Marathon's Symbiosis Update Lands December 8 With Expedition PvE, Deathmatch Beta, and New Weapons

OFFICIAL Written by GPN · Nov 10, 2026, 10:57 AM ET · Marathon · Gaming

Marathon's next big update has a date. Symbiosis arrives on December 8, bringing new modes, new areas, new gear, and a free Open Play Week so anyone can try the game.

Perimeter zone

Fungal growth and alien life have reshaped the Perimeter zone, opening up new playable spaces including the underground Burrows and the submerged Reservoir. Runners will also run into the Tick Queen, who lurks deep beneath the surface.

Expedition

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

Deathmatch beta

Deathmatch is an experimental PvP mode of bite-sized 3v3 Team Deathmatch matches. Two crews compete for points without risking their permanent loadouts.

Limbo

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

New Runner shell and weapons

The Bishop Runner shell is built around the fantasy of a fast, surgical blade-wielding robot. Two new weapons join the arsenal: the V17 Flamethrower, for short-range area denial, and the Maverick, a new revolver archetype with a hand-cannon feel.

Open Play Week

Players can experience Marathon during Open Play Week, running December 8 to 15, alongside the launch of Symbiosis. Marathon is available now on PS5, with full cross-play and cross-save support.
