Shacknews got to see Duke Nukem Forever in action and they seemed rather impressed given the somewhat lengthy development cycle the game has had:

However, that all changed recently. For a good half hour Shacknews witnessed several different DNF gameplay scenarios, mechanics, and environments being demonstrated.

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.

I wonder if the multiplayer could be cool. Coop would be nice :-)
