As promised 3D Realms have released the 3rd trailer for Duke Nukem Forever, a new teaser of the game in its current form. Download it locally from AusGamers in either 720p MOV
or 720p WMV
In true teaser form it doesn't show a great deal, but the footage on offer is purportedly in-engine. No new details as to a release date (haha) or platform have yet been mentioned.
