Halo Studios will add Firefight, the series’ wave-based cooperative PvE mode, to Halo: Campaign Evolved as a free update this winter, the studio announced on Xbox Wire on November 12. The mode supports up to four players and becomes the first multiplayer content of any kind for the remake since launch.
“The tradition continues this winter as we add the four-player cooperative PvE mode to Halo: Campaign Evolved in a free update.” wrote Tahir Hasangjekaj, Director of Competitive Engagement at Halo Studios, in the announcement post. Xbox CEO Asha Sharma confirmed the news on X the same day, saying Firefight was coming as a free update this winter.
Firefight, but no arena multiplayer yet
For players hoping the announcement would close the remake’s biggest gap, the answer is only partial. Halo: Campaign Evolved launched on July 28, 2026 with no multiplayer modes at all, and reviews flagged the absence. What is arriving is a defense-based horde mode, playable solo or in co-op against progressively harder waves with gameplay modifiers, not the arena competitive multiplayer many fans wanted from a Halo remake. Arena modes like Team Deathmatch remain unconfirmed for the game.
Firefight has a long track record in the franchise. It debuted in Halo 3: ODST in 2009 and has since been added to several recent entries after launch, and this is the first time it has been retroactively brought to the original Halo entry. Most of Campaign Evolved’s post-launch updates so far have been free cosmetic DLC, so a full mode at no charge marks a shift, not unlike DOOM: The Dark Ages getting its free endless Slaughter Mode.
Details and first hands-on at Halo Fest
There is no release date yet beyond “this winter.” Halo Studios says more details about the Firefight update will be shared at Halo Fest, held December 12 and 13 in Seattle, where attendees can play the mode throughout the weekend. Xbox FanFest attendees on November 12 got the first hands-on with Firefight across new maps and with plenty of weapons.
The reveal lands during the 25th anniversary of both Halo and Xbox, a milestone Microsoft is marking with anniversary hardware and events. Halo: Campaign Evolved is available on PlayStation 5, Xbox Series X|S, PC and Game Pass, with a Standard Edition at $49.99 and a Premium Edition at $69.99. The free Firefight update arrives this winter, with full details due at Halo Fest on December 12.
