Ignore the last answer that was on here. Bungie is NOT making a Halo 4. The only game they released info on us is Halo 3: ODST. Halo is a TRILOGY. They'll make another trilogy more than likely, that revolves around MC and Cortana and their encounters on the planet they were headed towards at the end of Halo 3's Legendary ending. Just enjoy Halo 3 for the time being. Its the best game on the market and if you don't have Xbox Live, GO GET IT.
