BioShock - Fly Mode!
Fly Mode
Find and open "defuser.ini" in your BioShock installation folder. Find the key you want to bind the code to and set the bind (for example, "F10=fly").
Save the file and start the game, while in game press the bound key to toggle.
Note: The cheat can be deactivated if a video cutscene appears or if you move to a new area.
Now you can fly around Rapture like an underwater Pterodactyl... or something.
