(which contains no music, only health, ammo, and money) Take a picture of Cohen after his death to unlock the "Irony" achevement,and gain the key to unlock his Music Box. After you do that, you can kill him at your convenience. Sander Cohen will ask you to take four pictures for him to complete his masterpiece. After just a few shots the Big Daddy will go down the count. When fighting a Big Daddy, use armor-piercing rounds (or explosive shotgun rounds), as they will deal considerable damage compared to regular rounds. How easy it that? All praises to the Killbot!

Now just walk around with your hypnotized Big Daddy in tow, and wait for another to appear and attack the new Big Daddy and your hypnotized Big Daddy will attack it to protect you. All you have to do is use the Hypnotize Big Daddy Plasmid on a Big Daddy so that he thinks you're a Little Sister and protects you. In order to do this, you need the Hypnotize Big Daddy Plasmid and the Natural Camouflage Tonic. If, however, you "harvest" no more than one little sister but "rescue" the others, you will get the good BioShock ending. If you choose to "harvest" more than one little sister, you will get the bad BioShock ending. Good Ending / Bad Ending There are two possible endings for BioShock that depend on how you treated little sisters throughout the game. See if the corpse doesn't kill them, the fire definitely will. First you find a corpse and by using Incinerate! set fire to the corpse, then by using Telekinesis pick the corpse up and whenever you see an enemy throw the burning corpse at the enemy. The easiest way to get kills on Bioshock is use the Plasmids Incinerate! and Telekinesis.
