You guys obviously have not been reading up on Halo 2. There's so many magazine articles confirming Covenant vs. MC battles on multiplayer. On EGM's November 2002 issue they covered the issue: (-begin quote-) Bungie will be able to stop drooling and we can start: Halo 2 will feature online battles between Masterchief characters on one side and Covenant Elite soldiers on the other. The plan is for online to support "at least" 12 to 16 players(so I'm guessing they want more). It'll be nothing less than the total online war Bungie originally envisioned."( -end quote-)
