Prolific Hacker20

See Master Hacker

Master Hacker20
Hack 30 machines at a distance with the Hack Tool.    

The hack tool can be quite useful if you need to hack a turret or security camera without being detected. You can also use it to hack and lower prices on vending machines. You will find the hack tool early on so start hacking when you're able to.

Once you start hacking a meter will pop up on the screen with a needle which bobs back and forth, press on the green or blue areas to progress in the hacking. If you hit the blue lines you will be rewarded, green lines will progress and blank spaces will shock you.

There are eight machines which need to be hacked:

  • Circus of Value
  • Door Locks
  • El Ammo Bandito
  • First Aid stations
  • Safes
  • Security Bots
  • Security Cameras
  • Security Turrets
First Research5
Research a Splicer with the Research Camera.    

See Research Master

One Research Track20
Max out one Research Track.    

See Research Master

Research Master20
Max out research on all 9 research subjects.    
Once you acquire the camera you will be able to research your enemies. Doing this will earn extra skills to use against your enemies. There are four research levels for each enemy. Use multiple weapons and Plasmids together so your score meter goes up. If you keep using the same combination to kill the same type of enemy your score will not be as great.

Big Daddy/Sister
  • Big Daddy - Alpha Series
  • Big Daddies - Bouncer - Rosie - Rumbler
  • Big Sister
  • Brute Splicer
  • Houdini Splicer
  • Leadhead Splicer
  • Spider Splicers
  • Thuggish Splicer*
  • Security Bots - Security Cameras - Turrets

*Once you find the camera start researching straight away. Thuggish Splicers don't appear in the later levels so make sure you research them before you leave Pauper's Drop.

Researchers Handbook

This guide will provide all the locations and all the basic information you need to know about researching.

Note: You can keep track of your research by pressing and viewing the research tab. Doing this will help you keep track of what research you have done, and what research you need to do.


Grand Daddy25
Defeat 3 Big Daddies without dying during the fight.    
If you're starting out on easy this shouldn't be an issue. You need to fight three Big Daddies without dying. You can use Security Bots, Turrets or hypnotize Splicers to help you take down a Big Daddy. Once you have taken down one Big Daddy save your game and move onto the next. If you are playing with the Vita Chambers off you shouldn't have to worry about re-spawning by mistake.

If you are attempting this on hard you may have a tough time taking down a single Big Daddy. Make sure you have plenty of Health and EVE, using Winter Blast with the Drill seems to be the most effective way to kill a Big Daddy. Continuously freeze him while you attack.
Master Gatherer30
Gather 600 ADAM with Little Sisters.    
Once you adopt a Little Sister you can set her down next to glowing bodies to collect ADAM. A Little Sister can gather 40 ADAM from each body or 60 ADAM using the "Proud Parent" tonic.

Basic Gathering
As you start out you will need to harvest two bodies with each sister until you earn the "Proud Parent" Tonic.

8 Sisters with 2 bodies = 80 ADAM, 80x8=640

Proud Parent Tonic
You will be rewarded with this tonic after saving four Little Sisters. This will allow you to collect 60 ADAM per body rather than the previous 40 ADAM. If you harvest your sisters after gathering you may miss out on this tonic.

5 Sisters with 2 bodies = 120 ADAM, 120 x5 = 600

Depending on if you use the tonic or not you will earn this achievement either before or around Dionysus Park.

You can either use your map to find the ADAM or you can hold down the for a second and a trail will appear. This will lead to you the bodies that can be harvested.

Note: Saving/Harvesting a Little Sister does not count as a gather. Make sure you gather with each sister twice to avoid missing out on this achievement.
Fully Upgraded a Plasmid10
Fully upgrade one of your Plasmids to the level 3 version at a Gatherer's Garden.    
Each Plasmid has three levels which can be bought form a Gatherer's Garden or found. You can't backtrack so make sure that you collect as many Plasmids as possible. Buy any of these level three upgrades and the achievement will unlock.
All Plasmids20
Find or purchase all 11 basic Plasmid types.    
It's fairly hard to miss a Plasmid bottle because they are brightly coloured. You will either be given them as a gift or have to buy them from a Gatherer's Garden. You only need to own one level for each Plasmid, buying all three levels of a single Plasmid will not count for this achievement.

These are the earliest known locations to find each Plasmid. You can buy or find them in later levels also.
  • Cyclone Trap (Bought, Pauper's Drop)
  • Decoy (Bought, Pauper's Drop)
  • Electro Bolt (Gift, Adonis Luxury Resort)
  • Hypnotize (Gift, Pauper's Drop)
  • Incinerate! (Bought, Ryan Amusements)
  • Insect Swarm (Bought, Siren Alley)
  • Scout (Bought, Siren Alley)
  • Security Command (Gift, Siren Alley)
  • Summon Eleanor (Gift, Persephone)
  • Telekinesis (Gift, Atlantic Express Depot)
  • Winter Blast (Bought, Pauper's Drop)


Trap Master15
Kill 30 enemies using only Traps.    
This may sound quite time consuming but can be done with an alternative ammo for the rivet gun. Early on you will will find Trap Rivets for your gun. Press with the Rivet Gun selected to equip this ammo type, once selected you can either fire them directly at your enemies or set traps.

If you want to take the more creative approach you can mix your Plasmids to form traps. Mixing Cyclone with Incinerate/Elctro Bolt also works rather effectively.
Master Protector15
Get through a Gather with no damage and no one getting to the Little Sister.    (4) 

This maybe be a little difficult until you find the right spot. While making your way through Ryan Amusements and enter "Journey to the Surface", you will have to harvest ADAM from a body in a open room. You can hack the turret and place Rivet Traps on the floor and around the doorways. Once you have everything setup, place the sister down to collect ADAM. You can now back up into the corner and pick off splicers as they flood the room.

As long as you watch out for any splicers with guns and let the turret do all the work you should earn this without any issues.


Big Spender15
Spend 2000 dollars at Vending Machines.    
This should come with natural progression in the game, loot anything and everything to find useful items. Half of what you loot will be money, once you find a vending machine either buy ammo, health or anything else you need. Just keep repeating this process until you have spent over 2000 dollars on vending machine items.
Dealt with Every Little Sister50
Either Harvest or Save every Little Sister in the game.    
You will encounter the Little Sisters who will help you through the game, if you let them. Decide which route you want to take and stick to it. Saving every Little Sister will be more rewarding but Harvesting will gain you more ADAM.

If you decide to Harvest the sisters you will miss out on the Savior and Master Gatherer achievements. You will be given three options with the Little Sisters you encounter, Adopt, Harvest and Save. Adopting will allow you to harvest bodies for ADAM which will go towards Master Gatherer. Once you are finished gathering with your current Little Sister, take her to a vent and save her. You can gather two bodies with one Little Sister. You won't be rewarded so well in the beginning, but using a Little Sister effectively will reward you in the long run.

You can keep track of how many Little Sisters you need to save by pressing , and viewing the stats at the bottom of the pause menu.
  • 0 - Adonis Luxury Resort
  • 0 - Atlantic Express Depot
  • 1 - Ryan Amusements
  • 2 - Pauper's Drop
  • 3 - Siren Alley
  • 3 - Dionysus Park
  • 3 - Fontaine Futuristics
  • 0 - Persephone
  • 0 - Inner Persephone

Note: Do not leave an area and progreed to the next without gathering and dealing with the sisters. If you do so you won't be able to return. Gathering does not count towards dealing with each sister. You must either Save or Harvest all the sisters for this achievement.


Against All Odds30
Finish the game on the hardest difficulty level.     
Finishing the game on the hardest difficulty may be easier for some than others. If you are a fairly experienced with First Person Shooting games you shouldn't have too many issues, but here are a few tips:
  • Take cover
  • Use first aid sooner rather than later
  • Don't be brave, run away if you are overwhelmed
  • Use Vita Chambers (unless you are going for "Big Brass Balls")


Big Brass Balls25
Finish the game without using Vita-Chambers.    
If you have played the first Bioshock you may have attempted this achievement. Unlike the first you can complete the game on any difficulty but you must not use the Vita-Chambers. Start on easy or normal and make your way through the game.

Take your time and avoid as much unnecessary conflict as possible. If you are overwhelmed either take cover or run away and use your health kits when needed.

Note: Once you start the game you can turn the Vita-Chambers off through the option menu. Doing this will stop you from making a mistake and using the chambers. Make sure you save on a regular basis.
Rapture Historian40
Find 100 audio diaries.     (1) 
You will find audio diaries through each section of Rapture. They provide a lot of back story and depth to characters that you might run into while exploring. Make sure to check every room you enter for these diaries.

There are 128 audio diaries throughout Rapture so missing a few isn't an issue, but don't just ignore them. You won't be able to come back and collect them once you move onto the next level.

Audio Diary/Power to the People Upgrade Station Guide
Unnatural Selection10
Score your first kill in a non-private match.   
This must be done in a Ranked Match.

You should be able to score at least one kill in any match you take part in. If you are having difficulty taking down other players use your Plasmids while shooting.
Welcome to Rapture10
Complete your first non-private match.   
Load up any ranked game and play through to the end. Once the game is over and you have completed the full match the achievement will unlock. If your host quits or you are disconnected you won't be rewarded for completing the level.
Disgusting Frankenstein10
Become a Big Daddy for the first time in a non-private match.   

This must be done in a Ranked Match.

While running around the areas of Rapture you will see an announcement at the bottom of the screen. "A Big Daddy suit has spawned near your location", make your way to the suit if you know where it is and press to wear it.

Normally this turns into a mad scramble between players to get the suit. If you do see the suit laying on the ground grab it before someone else does.

You can use any game mode other than Capture the Sister as players will spawn as the Big Daddy.

"Mr. Bubbles-- No!"20
Take down your first Big Daddy in a non-private match.   
This must be done in a Ranked Match.

At some point in the game a Big Daddy suit will spawn randomly in the level. Someone will pick up the suit and go on a kill rampage. The most effective way to take down someone wearing the suit is to use Incinerate! or Winter Blast and the shotgun or machine gun.

You don't need to waste all of the players health but you do need to be the player to perform the final blow. If someone else fires the final shot you won't be rewarded.
Mother Goose20
Save your first Little Sister in a non-private match.   
This must be done in a Ranked Match.

While playing Capture the Sister, you will need to capture the sister while playing on the offense and return her to the vent. This will take some patience but using the Aero Dash Plasmid will give you an advantage. You will earn this Plasmid at rank 4.
Two-Bit Heroics10
Complete your first trial in a non-private match.   
This must be done in a Ranked Match.

Complete one of the sub objectives required to earn extra ADAM. Some of these tasks are fairly straightforward, where as others will require you to complete harder tasks.

Proving Grounds20
Win your first non-private match.   
Join any Ranked game-play you feel comfortable playing and either be the overall winner or on the winning team.

Note: This should come natrually but only seems to unlock for most people while playing team games.
Man About Town10
Play at least one non-private match on each multiplayer map.   
This must be done in a Ranked Match.

  • Fort Frolic
  • Hephaestus
  • Home for the Poor
  • Kashmir Restaurant
  • Medical Pavilion
  • Mercury Suites
  • Neptune's Bounty

The levels are randomly selected so it may take a little while for you to play on each level. If you are working towards "Choose the Impossible" you should have played on each level at least once by the time you get to level 40.

Note: If the host disconnects or you quit out, you won't be credited for completing the map.

This is a rather odd achievement and very easy to miss if you don't know what to look for.


Distance Hacker5
Used the Hack Tool to hack an object at a distance.    

This can't be missed as you will need to hack a door to progress early on.

See Master Hacker

Defended yourself against the Big Sister without dying.    

The Big Sister will challenge you on the harder difficulties but she shouldn't cause you too many issues on easy. Keep moving and use your Plasmids with heavy or armor piercing rounds.

You will run into the Big Sister on a regular basis throughout the game, but you will only have a few chances to do this achievement.


Look at You, Hacker15
Killed 50 enemies using only hacked Security.    
While hacking various machines for Master Hacker you will need to hack the security bots and turrets. Hack one of these robots and allow them to kill for you. A little patience is required as you will have to let the security bots kill your enemies.

Using security Plasmids or Security Cameras doesn't count towards the achievement. You need to directly hack a turret or bot for your kills to count.

If you are having issue finding bots and turrets allow the security cameras to raise the alarm so you can hack the bots.
Adopted a Little Sister5
Adopted a new Little Sister for the first time.    
This is story related and can't be missed.

When you encounter the first little sister choose to adopt her by pressing . If you are working towards the other Little Sister achievements make sure not to Harvest any sisters.

See Savior
Saved every Little Sister and spared Grace, Stanley and Gil.    
Once you save all the Little Sisters and spare the lives of Grace, Stanley and Gil the achievement will unlock. If you have decided to harvest any Little Sisters or to kill any of the characters you will need to start over.

Grace Holloway - Stanley Poole - Gil Alexander
You will run into these characters as you make your way through the game. They will hinder you as you try to progress through the levels. Once you have completed whatever tasks you need to, you have the decision to kill them. Make sure you don't kill them either through requests or your own decision.
Killed an enemy with its own projectile.    

Using telekinesis grab a thrown projectile and throw it back at the enemy. You can either do this against a Splicer or any other enemy which throw projectiles such as grenades or rockets.

One of the easier ways to earn this achievement is to kill a Rumbler with it's own rockets. You can stand in front of them and keep using telekinesis over-and-over until you kill the Big Daddy. Splicers randomly throw grenades, but the Rumbler will always fire rockets at you if you are at a distance.

This can also be done with Thuggish Splicers and Rocket Turrets.
