Halo: Campaign Evolved is getting a free Firefight mode this winter, adding four-player cooperative wave survival to the campaign remake. Halo Studios confirmed the update on November 12, but has not announced a download date.
The Xbox Wire announcement promises new maps where squads will fight successive waves of enemies. It does not name those maps or detail the mode's rules, matchmaking or split-screen support.
A new co-op mode beyond the campaign
Firefight gives returning squads a separate survival activity alongside the rebuilt Halo: Combat Evolved story. Campaign Evolved's announced release date was July 28, 2026, for Xbox Series X|S, PlayStation 5 and PC. This winter's release is an update to that game, not a new standalone Halo.
The existing campaign already supports up to four players online with crossplay and cross-progression, while two-player split-screen is limited to consoles, according to the official store listing. Those campaign features should not be taken as confirmation of Firefight's own connection or local-play options.
Halo Fest hands-on is not a launch date
Xbox FanFest attendees get the first chance to play on November 12. Halo Studios will share more details at Halo Fest in Seattle on December 12–13, where attendees can also play Firefight.
The official Halo Fest site lists a December 11 concert followed by the December 12–13 convention at the Seattle Convention Center's Arch building. Tickets are already sold out. The convention demo offers another early look, but Xbox has not tied the public update's release to that weekend.
