In the third chapter of BioShock 2, you'll have to try to make it all the way through Ryan Amusements alive. The only way may be to watch this five-part series on completing the whole mission in the popular Xbox 360 video game.
Mahalo's BioShock 2 walkthrough is a great resource for staying alive through the gameplay of the video game on Xbox 360. This video covers all of the Ryan Amusements.
BioShock 2 description from its publisher 2K Games: "Set approximately 10 years after the events of the original BioShock, the halls of Rapture once again echo with sins of the past. Along the Atlantic coastline, a monster has been snatching little girls and bringing them back to the undersea city of Rapture. You are the very first Big Daddy as you travel through the decrepit and beautiful Fallen City, chasing an unseen foe in search of answers and your own survival."
BioShock 2 is available for the Xbox 360, PlayStation 3 and Microsoft Windows.
