OK, im here to complain, about all u idiots that whinge and moan and make stupid petitions about there being no matchmaking for firefight, if you'd actually look up the reason about why no matchmaking for firefight maybe you'd see. If Bungie was to make firefight on matchmaking, Halo 3: ODST wouldn't be out yet, the campaign and firefight is made off the Halo 3 system, unless you'd like Halo: REACH delayed a few more years and Halo 3:ODST co-op campaign/firefight xbox live co-op servers taken down for a couple years to re-write the coding i'd shut up and be grateful for what you've got, just wait and see if Halo: Reach has firefight, it may because this will be more realistic and on a whole new engine with better graphics, overall... shut up whinging idiots about no matchmaking for firefight.
