Well, Bioshock PC DEMO. Go for it !
BioShock is a revolution in the shooter genre that will forever change
the expectations for the FPS. Going beyond "run and gun corridors,"
"monster-closet AIs" and static worlds, BioShock creates a living,
unique and unpredictable FPS experience. BioShock is the Shooter 2.0.
If you're going to buy the game this week, I highly recommend
you stay away from any forums that might have spoilers until you play the game
through. Our goal in making the game was to thrill and, often, surprise you.
Please don't ruin other people's experience by revealing secrets in unmarked
threads, and if you want to enjoy the game to its fullest, stay away from any
threads that might ruin the fun for you. With a game like BioShock, it will
really make a difference. [BioShock creative lead Ken Levine]
