The first BioShock Infinite footage to reach the public eye will be unleashed on Xbox Live next week, on September 21.
That's according to an Irrational Games rookie, who posted on the developer's official blog:
"My name is Chris Remo; as Irrational Games' newest employee, I've learned a lot about BioShock Infinite in the past several days.
"I'll be sharing some of that knowledge in the form of these short posts, one a day, as we approach the online unveiling of BioShock Infinite's first gameplay demonstration video, which will go live September 21 on Xbox LIVE and Xbox.com, and September 22 elsewhere online."
As revealed alongside a gorgeous trailer last month, BioShock: Infinite is the first in the series to be set above the clouds - and will be out in 2012.
