Marathon Symbiosis update launches December 8, adding new PvE and PvP modes, weapons, and more

Marathon‘s Symbiosis update arrives December 8, bringing new PvE and PvP modes, weapons, a Runner shell, and expanded areas to explore on Tau Ceti IV. Today we’ve got first details on the updated Perimeter zone, Expedition mode, and more. 

What’s new in Marathon: Symbiosis 

Updated Perimeter zone: Fungal growth and alien life have transformed Perimeter, introducing new playable spaces including the underground Burrows and submerged Reservoir. Runners will also encounter the Tick Queen, who lurks deep beneath the surface. 

Expedition: Phase 1 of a new PvE-only mode built around a three-run series. Play solo or with a crew, face new combat and environmental challenges without PvP threats, and use Flash Boosts to shape your build during a run.  

Deathmatch (Beta): An experimental PvP mode featuring bite-sized 3v3 Team Deathmatch matches. Two crews compete for points without risking their permanent loadouts. 

Limbo: A new social space where Runners can connect, test weapons and gear in firing ranges, and challenge each other in a dueling pit. 

Bishop Runner shell: A new Runner shell built around the fantasy of a fast, surgical blade-wielding robot. 

New weapons: The V17 Flamethrower brings short-range area denial, while the Maverick introduces a new revolver archetype with a hand-cannon feel.
