Microsoft is expanding Halo: Campaign Evolved with another major addition, as Halo Studios has announced that the fan-favorite Firefight mode is coming to the game in a free update this winter. The update will introduce four-player cooperative PvE gameplay, giving players another reason to return to the battlefield alongside their friends.

Firefight has been a recognizable part of the Halo franchise for nearly two decades, challenging players to work together against increasingly dangerous waves of enemies. Rather than competing against one another, players must coordinate their efforts, hold their positions, and survive as long as possible. Its arrival in Halo: Campaign Evolved will give the remake another cooperative experience beyond its main campaign.

The first opportunity to experience the new mode is taking place at Xbox FanFest, where attendees will be able to get hands-on with Firefight across new maps and with a selection of weapons. However, those who cannot attend the event will have to wait for the wider release, which is currently planned for this winter.

Halo Studios has also confirmed that additional information about the free update will be shared during Halo Fest, taking place December 12-13 in Seattle, Washington. Attendees will have another opportunity to play Firefight throughout the weekend, suggesting that the event will provide a closer look at what players can expect when the update eventually arrives.

While a specific release date has yet to be announced, the addition of Firefight gives Halo: Campaign Evolved another way to bring players together. The update will be available at no additional cost to existing players, with the game currently available for PlayStation 5, Xbox Series X|S, and PC.
