See Max Plasmid Slots.

As you earn ADAM you will be able to buy upgrades and slots through a Gatherer's Garden. Once you progress and earn more ADAM, you will be able to upgrade your plasmids and buy new slots. The last slot is unmissable as it's a story related requirement.

You will need to find and use one of the "Power to the People" upgrade stations to add to your current weapon of choice. There are several located around Rapture, just walk up to one and press the to interact and select the weapon upgrade you want.

See All Weapon Upgrades

There are 14 stations located throughout the game. You will need to apply the various upgrades to all your weapons for this achievement. You can only apply one upgrade to a weapon at each station so you will need to find all 14 of them. Make sure you check all corners of each area as they are rather easy to miss.

See Master Hacker.

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

See Research Master.

See Research Master.

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

Splicer

• Brute Splicer
• Houdini Splicer
• Leadhead Splicer
• Spider Splicers
• Thuggish Splicer*

Security

• 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.

Link to 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.

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.

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.

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.

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)

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.

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.

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.

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.

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")

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.

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.

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.

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.

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.

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.

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.

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.

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.

This must be done in a Ranked Match.

The multiplayer levels are sections of Rapture taken from the first Bioschock game. Play at least one Ranked match on each of the follow levels and the achievement will unlock:

• Arcadia
• Farmer's Market
• Fort Frolic
• Hephaestus
• Home for the Poor
• Kashmir Restaurant
• Medical Pavilion
• Mercury Suites
• Neptune's Bounty
• Point Prometheus

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.

There are six new maps in the Rapture Metro DLC pack:

• Dionysus Park
• Fighting McDonagh's
• Fontaine Fisheries
• Pauper's Drop
• Siren Alley
• Smuggler's Hideout

At the moment, the DLC maps are included in the regular map rotation. This means if 1+ people in your lobby does not own the DLC, the new maps won't appear, and you will continue playing original maps. Everyone in your lobby must own the Rapture Metro DLC. A patch has been promised to fix the issue and introduce separate DLC playlists.

To unlock this achievement, you just have to play and complete a non-private match on each of the 6 maps once.

The Kill 'em Kindly game mode is included with the DLC, but can be downloaded separately by those without the DLC. However, your chances would probably be greater in this game mode in finding a lobby where everyone owns the DLC maps. You can try this, or any other game mode to get a win in each map.

You may want to save the headache and find a boosting group of those who own the DLC. That way you are guaranteed to play the new maps, and can trade wins.

Like Call of Duty's Prestige or Red Dead Redemption's Legend, Rebirth allows you to start over at Level 1. This can only be done if you own the Rapture Metro DLC. It is the only way you can get to Level 50 AND Rebirth (the Sinclair Solutions pack allows you to get to level 50, but not Rebirth). You get a special mask to show off your "bravery" but you lose almost everything; Plasmids, Tonics, Weapons, ADAM, and even your spot on the leaderboards! A patch is suppose address the leaderboards, but for now, be cautious when doing Rebirth unless you strictly want the achievement or don't care about your leaderboard rank.

See Trial By Fire for more information.

See Trial by Fire for more information.

At the end of a trial, whatever the score is, you will earn the stars you need.

• The first trial of every area gives you 1 star.
• The second trial gives you 2 stars.
• The last trial gives 3 stars.

As long as you complete the 18 trials the achievement is yours.

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.

You can view your trials from the gaming lobby. Completing a trial will reward you will extra ADAM to use towards your leveling.

The little sister can’t be touched if you want to gather 100% of the ADAM. Use as many traps as possible (Mini-Turrets, Trap Rivets, Proximity Mines, Trap Spear Ammo and Cyclone Traps) and always keep an eye on her. The easiest trial in which to gather 100% of the ADAM is the bonus trial in `The Adonis Baths`.

I personally gathered 100% of the ADAM in many other levels:

• The Adonis Baths – Trial 2
• Pauper’s Drop Market – Trial 2
• Simon Wales’ Church – Trial 2
• Folly of Dionysus – Trials 1, 2 and 3

Here are two different ways to get the achievement:

This is almost impossible to miss. You will have to gather at least 50% of the ADAM in every trial, which is very easy. This will come naturally while playing through the trials.

See Enemy of the Family for more information.

There are a total of 10 Vacuum Bots, five Vacuum Bots in Minerva's Den, and five Bots in Operations. DO NOT take the elevator to Operations if you have not destroyed all the five bots in Minerva’s Den, as there is NO way to come back to Minerva's Den. To be sure that you get everything, either follow this written guide right HERE, or watch the video below.

The Lancer is a new type of Big Daddy unique to the Minerva's Den DLC. The Lancer's main form of attack is its Ion Laser, which will provide constant damage for as long as you're caught in it. As well as that it also has another move called the Ion Flash, which will temporarily blind you if you see it. Despite all of this, he does not deal as much damage as the other types of Big Daddies, so if you can finish him off quickly, you will not suffer much damage from it. He also suffers from the same weaknesses the other Big Daddies do, so whatever strategy from armor-piercing rounds, to using security cameras against all work very well against Lancers. Security Bots can easily be found all throughout Minerva's Den, which can easily be hacked. They are an absolutely huge help against Lancers, as they are immune to it's Ion Flash.

Using the Gravity Well Plasmid that is also new to Minerva's Den, you can lock a Lancer in place. Doing so will prevent him from ever being able to from moving around and effectively using Ion Flash against you, which will make him much easier to take down.

Just like in the main game, you will encounter several Little Sisters throughout Minerva's Den. There are a total of six Little Sisters, three within Minerva's Den, and three within Operations. For the achievement, you must deal with all six of the Little Sisters found through the DLC. It doesn't matter whether you Save or Harvest all or some of them, so long as you deal with all of them.

If you still need to rescue a Sister, but she doesn’t appear anywhere on the map, walk around the area until you see a Lancer. Follow him to a ventilation hole where he will call a Little Sister, were you will then be able to rescue/harvest her.

Note: If you leave Minerva's Den or Operations and you haven't rescued/harvested the Sisters three Little Sisters here, you WON'T be able to come back!
