We want your HALO 3 screenshots here. Add yours.
The Hushed Casket was founded in 2002 shortly after the launch of the XBOX console. Today the Hushed Casket is a thriving community of gamers, playing together and publishing news and stories that have appeared in major media properties like Newsweek, G4TV, USA Today, and Penny Arcade. Some game developers have even referenced our guides and news to support their gamers. We don't play Halo. We LAN Halo.

As I've said before Halo 3's
As I've said before Halo 3's newness is related to the campaign and the out-of-game experiences (from the user interface, to Theater, to integration with Bungie.net).
As for the multiplayer gameplay, it's not very different than Halo 2. It's as if Halo 3 were downloadable content for Halo 2 (if you can look past the graphics).
Perhaps 360 gamers are looking for a next-gen multiplayer game and are ditching Halo 3?
