Nothing of the game has been made public for years until that Duke Nukem Forever teaser was released last December.
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.
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.
Lets hope the development of DNF won't take another ten years..
