this is a program so u can play halo 1 on the internet. Its alot better than gamespy. If you play halo on gamespy, just delet gamespy, its horrible. There is alot more clans on xbc and alot more challenge on xbc.
www.xbconnect.com. Go there and DL the program. u will need a router and a cat5 cable to play though. Buts its loads of fun. You need to get on it.
