After a preview session of the game Prey at the 3D Realms headquarters, the journalists of PC Gamer got to see a demonstration of Duke Nukem Forever (thanks: Trebster). George Broussard said "DNF is up and running and in very fine form indeed". The biggest part of the content is already finished, almost all of the weapons and creatures are done, so are the levels and there's a ton of gameplay. DNF will also feature a lot of interactivity with the enviroment according to the PC Gamer article. The release date is the same: when it's done.
