Shacknews has got its hands on what may or may not be some screens from Wolfenstein multiplayer levels.
There's a ton of stuff through there, all watermarked. They look a bit... early.
Activision's having none of it: "The screens in question were not distributed by Activision or approved by Activision, and thus Activision cannot confirm their authenticity."
It's out this year, real or not.
