A Microsoft represntative told Joystiq at X08 in Toronto that Duke Nukem 3D, released on XBLA sometime in September, will have saved film and gameplay rewind features.
The rewind feature lets you do just that: rewind the game to a previous area where you messed up or simply think you can do things better. The save feature is self-explanatory too: take saved films from multiplayer matches and share them with your friends on XBL.
So there you go.
