A nearly three-minute-long clip from the presumably never-to-be-released Duke Nukem Forever has emerged from former 3D Realms animator Bryan Brewer.Released to the public as part of Brewer’s online portfolio, the clip takes us through a number of different parts of the game — a game that, though much derided, actually looks like a fun time here, and certainly a worthy heir to Duke Nukem 3D .It’s just too bad that 3D Realms fell apart and probably doomed this game to languish as a minor historical footnote.Duke Nukem Forever Gameplay Footage Leaked
