Taken verbatim from the SA Games forum:
I just got PC Gamer’s June issue and apparently after previewing Prey, 3D Realms showed them a demo of Duke Nukem Forever showing “that DNF is up and running and in very fine form indeed.” According to Broussard, “Most of the weapons and creatures are done. Most of the levels exist, and there’s a ton of gameplay. We’re in the process of pulling it all together, and very much look forward to showing it off. It won’t be vaporware much longer.” The article talks about demos of interactions with the environments, saying they’re in the spirit of those in Duke Nukem 3D. They also report that DNF won’t be shown at E3 this year, and until there is a “delux unveiling,” nobody will get any more of a look at it.
Maybe it will get finished after all, I mean if George Broussard says it, they must be near finished.
The thread basically then turned into ‘yay DNF’/‘lol DNF is late’ posts for five pages on whether it was actually anywhere close to completion or not. Take this info with a grain of salt.
And here’s some stuff on Prey as well, the second-best vapourware in existence!
Prey! PDF FILE BEWARE!
