Marathon Gets PvE and Team Deathmatch on December 8

Marathon's next major step arrives on December 8, 2026, when Bungie's Symbiosis update adds the game's first dedicated permanent PvE mode and a competitive Team Deathmatch mode. The update is part of a broader plan to evolve the game over the next year, after a Nightfall refresh scheduled for October 2026.

For players, Symbiosis is meant to make Marathon less dependent on its most punishing format. The new PvE mode will let Runners explore, experiment, and tackle challenges without worrying about being hunted by other players. It also expands and visually overhauls the Perimeter map, adds Shell Bishop, a high-performance robot samurai, and introduces a social space with a built-in firing range. Bungie is also developing a friendlier onboarding experience for new and returning players, as outlined in the report on the planned changes.

Bungie says Marathon did not reach as many players as it had hoped and wants to broaden its appeal beyond a cutthroat, winner-takes-all PvEvP experience. A larger evolution is scheduled for March 2027, with interconnected permanent PvE, PvP, and PvEvP experiences, a refactored Cradle, deeper Shell progression, more focused questlines and narrative, new alien combatants, and an entirely new zone. The material gives no price or platform details for these updates, and announces no cast. Bungie says it plans to keep evolving Marathon throughout and beyond 2027.
