills needed.

    • Mosquito: Flying mini blimps with guns
    • Automated Turrets: Gun/Rocket turrets
    • Motorized Patriots: The robots who carry mini-guns

    These will become more frequent after saving Elizabeth. Hold  to create them and let them wreck havoc on your enemies. If you switch to a different tear, they will eventually be usable again. You can take cover and keep triggering them if you want to grind it out, or you can unlock the achievement as you play casually through the game.

    It may help to shoot enemies lightly before you use a summon tear so that the allies have easy targets to kill. allies include Mosquitoes, patriots, and automatons.

  • Killed 30 enemies while riding a Sky-Line.

    This can be achieved using weapons but not Vigors while riding a Sky-Line. To increase your chances of landing a successful shot, you can hold back on   as this will slow you down to give you better aim. You can also zoom while on a Sky-Line to make landing shots easier.

    If you are at a checkpoint before a Sky-Line and have the RPG equipped, you can grind out ills much easier as the RPG has splash damage and reloading checkpoints keeps your total running.

    Refer to "Bolt From the Blue" for more info on how to grind this using the headshot method.

  • Killed 5 enemies with a headshot while riding a Sky-Line.

    Riding on a Sky-Line, you will have to slow yourself down by pressing back on the  (or in whatever opposite direction you are facing). Using the Sniper or Carbine is best for headshots. Upgrading their damage will make this even easier.

    Use this in combination with the sniper rifle and you should have it in no time. a great spot for this is chapter 24: bullyard destroy the turrets then get your headshots, re-checkpoint if necessary.

  • Killed 10 enemies by utilizing environmental hazards.

    Environmental hazards are in various forms. The firework barrels are the first you find and can be shot. Use the Devil's Kiss power to ignite oil slicks for fire damage. Use Shock Jockey on puddles to cause electric damage. Bring Tesla Coils from a Tear to electrocute enemies. There are various ways to do this and you just have to utilize them when you see opportunity. Feel free to utilize checkpoints you get to grind these out when you find a decent spot.

     

    This can be farmed in the final battle, just in case you didn’t unlock it via natural playthrough. As long as you don’t do the final requirement (having to do with Zeplins) you’ll have unlimited enemies and oil slicks.

  • Killed 20 enemies by knocking them off Columbia.

    There are a few ways to make enemies get knocked off Columbia (when they fall off the world and die). They must have health as they fall, you cannot kill them because dead bodies will not count towards the stats. 

     When an enemy is near a ledge, use Bucking Bronco to lift them up. Not shoot them a few times as they float to knock them back a little bit. They should be hovering over the sky with no ground below them. Just wait for the effects of Bucking Bronco to cease.

     The absolute easiest way to knock them off is to press  and push them back over railings or ledges using Undertow. Enemies that are on barges will be prime targets as there is not much distance from ground to ledge and you can push multiple enemies off at once. 

    Great places for these are at the End of chapter 28, Factory, where you help Liz into a vent, and 38, Hangar Deck,whilst fighting in an airship.

  • Killed 5 enemies while they are falling.

    Use an upgraded undertow (upgraded helps in terms of time suspended in the air) and then use shock jockey. Lethal combination. May take a couple times.  Best place to try would be the same place in the above achievement (Factory location.)

    Alternatively: 

  • Killed 5 enemies while you are drunk.

    Drink a few bottles of alcohol and kill enemies while your screen is blurry. There are only a few opportunities for this achievement, usually involving a bar. 

    Perfect Opportunity
    The best area to get this is in Shantytown at the Graveyard Shift Bar. You can drink the alcohol and then start attacking people. They are not hostile until you fire first, which makes this a perfect place. You can just reload your checkpoint and be right in front of the bar again.

  • Killed 20 "Heavy Hitter" enemies.

    There are plenty of these enemies in the game. The following list are what the game considers a "Heavy Hitter".

    • Fireman 
    • Zealot 
    • Motorized Patriot 
    • Handyman 
    • Siren 

    You can also farm this on the final battle if you missed it through your playthrough.

  • Killed a Handyman by only shooting his heart.

    You must shoot a Handyman in certain part of his chest (his heart is in the center).

    You may unlock this naturally as you encounter the Handymen but a good place to unlock it is Plaza of Zeal, after visiting the Gun Shop for the first time

    Note: This takes place before "The Good Time Club", but the checkpoint will overwrite itself. If using chapter select, choose "Worker Induction Center", and go to the gun shop, trigger the story, and exit to go to this area. Also wearing a  dress attire to make you invincible after jumping off hooks/ skylines will help.

  • Equipped a piece of Gear in all four slots.

    There are 4 slots you need gear in. Hat, Shirt, Boots, Pants.
    Just find one of each and they will automatically equip for you if you press . You can change them in the menu if you want to change your gear (good for certain situations). If you purchased the season pass, you will get this achievement quickly, as it gives you a set of gear at the first bar you come across.

  • Fully upgraded one weapon and one Vigor.

    Weapons are upgraded through vending machines. The Minuteman's Armory will allow you to upgrade your weapons. The weapon has 4 upgrade slots, and a few of them even have the first unlock already in place. One of the best weapons in the game is the Carbine, so focus on upgrading that since you are limited on money (especially in 1999 mode). Vigors only have 2 upgrades and can be quite expensive. 

    The cheapest full weapon upgrade is the starting pistol.

    The cheapest Vigor to upgrade is Bucking Bronco.

  • Upgraded one attribute (Health, Shield, or Salts) to its maximum level.

    There are a total of 24 upgrades available in the game to collect. However, there are a total of 30 upgrade slows between health, shield, and salts. They are gained by collecting infusions (see "Infused with Greatness"). Each category can be upgraded to 10. Salts are the most powerful thing you can have in the game. Max this out first.

  • Collected every Infusion upgrade in a single game.

    There are a total of 25 Infusions that you can collect. 

    To make this easier refer to the following collectible guides:

    Maka's Collectable Guide

    IGN's Collectable Guide

  • Used all telescopes and Kinetoscopes in the game.

    Refer to "Infused with Greatness"

  • Used Elizabeth to pick 30 locks.

    There are a ton of locks to pick in this game. If you unlock a main door, then Elizabeth will use her hairpin. Otherwise, you will use lock picks. While they may seem rare at the start, you will eventually be picking up a lot of these. There are some cases where they will respawn when you go back and forth between areas. If you're worried about them, save them only for doors you know have collectibles behind them. You can always reload checkpoints to gain your picked locks.

    Lock picks are relatively rare and will be expended when Elizabeth picks a lock. Locks also cannot be picked while in combat. To perform a pick hit  and elizabeth will approach and pick the lock.

  • Collected every Voxophone.

    Refer to "Infused with Greatness"

  • Spent $10,000 at the vending machines of Columbia.

    You will get this when upgrading weapons and Vigors. If you reload a checkpoint, this will continue to count. You can grind this out with reloading this way. Just spend a few thousand in Vigors/Weapons vending machines then reload your checkpoint as long as there is one close by. 

    You get money for killing people, looting corpses, and containers. You will get this in the process of upgrading multiple vigors and weapons as well as buying items and ammo through play. It should unlock around halfway through the game.

    Note: Remember if you are on 1999 Mode, do not purchase from the Dollar Bill vending machines.

  • Looted 200 containers.

    As you progress through the game keep your eye open for containers to loot spare ammo, money, healing salts, and other goods. You should get this fairly early in the game if you are actively looking.

  • Completed the game in 1999 mode without purchasing anything from a Dollar Bill vending machine.

    The Dollar Bill vending machines are scattered throughout the game and sell items such as ammo, health, and salts. They are normally a refill station which you would use to help you along the way.

    DO NOT BUY ANYTHING FROM THESE MACHINES

    Note: Accessing or Possessing the Dollar Bill vending machine will NOT affect the achievement.

    Only Purchasing from the Dollar Bill vending machine WILL affect the achievement.

 

Secret achievements

DLC: Clash in the Clouds

There are 10 achievements with a total of 195 points

  • Defeat all waves in The OPS Zeal.

    Access the painting on the wall to defeat 15 waves in the area "The OPS Zeal" (by the motorized patriot). This area is given for free.

  • Defeat all waves in Duke and Dimwit Theater.

    Access the painting on the wall to defeat 15 waves in the area "Duke and Dimwit Theater" (by the motorized patriot). This area costs $200 to unlock. On wave 15, you must destroy the engine to end the wave. This is in the back most blimp that you fight enemies inside.

  • Defeat all waves in Raven's Dome.

    Access the painting on the wall to defeat 15 waves in the area "Raven's Dome" (by the motorized patriot). This area costs $500 to unlock.

  • Defeat all waves in Emporia Arcade.

    Access the painting on the wall to defeat 15 waves in the area "Emporia Arcade" (by the motorized patriot). This area costs $1000 to unlock.

  • In CitC, unlock all Gallery items.

    To access and unlock gallery items, when you start the DLC and are in the main area, look for The Columbian Archeological Society sign above some double doors. Go up to the various things in this room and see that it will cost money to unlock the items. You must keep playing the waves of enemies to continue to gain enough money to buy all of these unlockables.

    The total amount you will need for this achievement is $24,400.

  • In CitC, get a kill with each weapon and vigor (except Bucking Bronco).

    There are a total of 14 guns to use:

    • Pistol
    • Shotgun
    • Hand Cannon
    • Machine Gun
    • Sniper Rifle
    • Carbine
    • Repeater
    • Burstgun
    • Heater
    • Volley Gun
    • Hail Fire
    • RPG
    • Crank Gun (found on Motorized Patriot enemies only)
    • Skyhook (your melee attack)

    There are a total of 7 Vigors to use:

    • Possession
    • Shock Jockey
    • Murder of Crows
    • Return to Sender
    • Devil's Kiss
    • Charge
    • Undertow
  • In CitC, knock an enemy off the city with Undertow, then rescue him, then knock him off again.

    When you have the Undertow vigor, press to push an enemy away with water off an edge. Hold and let go to stop them from falling, then press it again to push again. This achievement seems glitchy in your favor. If you start up the first wave and just start using it even without an enemy being near a ledge, it can sometimes unlock. Be doing this to multiple enemies.

  • In CitC, use all eight different vigor combos to deliver the killing blow on an enemy.

    The combos are back again. The original game wanted you to do all of these for an achievement, now you must do them AND get a killing blow instead of just hitting an enemy with it. Do this after you have upgraded your vigors.
     

    1. Devil's Kiss & Murder of Crows: Use Murder of Crows on an enemy, and while distracted, shoot a Devi's Kiss at them.
    2. Devil's Kiss & Bucking Bronco: Use Bucking Bucking Bronco to lift an enemy in the air, and use Devil's Kiss to burn them.
    3. Devil's Kiss & Possession (Burning Possession): Possess an enemy and then use Devil's Kiss on them. While they are burning and possessed, they must get a kill.
    4. Devil's Kiss & Charge: While the target is burning from Devil's Kiss, use Charge on them.
    5. Shock Jockey & Undertow (Shocking Undertow): While the enemy is being electrocuted from Shock Jockey, use Undertow on them.
    6. Shock Jockey & Murder of Crows: In any order just use both Vigors on an enemy.
    7. Shock Jockey & Possession: Possess an enemy and then use Shock Jockey to electrocute them. While they are possessed and being electrocuted, they must get a kill on another enemy.
    8. Charge and Bucking Bronco (Bucking Charge): Use Bucking Bronco to put an enemy in the air, then Charge attack the floating enemy.

    Note: Equipping Burning Halo (gear) when you obtain it will help with the combos requiring Devil's Kiss. It acts as Devil's Kiss when you melee an enemy but deals much less damage.

  • In CitC, kill an enemy with splash damage by shooting a rocket out of the air.

    Only certain enemies carry the RPG weapon which shoots rockets. When you find these enemies, shoot them until they are very low on health. When you see the burst from the rocket launcher, try to shoot it in mid air. If done accurately, it will explode killing the enemy. You may have to try this a few times before you get it. Another way that may work for you, is shooting your own rocket and causing splash damage.
     

  • In CitC, complete all Blue Ribbon Challenges.

    There are 4 stages to complete 15 waves on. Each wave has a Blue Ribbon Challenge. When you start the wave, you can press to see what the challenge is. You are also shown before you start the wave. If you die, you fail the challenge automatically. The only way to complete the challenges is to get them done the first time. It is best if you wait until you have everything upgraded, therefore making this a lot easier. Focus on them and go back later. To see the ones you have completed, below the painting of the level there is a board with the ribbons you earned. It goes in a row as follows:

    Any missing ribbons you can easily tell what wave needs them and focus on it. It's also a good idea to buy a resurrection before the wave you are going to focus on. You do this from the door before the wave in the lobby.

    Refer to the guide below for more of a walkthrough and a list of all challenges for each level:

    Blue Ribbon Challenge Guide

DLC: Burial at Sea, Episode 1

There are 10 achievements with a total of 250 points

  • Collect all Audio Diaries in Burial at Sea - Episode 1.

    There are 17 audio dairies to collect in this DLC. They're not terribly hard to find. Where you might have trouble are the diaries behind doors that require lock picks to open. If you don't find enough lockpicks, you'll have to backtrack later.

    If you're the type to explore every nook and cranny, this shouldn't be too hard for you. Below is a complete video of audio log locations, along with locations of lock picks that you'll need for a handful of diaries.

    Don't worry too much about missing a couple. The DLC is fairly short, and you can reload previous chapters to claim any you've missed. You can check which ones you've already collected by hitting and cycling to audio logs.

    Be sure to take note of which ones you already have before reloading! When reloading chapters, any audio logs collected after that chapter reappear in the game and don't appear in your audio log history. You are still able to unlock the achievement by collecting only the ones you've missed.

  • Purchase any two upgrades for Old Man Winter or Radar Range in Burial at Sea - Episode 1.

    Old Man Winter upgrades are purchased at Gene Bank vending machines.

    • Winter Boost $125
    • Winter Mod $225

    Radar Range upgrades are purchased at El Ammo Bandito vending machines.

    • Accelerator Mod $150
    • Slow Cook Mod $200

    Purchase both upgrades for either the Old Man Winter plasmid, OR the Radar Range weapon to unlock this achievement. It costs $350 total for either one. You can actually unlock this achievement before obtaining either one because the upgrades are always available at the vending machines.

    I was able to unlock this just before getting the Old Man Winter plasmid, using the Gene Bank to the right of Jack Frost's Village. You can find an El Ammo Bandito vending machine right outside the area you get the Radar Range.

    Some tips for getting this achievement:

    • Explore and always be collecting as much money as you can.
    • Try not to spend any money on other upgrades until you've unlocked it.
    • Use possession on vending machines for extra money.
    • Dying has a cash penalty, so if it wasn't obvious, try not to die!
  • Destroy ten Turrets in Burial at Sea - Episode 1.

    Turrets are stationary objects with machine guns. They have a light that shows it's field of vision. The light turns red if it spots you and will start shooting at you.

    Destroy turrets by damaging them with weapons, plasmids, or a combination of both. This can be unlocked easily just playing through the game if you find and destroy most of the turrets.

    If for some reason you're having trouble, or missed it on a previous playthrough, you can reload the same checkpoint and destroy the same turret over and over and it will still count towards the achievement.

  • Make 5 enemies explode with the Radar Range in BioShock Infinite: Burial at Sea - Episode 1.

    See Chain Reaction.

  • Damage fifteen foes with an exploding enemy, using the Radar Range in Burial at Sea - Episode 1.

    The Radar Range is a new weapon in Infinite. It's found in the Housewares chapter after taking the tram. Through normal story progression, you will eventually enter a shop called The Bistro. When you're in The Bistro, part of your objective is in the basements kitchen area. It's also where you will find Audio Log #14: The Kiss.

    Here, you'll find a code locked door. Enter the code 3958 to unlock the door and collect the Radar Range inside.

    A group of 3 enemies will spawn behind you immediately after getting it. Aim at an enemy and hold down until the enemy turns completely red and explodes, damaging the other 2 enemies in the blast radius. This will count as 1 kill towards 'Cook and Serve' and 2 towards 'Chain Reaction'.

    From here, you can continue to play normally, and use it whenever you fight groups of enemies until you unlock it. You can also reload the checkpoint and repeat on the same group of enemies until they both unlock.

  • Shatter 5 enemies who have been frozen with Old Man Winter.

    Old Man Winter is a plasmid that's unlocked through the main storyline, so it's impossible to miss it.

    Once it's been unlocked, equip it and press to use it on your enemies. If your aim is good, the enemy will be frozen solid for a few short moments. The easiest way to do this is to get up close for the freeze, and quickly pressing for a melee attack to shatter enemy.

    Do this 5 times to unlock the achievement. You can reload the checkpoint, kill the same enemies, and they will still count towards the achievement. Purchasing both upgrades at a Gene Bank vending machine can make it easier, and would also unlock the 'Fully Equipped' achievement.

  • Freeze 2 enemies with the same Old Man Winter trap.

    Hold down to charge Old Man Winter. Release to set a trap. Aim for enemies that are grouped close together. Once the trap goes off and two or more enemies are frozen at the same time, the achievement will unlock.

    If you're having trouble, remember that you can reload the checkpoint checkpoints to try again on the same group of enemies.

DLC: Burial at Sea - Episode 2

There are 10 achievements with a total of 250 points

  • Collected all Audio Diaries and Voxophones in Burial at Sea – Episode 2.

    Click HERE for a complete guide on all collectibles with pictures by bs000.

    There are 25 Diaries and Voxophones to collect. Some are needed with a Lockpick to open doors you can buy them for $18 from vending machines if you save up or find them.

    Note: There is a side mission you must do for one of the Audio Diaries. It requires you to find FOUR code transmitters. It will open up a hidden room in Mantaray Lounge where you’ll have to turn the three wine bottles.

    - You can use the Peeping Tom plasmid to spot collectibles through walls, when you get the plasmid upgrade that allows you to use it without EVE when standing still.

    -If you missed some don’t worry you can go back into each chapter and select the ones you missed, even if you finished the main DLC story.

    Location: Cupid's Arrow
    Audio Log 1 - Laissez-Faire: The first one doesn't appear for awhile. Coming out of Ryan The Lion Preparatory Academy through the red EXIT sign, you'll see Cupid's Arrow shop to the left. Pry open the door and it's on a shelf on the left inside.

    Audio Log 2 - The Blue Dress: To the very right of the previous log is an employee’s only door requiring one lock pick. Inside is the next audio log, behind the dress on display. Don't forget to grab the Peeping Tom plasmid while you're here.

    Extra Note: After getting off the elevator a little later, you'll arrive at a large Bathyspheres Deluxe hub area. I suggest following the main quest straight to the Silver Fin Restaurant before exploring the other shops because some areas are inaccessible until you go there. There's less backtracking this way and the story brings you back anyway.

    Location: The Silver Fin Restaurant
    Audio Log 3 - Pennies on the Dollar: Once you reach the Lutece Device, turn around and jump over the counter into the kitchen area where you'll find this log on a desk.

    Audio Log 4 - Imprinting Roadblocks: Also in the area of the Lutece Device, find the stairs to the left of it. Once you're on top of the stairs, it's on the desk to the left.

    Location: Test-Drive
    Audio Log 5 - This Atlas Guy: Once you're finished in the restaurant and return to the Bathysphere Deluxe area, find the Test Drive shop. Go through the employee’s only door and find the log on a desk inside.

    Audio Log 7 - Old Man Winter Giveaway: From the previous diary, look under the stairs for another diary on the desk.

    Audio Log 8 - Prison Intel. Dispatch #8: And immediately after diary #7,go to the room where you pick up the Old Man Winter plasmid. Go to the room behind it and grab the diary from the body.

    Coded Transmission #1 - There is an optional side mission to collect four coded transmissions. You need to collect all four to gain access to a room later on that contains an audio log. This first transmission is near audio diary #8. In the room where you pick up the Old Man Winter plasmid, go to the room on the right and pick up the clipboard on the desk.

    Coded Transmission #2 - Exit the Test Drive shop, back to the Bathyspheres Deluxe area. Find the Information shop across from Test Drive. Find a clipboard on a desk in the back for this code.

    Coded Transmission #3 - Exit the Information area and find the shop with a Medicine From Your Pal Atlas banner above the door. Go inside and then through the door to your immediate left to find a clipboard on the counter.

    Location: Service Bay
    Audio Log 9 - Building the Impossible!: Eventually you'll find yourself inside the Service Bay area (which is also located in the Bathyspheres Deluxe hub) as part of the main quest where you look for a CO2 scrubber. Play until you get a short cutscene with Elizabeth talking about The Sting ray submersible.The Stingray is the red bathysphere near the top of the room. Straight across on the opposite end of this room is a locked door. You'll find a diary right on the other side of this door.

    Coded Transmission #4 - From diary #9, go to the first room on the right and find the clip board on the desk. You're now ready to complete this side mission when you go to the Mantaray Lounge later.

    Audio Log 10 - Hooligans: Return to the room where The Stingray is. Go to the locker room on the right and find this one in a sink there.

    Audio Log 11 - So Long, Suckers!: Still in the Stingray room, use your skyhook on one of the fixtures near the roof. An audio diary is in one of the white bathyspheres.

    Location: Mantaray Lounge
    Audio Log 12 - C'est La Vie: After getting the CO2 scrubber and returning to the Bathyspheres Deluxe hub, go to the Mantaray Lounge upstairs.When you get to the big yellow banner, pick up the diary from the body to the left on the floor.

    Audio Log 13 - Atlas Provides: Way in the back of the Mantaray Lounge is a locked door. Through the door is a plasmid mod and a diary at the bottom of steps.

    Audio Log 14 - You Stupid Bastard: Go back through the door you just unlocked and straight across from there you'll see 3 wine bottles in a row.This is what the coded transmissions were for. Turn all 3 bottles to gain access to this room and the diary inside.

    Location: Columbia
    Audio Log 15 - The Quality of Mercy: This is where the game transitions into voxophones. Play until you use a vent to get outside of The First Lady.There is a door to your immediate left. Go inside, go inside another door to the left for this voxophone.

    Audio Log 16 – Sacrifices (Lots of people miss this one): Turn around and go back outside. You'll see an airship straight across from you. Use your skyhook on the railing above you and dismount onto that airship. Find the voxophone inside.

    Audio Log 17 - Stay the Hand: Play until you find a giant cog symbol on the ground that says Efficient Workers on it. Inside the building right in front of it there's a desk with the next voxophone.

  • Gained five noisemakers through lockpicking.

    In the beginning of the game, you’ll be in front a lock at Silver Fin Restaurant. You’ll gain a noisemaker while unlocking doors and safes. A slider moves back and forth on the lock the blue tube is the one you want to hit for noisemaker bolts. DON’T hit the red tube it will trigger the alarm and once you hit it you can’t re-do it. You can reload the checkpoint after the door unlocks though in case you messed up. You can also get it later and buy or pickup more locks in the vending machines.

    If you missed it select the chapter 'Return to Rapture' and play until you get to the part where you first learn about noisemaker darts.

    Knocked out two or more enemies using the same Gas Bolt.

    You are first introduced to Gas Bolts laying on the floor in the Bathysphere workshop. You’ll have a chance to get this achievement with the gas bolts you obtain. Upon entering you'll hear a few splicers talking to each other. If you sneak around the corner, you should see three enemies clumped together, two sitting down and one standing up. You can stand up or crouch and shoot the gas bullet at the ground or on the splicers which should knock at least two out if not all. You only need two for this to register. If you missed this spot you can go back and try it in the hub when you get a gas bullet save it for later when you see two enemies bunched together or you can reload the chapter.

  • Used Ironsides to collect 20 rounds of ammo or more in Burial at Sea – Episode 2.

    Ironsides is a plasmid that lets you steal bullets from an enemy's gun while they fire and it inserts into your gun (like Borderlands 2 with the Shield that eats bullets). Getting the Ironside will be after you find all the requirements for Suchong’s Research. See "Up and Running" for more information.

    If you missed this achievement the first time you can always reload the chapter 'Return to Rapture'. Hold when enemies fire at you.

    NOTE: The function to this plasmid doesn’t work that well sometimes they will fire at you and it doesn’t register right or they won’t fire and you waste your eve.

    The Police Academy is a good place to farm this achievement where you first get hit by a turret there is a vending machine close for more Salts. Use Ironsides on the turret or enemies works for both, and then keep reloading the checkpoint until you have it. In 1998 mode or Normal mode make sure you aren't full on ammo for your equipped weapon as you can't gain any more.

  • On three occasions, knocked out an enemy after silently dropping off a Freight Hook.

    This achievement can be done in the Service Bay Hub area, Manta Ray, or Suchong’s Lab anywhere that has a freight hook. When you hover over the hook above, press , but be careful you are only are on that hook for a limited of time it will start making noise and scares the enemy. Press to drop behind an enemy but remember to hit as soon as you land to quietly land. Press quickly to use your Hook melee to knock them out.

    You only need to do this three times and its very easy. If another enemy see’s you run away, hide out and try it again. The counter still registered a previous successful hit after a reload of the checkpoint so don't worry about dying.

  • While invisible, used Peeping Tom to knock out 15 enemies with a melee attack.

    First you have to obtain Peeping Tom. As soon as you get the objective "Go To The Silver Fin Restaurant" and before entering the elevator, go to the left broken door with a sign above "Cupid's Arrow" and lift it. Inside you'll find it.

    From there on, hold (to go invisible) and as soon as you approach any enemy hit them with while still holding .

    If you should run out of EVE you can buy it for $20 at the vending machines.

    There is also an achievement tracker in the game but it will only update very 5-10 knock outs. So keep that in mind!

    Upgrade #1: If you find the "PEEPING CLOAK MOD", it removes EVE cost for invisibility while standing still. This is found in a room next to the Manta Ray Lounge!

    Upgrade #2: "PEEPING VISION MOD" - Can be found in a side-office (locker area) of the main room where you find the CO2 Scrubber Replacement, right where you can enter/exit the lower passage. It removes EVE cost for seeing through walls while standing still.

    Note: If you reach a checkpoint (upper right screen) and you are low on EVE, simply reload it and you should have full EVE again. That was on EASY difficulty though! - credit to JuSt BLaZe

Secret achievements

  • Repaired the machine in Suchong’s lab in Burial at Sea – Episode 2.

    This is story related and can’t be missed.

    Following items needed to repair the machine in Suchong’s Lab:

    • CO2 Scrubber: in the Bathyspheres Deluxe hub. Pull the Lever to bring down the Bathysphere.
    • Heat Sink /Old Man Winter’s Plasmid: in Test Drive. You’ll need to talk to a guy behind a door he’ll let you in to get the Plasmid but only during the quest to pick it up.
    • Cathode Tube: Found in any Vending Machines.

    Bring back all three and install it on the Transmitter in Suchong's Lab so you can use the Tear.

  • Delivered the hair sample in Burial at Sea – Episode 2.

    This is story related can’t be missed.

    Once you’ve gone through the tear after collecting the parts for the tear machine, you will be in Columbia. A few enemies will be in the next couple of areas to take out; you can work on getting "Glutton for Punishment" here. There will be a turret in one of the areas you need to take it out after taking this out you will go either on the left or the right to go outside on ramp to a skyboat to grapple on a skyhook then getting off on the other side and follow through to Suchongs Lab you will notice his research and discovery. Along the way after you’ve watched a short video you will notice a desk behind you that has a song bird plush and the hair sample that is glowing yellow pick it up to unlock the achievement.

  • Completed Burial at Sea – Episode 2.

    This is story related can’t be missed.

    This achievement will unlock during the credits. You can get this on Easy, Normal, Hard, 1999 or 1998 new stealth mode.

  • Completed Burial at Sea – Episode 2 in 1998 mode.

    1998 mode – New mode that makes the player play stealthy. You don’t have to play stealthy but you should since your enemies have quite a bit of health and you basically have none. Though you get medical bags they act for replenishment like in the first and second Bioshock.

    In this mode there are a couple things different than Normal or 1999 mode:

    • You only get Crossbows three gas bolts, four tranquilizer bolts, and five alarm bolts maximum capacity (no pistols or shotguns).
    • No use of the .
    • Health is very low; one shot and your health is pretty much gone.
    • Not much ammo for crossbows, running out of EVE quickly.
    • You only stun fire and ice Splicers for a short while you can use to knock them out after; they can get one-shotted from Gas Bolts so save those.
    • Certain actions will give away your position and draw enemies to your attention, so be aware of these three things: Walking through any puddle or stream of water, broken glass, even while crouched. Walk around them if you can. Hanging onto Skyhooks for too long will make noise.
    • It’s not like 1999 mode you don’t have to pay any money you don’t die either if you get caught by someone right away you’ll be very hurt if they shoot at you.
    • Armored enemies can’t be substituted with a melee, use a tranquilizer or Possession if needed.Like all stealth type games take your time with 1998 mode. Plasmids to use are Peeping Tom and Possession. Try to avoid enemies using vents and your surroundings skyhooks and railing if needed. You’ll probably want to crouch through most of the game and become very sneaky. You can also bait enemies try and make some noise and crouch behind something and use Peeping Tom and then knockout melee them. Vents are pretty useful as well but looking for them without Peeping Tom could be hard. You don’t have a whole lot of money so save it for Health Bags $25, Cigarette sare pretty cheap $3 but they take away your health and Full Salts are $20. Only buy ammo if you truly need it. Just sneak around and knock people out to save on ammo. You could play the game without ever killing anyone.

    Best way for the fight for 'Return to Rapture' ambush in Suchong's lab is hiding in the locked door with the Turret and Old Man Winter Upgrade. This provides you a lot of cover and it forces enemies to attack you from a single vantage point. How you deal with them is up to you. Melee when you can, and use tranquilizer bolts when you have to. You'll face approximately two Fire Splicers and six or more regular enemies, so don't leave the room until Elizabeth taunts Ryan that she won the fight.

    After you have survived an ambush, go outside to the Silver Fin restaurant and turn invisible. You’ll need to get it to save so I’d suggest going into another store and try to get it to auto save. You can sneak by them using Peeping Tom if you want. There are more Fire Splicers coming up in the next area be prepared stock up a little if you can.

    In the Mantaray Lounge is probably the hardest part of the game use noisemakers for distractions, overwhelming with enemies use Peeping Tom to get away while invisible, burn health packs, anything else you can use for tatic to get to the elevator because this the the last real and probably the only killing you will do. If needed, after killing someone run back and get an autosave just in case it's a pain to redo it all over again if you die. The skyhook for some reason is disabled in this area and the vents leading to the room with water. Use the room with the water in it to lure enemies to you if it's unlocked for you. If not try to lure them upstairs. There is a medical bag if you need it in the room with the water and a vending machine. Careful of the turrets up the stairs. Go through the elevator and the achievement will unlock during the credits.
