Xbox reveals free winter Firefight co-op update for Halo: Campaign Evolved

Xbox revealed a free update for Halo: Campaign Evolved at its FanFest event on November 12, 2026, adding the four-player player-versus-environment Firefight mode, in which Spartans fight computer-controlled enemies; event attendees played it first, and existing players will pay nothing for it.

Tahir Hasangjekaj, director of competitive engagement at Halo Studios, announced the update and described Firefight as a favorite part of Halo for nearly two decades. He described it as a returning tradition in which Spartans team up to survive repeated waves of enemy attacks, and FanFest attendees were the first to play it across new maps with additional weaponry.

Firefight is a cooperative mode in which four Spartans team up to survive repeated enemy waves. The mode joins the game as a standalone survival challenge built on repeated enemy waves, separate from the game’s existing campaign co-op options. Halo: Campaign Evolved already supports solo play, split-screen co-op for two players sharing one screen on consoles, and online co-op for up to four players. Crossplay lets console and PC players play together, and cross-progression carries progress between platforms.

Halo: Campaign Evolved is a modernized remake built on the Halo: Combat Evolved campaign, out now on PlayStation 5 and Xbox Series consoles, on PC through Steam and Microsoft Store, and via Game Pass. The update joins a broader remake package that adds nine additional iconic weapons, lets players hijack enemy vehicles and pilot a drivable Wraith tank, and includes Skull modifiers that randomize weapons, enemies and environments.

Halo Studios plans to reveal more about the Firefight update at the December 12-13 Halo Fest in Seattle, Washington, and attendees will be able to play the mode all weekend. The studio marked the event as part of 25 years of Halo and Xbox and described Halo Fest as the next reveal after Xbox FanFest.

The two outlets disagree on the date of Halo Fest. An October report from TweakTown cited December 11-13 for Halo Fan Fest, while the official announcement sets Halo Fest for December 12-13 in Seattle.

Rebs Gaming’s October 7 report said Firefight and Theater were planned for a winter update, built by a small Halo Studios team of about 30 people apart from Activision’s new mainline Halo team. The report said Pierre Hintze handled operations management after Bonnie Ross left in 2022, and suggested the update might arrive without advance notice around Halo Fan Fest on December 11-13 before Xbox’s official announcement.

According to Push Square, Halo: Campaign Evolved launched in July and has struggled commercially, and the free Firefight update could bring a spike in users. The outlet presented that commercial picture as context for the game’s players after its mid-year launch.

According to Pure Xbox, Halo: Campaign Evolved faced backlash over missing multiplayer options, particularly player-versus-player modes and Firefight. The outlet said the criticism might be unfair, since the game was sold as a campaign remake, and it called fan reaction understandable given that campaign-focused positioning.

Push Square also suggested this Firefight update might be the final Halo Studios-led release, describing the developer as effectively a support team. The outlet called this its own view, not an official word from Xbox or Halo Studios.

TweakTown said fans had built a Firefight mod for Halo: Campaign Evolved that turned The Silent Cartographer into an endless arcade survival battle. The report grouped that project with wider fan work, including recomps and multiplayer server browsers.
