Previously shown only to press behind closed doors, 2K has let slip nearly ten minutes of mind-blowing, vertigo-inducing gameplay footage from BioShock Infinite. You might want to have an air sickness bag at the ready.

This extended gameplay trailer is currently available on Xbox.com and through Xbox Live on your Xbox 360, but as reader Andrew points out, it's already all over YouTube and ready for mass consumption.

The game's hero, Booker DeWitt, seems to possess a great deal more character than the protagonists from previous BioShock titles, which should come in handy when dealing with the incredibly powerful (not to mention adorable) Elizabeth.

I'm just worried my fear of heights will keep me from making it through the game. Those roller-coaster hook travel segments nearly had my lunch painted across my computer monitors.
