Duke Nukem Forever Screenshots? Updated

Tramell Isaac's Blog now offers what the artist purports to be previously unreleased screenshots of Duke Nukem Forever, saying he worked on the first-person shooter sequel for two years and nine months before it was revealed that 3D Realms is apparently closing. There's little reason to doubt the veracity of Isaac's claim, as he is a long-time industry veteran whose credits include the first two Fallout games. The shots certainly look legitimate as well, showing off environments and a character, all with a high degree of polish. Thanks I.C.E. Update: There's some alleged DNF concept art featuring monsters and bewbies on Layne's Concept Art. Thanks Morris.
