Bungie has unveiled a comprehensive look at Symbiosis, a major update for Marathon arriving on December 8. The release introduces Expedition, a permanent cooperative PvE roguelite mode, alongside a beta for a PvP deathmatch mode and a new social hub named Limbo that features a firing range. To mark the launch, Bungie will host a free-to-play week running from December 8 through December 15, allowing newcomers to try the game and retain their progress if they purchase it. [1][2]
The update brings substantial new content to the shooter, including a robot samurai Runner shell named Bishop, who wields a sword. Players will also receive new weapons such as the Maverick pistol, throwing knives, hack grenades, and the V17 flamethrower. In addition, the Perimeter Zone map is receiving a visual refresh and expanded playable spaces, incorporating new points of interest like the Reservoir and an underground area called the Burrows. Bungie notes that Expedition represents phase one of its PvE roadmap, featuring randomized Flash Boost upgrades, escalating challenges, and a Tick Queen boss fight. [1][2]
