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.

Tried the cache clear code
Tried the cache clear code last night. A message popped up on my Xbox 360, "Do you want to run system maintenance on your Hard Drive?", I selected yes, and it ran for about 3 seconds, and said it was done. Hardly long enough to have really done anything, except perhaps scan for fragmented sectors on my HDD, but no noticeable "maintenance" was done. I was still unable to play COD4 on XBL w/out getting kicked from the lobby immediately once the game starts. Ran it again, and rebooted, just to make sure, still no success.
Best I can come up with, is that when I first booted COD4, and signed into XBL, it asked me if I wanted to install an update for it. I did, but that was back before 3G came out, and it took forever. W/ the slow and sketchy EDGE connection, perhaps the data it dwnld'd was corrupt.
