Bioshock 2 takes you back into the underwater world of Rapture, but from a different point of view. This time around you will be playing as a Big Daddy, but not just any. You will be playing through the eyes of a Delta Series Big Daddy, the first and only Big Daddy of its kind.
The general garden variety Splicers have now transformed and became stronger over the 10 years since the first Bioshock. You may be stronger but the world of Rapture has changed so much over the past 10 years.
Several achievements have been reported to not unlock when the requirements are met. You can either try to complete the requirements again or try on another playthrough.
If your multiplayer achievements are also acting up keep re-attempting them until they unlock.
Another issue you may encounter involves the game freezing. There currently isn't a patch for these issues so make sure you have backup saves. Most freezing issues are related to multiplayer. A patch should be released shortly.
Before you start, carefully decide how you want to play though the game. There are quite a few achievements, which can be very easy to miss. It is possible to earn all the story achievements on one go but only if you know what to do.
Remember there is no way to backtrack and collect things you have missed. Once you leave a level and move onto the next you can't return.
Playthrough 1: (Easy/Normal)
The bulk of your achievements will be earned on your first playthrough of the game. Before you start read through the missable achievements above. With a little planning you should be able to earn most of your achievements on the first playthrough. Once you start the game turn off the Vita Chambers and aim to save all the Little Sisters.
Turning off your Vita Chambers isn't a requirement but it will stop you from using them by mistake.
+ Complete the game without dying (turn off Vita Chambers, save often)
+ Kill the Big Sister without dying
+ Kill three Big Daddies without dying
+ Save all the Little Sisters (and spare the outsiders)
+ Gather 600 ADAM with the Little Sisters
+ Find all 100 Audio Diaries
+ Find all upgrade stations (Apply all upgrades to your weapons)
+ Hack all machines (and 30 from a distance)
+ Kill 50 enemies with hacked Security (Bots & Turrets)
+ Upgrade at least one of your Plasmids fully
Some achievements require further explanation so read the guide for each achievement.
Playthrough 2: (Hard)
You may have decided to skip playing through the game on Easy or Normal and started on Hard. It is possible to run through the game on hard but it depends on how big of a challenge you desire. If this is your first and only playthrough review the information listed under playthrough 1.
If this is your second playthrough, you should only have to earn achievements you missed while on your first run.
Here are a few tips for playing on Hard:
+ Enable Vita Chambers
+ Collect weapon upgrades and use them on primary weapons
+ Hack security bots
+ Harvest Little Sisters for ADAM and less hassle.
+ Upgrade plasmids you use on a regular basis.
If you don't use certain weapons or Plasmids concentrate on them after you have upgraded your more commonly used items. You don't want to waste ADAM on skills you don't find as useful as others.
Little Sisters: ADAM Gathering
This time around ADAM plays a slightly different part in your character. You can interact with the Little Sisters and use them to gather ADAM for you. This is quite a lengthy process but provides its rewards. You can harvest from two bodies with one sister, but you need to be careful and make sure to protect the Little Sister as she collects for you.
If you want to make the most of the games achievements then you will need to gather ADAM with them and make sure you do not harvest them.
This process is rather straightforward but it's easy to miss out on researching enemies if you forget to use the camera. There are four levels of research to complete. Once you start to encounter new enemies it's best to research them fully as soon as you can. The stronger enemies are, the harder they will be to research. Start recording before you attack so you can take advantage of the extra research points. Also upgrading your research tonics is a must. Using multiple attacks and weapons will earn you more points.
If you can work out the right combination for your attacks while researching, you should be able to max out the research track with little to no effort.
Collectibles: Audio Diaries & Power to the People Stations
Much like the previous Bioshock most of the story is told through the audio diaries. You will need to collect 100 of them this time around but there are 128 in total. You may want to ignore these on alternative playthroughs but collecting them your first time around will save you the hassle of finding them all again.
Audio Diary/Power to the People Upgrade Station Guide
There are also upgrade stations located around the various levels of Rapture. Most are hidden from plain sight so be sure to check every room.
You will need to spend a fair amount of time leveling up and earning new skills within the multiplayer. There are also several achievements linked to various tasks, most are fairly straightforward but others may take time to earn.
Earning your 40th level will depend on your skill range and how well you cope against other players. You will need to earn 97000 ADAM before you hit this goal, so be prepared to put in the man hours. Most if not all the achievements can be earned within your first few games if you know what you want to achieve.
Rapture Metro Pack DLC
The Rapture Metro Pack is an all multiplayer DLC for Bioshock 2. It consists of 6 new maps, 2 new characters, 2 new masks, the 'rebirth' tonic (which will be discussed a bit later), increased level cap, and the new "Kill 'em Kindly" which allows you to beat down your friends, or foes, with a golf club. What's not to love? There are also 3 new achievements worth 150.
All of your achievements will be acquired through Multiplayer public matches. You can't earn them in private matches unfortunately. The new maps are as follows: Dionysus Park, Fighting McDonagh's, Fontaine's Fisheries, Pauper's Drop, Siren Alley, and the Smuggler's Hideout.
The only problem with attempting to get the two achievements for playing each map ("Aqua Incognita") and winning on each map ("Territorial") is that 2K decided (in their infinite wisdom) to add these to the regular playlist. So if you're in a group and 1 person does not have the DLC; you'll never see a DLC map. All people you are playing with must have the DLC map for these maps to be added to the normal map rotation. Upon completion of this tedious task you will earn the following two achievements.
Rebirth is the Bioshock equivalent of Prestige or Re-up. The original level cap was 40; with the addition of the Rapture Metro Pack the level cap was increased to 50. You must reach level 50 by whatever means necessary (boosting or playing); you have the option to be 'reborn' which means you start over from scratch. Your rank is reset to 1 and you become a newb again. Let's be honest though, the "Reincarnation" achievement will most likely be the last thing you do with this game. The option to be reborn will appear on the matchmaking lobby screen upon reaching level 50.
An unfortunate side effect of the rebirth was that it also reset your ADAM and world rank on the leaderboards. So if you care more about that than the achievement... don't be reborn.
It is possible to boost this game, although you need a minimum of 6 players. The best method of boosting is turret hacking; basically you and an enemy keep hacking the same turret back and forth for the entire round. Most maps have at least two turrets on them; there are a few that have three like Arcadia, and Mercury Suites. If you can't find a turret to take turns hacking on; you can hack vending machines albeit slower.
At the time of its release, this was a very doable set of achievements; I seriously doubt there is a very active community within the Bioshock 2 world. Online support has all but stopped as there are plenty of glitchers flying through walls and being all invincible and such. The success of your completion of this DLC hinges on finding people to play with that all have the DLC themselves. It all sounds like doom and gloom, but this was a great DLC with a great set of maps.
Protector Trials DLC
The protector trials DLC is a great way to get back into the game. In every trial, your goal is to defend the little sister and gather as much ADAM as you can.
There are 6 areas in the DLC:
- The Adonis Baths
- Atlantic Express Train Upkeep
- Pauper’s Drop Market
- Simon Wales’ Church
- Folly of Dionysus
- Persephone Cellblock F
Every area contains 3 trials plus a bonus trial (24 trials in total). You are equipped with different weapons and plasmids in every trial. This means that you have to find different techniques for each one. At the end of a trial, you will be rewarded with a letter: D, C, B, A or A+. Your result will depend on how much ADAM you have gathered. To get an A, you will need to gather between 85% and 100% of the ADAM.
You can use this Thread to help yourself if you are stuck in a trial.
Play through the 18 trials at your own rhythm. If your results are lower than an A, replay the trials until you get the needed score. Take your time and try to find the best methods to finish the trials. Remember that you can replay any trial at any time.
After the 18 trials, you will unlock the bonus trials. There are 6 in total (one on every map). They are the same except that you are equipped with every weapon available, fully upgraded, and you have access to EVERY plasmid.
NOTE: Be sure to change your plasmids at the Gene Bank before you start gathering! There are helpful plasmids like Summon Eleanor that can be used!
Minerva's Den DLC
Minerva's Den Wikia
Minerva's Den Achievement Guide
Minerva's Den is a single player installment for Bioshock 2 which is separate from the main storyline. Without going into too much detail and spoiling everything; you play as a Big Daddy and the main antagonist is a gentleman named "Wahl" who thinks he can predict the future because of a computer with the moniker of "The Thinker". Needless to say... splicing is a helluva drug.
You will spend approximately 5 hours traversing this campaign; four of the achievements are story related and can't be missed, while the final 4 are missable achievements. But with use of the roadmap and the guide you won't have an issue. Difficulty does not affect any achievement, so you can play on Easy if you wish. The higher the difficulty, the scarcer supplies become.
The story takes you to a new part of Rapture which is known as Minerva's Den. It's plenty dark, gloomy and wet like the rest of Rapture; it's also filled with Splicers that would love nothing more then to rip your face off. You will tussle with some familiar foes, along with a few new ones; Splicers and Big Daddy's alike. You can also gain access to a new weapon (Ion Laser), a new plasmid (Gravity Well) and two new gene tonics (Drill Dash, Master Protector).
You will earn four story related achievements as you delve deeper into Rapture; they are: "Login", "Root Access Granted", "Logout" and "SUDO".
Please note: there are Audio Logs scattered throughout Minerva's Den, but they are in no way attached to any achievements; they are more just for plot addition. HERE is a link to an audio guide walkthrough.
"Lancer Killer": This technically is missable (although highly unlikely) should you choose not to engage one. However, if you're going for the other achievements, "ADAM Addict" specifically, you will have to kill a Lancer. You will stumble across at least 6 of them during this campaign.
"Garbage Collection": This achievement requires you to destroy 10 vacuum bots during the campaign. There are 5 in Minerva's Den and 5 in Operations; should you move on to Operations without destroying the 5 bots in the Den, you will miss this achievement. HERE is a link to the walkthrough.
"ADAM Addict": You must rescue, or harvest, all the Little Sisters. Again, you must get them all in one area before moving on to the next. There are three Little Sisters in Minerva's Den and three in Operations; so six in total. If you are having trouble finding a Little Sister, as is similar to the main game, locate a Big Daddy and follow it to a vent where he'll 'call' a Little Sister.
"High Score": This is a mini game that can be found in Operations; you must get a high score of 9999 points with 4 lives. There's a terminal in an office upstairs that's a bit off the beaten path. It's basically a game of asteroids. Should you fail to reach the needed score you can try again. It's listed as missable due to you being able to miss the area; not that you only have one attempt at getting the score. Please refer to the guide for an accurate location.
This was a relatively short DLC addition to Bioshock 2, but it was entertaining with a decent plot line for what we'd expect out of Rapture. Assuming you follow the guide, you should have little issue with completing the DLC campaign whilst gaining all the achievements in one playthrough. Just be vigilant to check what you've done before you move on to another area that you can't return from.
The achievements aren't really too complicated but more time consuming than anything. With careful planning you can earn 1000 with minimal effort and enjoyment.
