Halo: Campaign Evolved is getting Firefight in a free update this winter, giving four players the opportunity to stand their ground against waves of enemies. Apparently saving the day through the campaign wasn’t quite enough work for one Spartan, so it’s time to bring some mates.
Halo Studios confirmed the cooperative PvE addition as part of Xbox’s anniversary celebrations on 12 November. The announcement promises new maps and plenty of weapons, although it stops short of naming the full selection or putting an exact date on the public release.

That last point is worth keeping straight before anyone clears their weekend. Winter is the confirmed window, with more information due at Halo Fest in Seattle on 12 and 13 December. Those event dates are a chance to hear more and play the mode in person, rather than a confirmed launch date for the update.
Xbox FanFest attendees were given the first opportunity to try Firefight on the night of the announcement. Halo Fest visitors will also be able to play it throughout that weekend, so the December event will offer another public look at what the team has been building.
The appeal is straightforward enough: a squad of four, an increasingly unfriendly battlefield and the shared responsibility of keeping everyone alive. It gives players a cooperative survival option alongside Campaign Evolved’s story, with the update itself confirmed as free.
We found the news through VGC and verified it with Halo Studios’ official announcement and Xbox Wire. There’s no detailed map list or firm release day to report yet, but the four-player format and winter window are official.
