Shacknews has been to 3D Realms' offices to actually, properly view Duke Nukem Forever, as you can see here.
We actually got to see the truth of Duke curator George Broussard's many past claims, including environmental puzzles and interactivity, a host of finished weapons, the existence of an in-game forklift, and plenty of heads and arms being blown off.
We both confidently agree that after seeing this demonstration, Duke Nukem Forever is looking great, and will easily stand apart from the crowd in both visual and gameplay styles.
You pretty much have to read that, so off you go. No release date as yet. We kill ourselves.
