Halo: Campaign Evolved will add Firefight for free this winter, with cooperative PvE matches for up to four players. Xbox has announced that the mode will include new maps and weapons; there is still no specific date for the update.
Xbox Game Studios and Halo Studios made the announcement on November 12, during events marking Xbox’s 25th anniversary. The update brings back a mode focused on surviving waves of enemies and expands the remake’s cooperative options beyond its campaign missions.
“The tradition continues this winter when we add the four-player cooperative PvE mode to Halo: Campaign Evolved in a free update.”
— Tahir Hasandjekaj, director of competitive engagement at Halo Studios

Waves of enemies and matches for four
Firefight pits a group of players against successive waves of enemies: the goal is to work together and hold out, not compete against other teams. Xbox describes it as a cooperative PvE experience for four players.
The mode debuted in Halo 3: ODST in 2009 and has become one of the franchise’s recognizable modes. This time, it is being added to Campaign Evolved in a post-launch update, rather than being part of the game’s initial offering. Game Informer describes this as the first time Firefight has been added retroactively to the original installment.
The Campaign Evolved version will have new maps and weapons, according to Xbox’s announcement. Vandal notes that details on how matches will be configured have also not been shared.
FanFest has already offered a chance to try it
Attendees at Xbox FanFest on November 12 were the first to play this version of Firefight. The official presentation previewed the chance to try it on new maps, with an arsenal of weapons designed to help them take on the enemies. The playable demo confirms that the mode has already been shown to the public, though that does not establish when it will be available to all players.
The next announced event is Halo Fest in Seattle, on December 12 and 13. Xbox has promised to share more details about the update there and give attendees the chance to play Firefight over the weekend. This is an opportunity to learn more about the content and try it at the event, not a confirmed release date.
For now, the release window remains “this winter.” Neither Xbox nor Halo Studios has specified a day or month for the download.

A cooperative alternative outside the campaign
Until now, the cooperative experience in Campaign Evolved has focused on playing through the story: up to four people could play online, while consoles supported two players in split-screen. Firefight will offer another group activity, based on surviving waves rather than replaying Master Chief’s missions.
The addition does not mean the return of competitive multiplayer. Vandal notes that this component is still absent from the remake; Firefight, by contrast, pits players against enemies controlled by the game. The announcement is limited to this cooperative mode and includes no information about other multiplayer modes.
Halo: Campaign Evolved has been available since July 28, 2026, for PS5, Xbox Series X|S, and PC. Vandal describes it as a remake of the Halo: Combat Evolved campaign, with updated graphics and controls, as well as three new missions starring Master Chief and Sergeant Johnson. Firefight will expand that offering with an activity separate from the campaign.
The announcement comes amid a Halo reorganization
The news arrives at a time of change for the franchise. Eurogamer links the announcement to Xbox’s restructuring and the uncertain future of Halo Studios, while Game Informer reports that Microsoft is handing the franchise over to Activision. No specific plans for the series’ next mainline game have been announced in this update.
Eurogamer mentions rumors of a possible Halo reboot developed by Sledgehammer Games, the studio associated with Call of Duty, but does not present them as a confirmed project. The Firefight update also does not clarify who will develop the next installment or what direction it will take. Its announcement is limited to free content for Campaign Evolved.
The mode is also part of the celebrations marking 25 years of Xbox and Halo. Xbox recalled that Halo accompanied the launch of the original console and placed the Firefight announcement within those celebrations. The company has not announced a price because the update will be free for people who own the game.
The next official update is scheduled for Halo Fest in December. Until then, the release date, number of maps and weapons, and other match details remain unknown. What has been confirmed is that Firefight will offer four-player cooperative PvE and arrive in Halo: Campaign Evolved at no extra cost this winter.
