Marathon Symbiosis Update Adds Co-Op PvE Roguelite Mode and Limbo Social Space
Bungie's Symbiosis update lands December 8 with the Expedition PvE mode, a Deathmatch beta, the Limbo social hub, a new Bishop shell and a free Open Play Week.
Bungie has released a first gameplay trailer for Marathon's Symbiosis update, and it shows a co-op PvE roguelite mode and a new social hub. According to PC Gamer, Bungie describes Symbiosis as the start of "the evolution of Marathon," with "a plethora of updates and changes" planned.
Key facts
- Marathon's Symbiosis update launches December 8 for all players.
- Expedition is a new PvE-only mode built around a three-run series.
- Limbo, a social space with firing ranges and a dueling pit, arrives too.
- Open Play Week runs December 8–15, with progress carrying over if you buy the game.
What the trailer and PlayStation.Blog show
Expedition is the headline addition. PlayStation.Blog describes it as Phase 1 of a new PvE-only mode built around a three-run series. Players can go solo or bring a crew, face new combat and environmental challenges without PvP threats, and use Flash Boosts to shape their build during a run.
PC Gamer reports that the PvE mode is now permanent and has a new name, Expedition. It adds that Bungie calling this "phase one" of its PvE plan suggests the mode is still a work in progress. Details beyond the teaser haven't been revealed.
Limbo is the new social space. Runners can connect, test weapons and gear in firing ranges, and challenge each other in a dueling pit. Pure Xbox compared it to the Tower from Destiny 2.
Deathmatch (Beta) is an experimental PvP mode with 3v3 Team Deathmatch matches. Two crews compete for points without risking their permanent loadouts.
Map, shell and weapons
The Perimeter zone is being reworked. Fungal growth and alien life have transformed it, adding the underground Burrows and the submerged Reservoir. Runners will also meet the Tick Queen, who lurks deep beneath the surface.
A new Runner shell, Bishop, is built around the fantasy of a fast, surgical blade-wielding robot. PC Gamer noted that early reaction on Reddit and social media appears positive, with Bishop already gaining fans.
Two new weapons are coming:
- V17 Flamethrower: short-range area denial.
- Maverick: a new revolver archetype with a hand-cannon feel.
Open Play Week
Symbiosis launches alongside Open Play Week, which runs December 8–15. PC Gamer says the game will be fully free to play during that period, including the new modes and content. If you then buy the game, progress and items earned carry over.
PlayStation.Blog says Marathon is available now on PS5 with full cross-play and cross-save support. Console play requires internet access and a paid subscription, and cross-save needs a Bungie.net account linked to each system you play on.
What it means for you
If you've been curious about Marathon, Open Play Week is a low-risk way to try Expedition, Limbo and the Deathmatch beta without buying the game. The Symbiosis update launches December 8 for all players. Bungie hasn't yet shared more detail on how Expedition works beyond the three-run structure and Flash Boosts.
