Update: The video has been taken off of Youtube, but for all of you who missed it the first time, here it is again.

Original story: Before today, the only people who had seen BioShock Infinite in action were a handful of lucky press members and those who attended Game Informer's cover story panel at Penny Arcade Expo. But today Irrational released a 10-minute gameplay video on Xbox Live. That demo has found its way onto YouTube and, subsequently, our site. Check it out below.
