Walkthrough (PC)





Easy "Fully Researched Little Sister" achievement or trophy

 PlayStation3    Xbox 360  After you get the camera and the Hypnotize Big Daddy tonic, find a Big Daddy and follow him until he walks up to one of the wall vents. If you have not already saved or harvested the Little Sister, he will hit the wall and one will crawl out. Take as many pictures as you can until you cannot get any more research. Use Hypnotize Big Daddy. The Little Sister will crawl back into the vent. After Hypnotize wears off, the Big Daddy will hit the wall again, bringing out another Little Sister. Repeat the process.

Easy "Little Sister Savior" achievement or trophy

 PlayStation3    Xbox 360  Do not harvest a single Little Sister throughout the game. Tenebaum will reward you with gifts (including Adam) every time you rescue three Little Sisters. This proves more effective, as you get the same amount of Adam as you would if you harvested them but you also get the achievement or trophy.

Easy "Tonic Collector" achievement or trophy

 PlayStation3    Xbox 360  When buying Plasmids, Tonics, and Upgrades from the Gatherer's Garden, always buy the Tonics first. Then, make sure you search every area for other Tonics. When you reach Point Prometheus there will be three Tonics to find. The rest of the Tonics are available in the Gatherer's Garden. This will ensure you get the achievements. Note: To check how many Tonics you have, go to a Gene Bank and count each "track".

Easy "Brass Balls" and "Seriously Good At This" achievements or trophies

 PlayStation3    Xbox 360   Reach the end of the game under the Easy or Normal difficulty. Get Atlas down to his last jar of Adam. Pause game play, go to the "Options" menu and change the difficulty to "Hard". Defeat Atlas to unlock the achievements or trophies. Note: You cannot die while unlocking the "Brass Balls" achievement or trophy.

Half-Life reference

In the beginning when you first acquire the wrench, Atlas will first suggest the crowbar. This is the same starting weapon as the main character in Half-Life.

Pac Man reference

In the Arcadia level, you will find a place that appears to be a bar. Search around a bit and you will see a block of cheese, followed by holes. The cheese is cut like Pac-Man himself. There are holes next to it, none of which can be gun shots. If you shoot the floor with any weapon you have, the marks will not match.


Facing Sander Cohen twice

do not kill Cohen after completing his "masterpiece". When you go to the Olympus Heights and reach the area with multiple levels (not Fontaine's house for the poor) to get the second half of the antidote, visit one of the apartments on the first level (to your right upon entrance). This is Cohen's apartment. He tells you not the disturb the dancers. Just "knock over" the record player and deal with the upset duo. Cohen himself will then come down to kill you. He can be dispatched then. Go upstairs in his apartment (the door to your right upon entering his place), you will receive the achievement for entering his apartment and reach a Power To The People machine. Now, Sander Cohen will not stay dead. If you pickpocket his corpse, you will get his Muse key. When you get back on the Bathysphere, go to Fort Frolic. You can access the Muse (the chained up display) for some decent items, especially if you need first aid kits. Using your chemical thrower (and perhaps anything else) walk to the "masterpiece". Add Napalm and Criticism together and torch the awful thing. The area will turn red and Cohen will appear for round two. He is a little harder to kill this time and fights like a Houdini splicer. Pickpocket him again for the same items as last time (including the key for the already opened Muse). He is permanently dead.

Enemy ignores you

Just after receiving The ADOM extractor from the Little Sister, do not take the elevator to the last fight. Instead, go through the rooms you missed along the way. Cameras , turrets, Splicers, and Big Daddies will not see you, and electric trap bolts will not hurt you.
