Bungie has announced the Symbiosis update for Marathon will launch on December 8. Targeting PS5 players, the update introduces a range of new content including fresh PvE and PvP modes, new weapons, and an expanded Perimeter zone to explore on Tau Ceti IV.
The update is accompanied by an Open Play Week running from December 8 to 15, allowing players to experience Marathon across PS5 with full cross-play and cross-save functionality. The Symbiosis update requires an internet connection and a paid console subscription for online access.
Expanded Zones and New Game Modes
The Perimeter zone receives significant changes in the Symbiosis update. Fungal growth and alien lifeforms have altered the landscape, introducing new playable areas such as the underground Burrows and the submerged Reservoir. Players will have to contend with the Tick Queen, a new threat lurking beneath the surface.
A new PvE-focused mode called Expedition debuts as Phase 1 of a multi-run series. Players can engage solo or in crews, tackling fresh combat and environmental encounters without PvP interference. Expedition also features Flash Boosts, which allow players to customise their loadout during each run.
For PvP enthusiasts, the update delivers a beta Deathmatch mode. This 3v3 Team Deathmatch pits two crews against one another in shorter matches where players compete for points but do not risk their permanent loadouts. This mode is intended as an experimental addition to the game’s multiplayer options.
Additional Features and Platform Details
The Symbiosis update adds Limbo, a social hub space where players can interact, test weapons and gear in firing ranges, and engage in duels. A new Runner shell called Bishop is introduced, themed around a fast, blade-wielding robot design.
On the weapons front, two new options arrive: the V17 Flamethrower, which offers close-range area denial, and the Maverick, a new revolver archetype designed to evoke a hand-cannon feel.
Marathon is available exclusively on PS5 and supports cross-play and cross-save across other platforms, provided players link their Bungie.net accounts. The Symbiosis update will be available to all Marathon owners from December 8.
