Narrated by Bungie's Luke Smith, the video looks to be set in a Halo 3 (360) multiplayer map filled with AI bots, a feature the game currently doesn't support, and appears to show a full-fledged map creator at the end--suggesting that Halo 3 may be receiving additional features and functionality, most likely as downloadable content.

"Even though in Halo 3 you finished the fight, that doesn't necessarily mean that the ride's over," noted Smith. "Wait a second, there is no way we're showing this yet." [videofeature]http://www.youtube.com/watch?v=9ZCIdPfQqb8 [img]/extras/faylor/bungietease_1.jpg[/img][/videofeature]
