Bioshock: I Chose the Impossible

---

Description:Complete the game on Survivor difficulty without using a Vita-chamber
Trophy Level:Gold

---

Finish the game on Survivor. Switch Vita-Chambers to Off in the Options menu. Completing the game on Survivor will also unlock the trophies for Hard, as long as you dont use a Vita-Chamber. Some tips:

1. Save a lot. Save after every major fight. Save as often as you can.
2. DO NOT play another game save that is set to another difficulty. Doing this may not get you the trophy.
3. Take lots of pictures. Take pictures of everything.
4. Search everywhere for items. Take as much ammo and all the items you can carry.
5. Rescuing the Little Sisters gets you more Adam, which gets you more tonics and plasmids to use. Rescue all of them.
