Duke Nukem Forever: New Screens
Blurry low-res screens, but screens nonetheless. Two of 'em, one showing Duke and some cavorting womenfolk, and the other some sort of tenta-beast thing. Duke4.net has 'em, acquired by one of their members by unlocking every achievement in the new (and reportedly excellent) Xbox Live Arcade port of Duke Nukem 3d.
Still not doing much to wow me - especially after that grrrrrrubish teaser trailer - but there is a bit of bottom on show, which someone will probably get excited about.
