BioShock has gone gold and for those who plan to be a part of the Cult of the Rapture you’ll be happy to know the 1.3gb demo is now up on XBox Marketplace. I tried it out and wow, BioShock is going to be sweet as hell. The graphics are some of the best I’ve seen on next gen and the eerie surroundings guarantee a thrilling and chilling backdrop the dark story. Just wait till you see a Big Daddy destroy someone to see what’s in store for you. There’s also a new 60 second launch trailer that was just released to get you enticed to slap on some swim trunks and come below sea level.
