Marathon's Symbiosis update arrives on 8 December
Bungie has detailed the contents of the first major update on the PlayStation Blog: new PvE and PvP modes, weapons, a new Runner shell and a Free Play Week from 8 to 15 December. In the meantime, Sponsored Survival is live for PvE players.

Symbiosis, the update for Marathon, Bungie's shooter already available on PS5, Xbox Series X|S and PC, arrives on 8 December. The first details were published on 10 November on the PlayStation Blog, in Italian as well.
In the Perimeter zone, transformed by fungal growth and alien life forms, the playable spaces Burrows and Reservoir are added, along with an encounter with the Tick Queen. Expedition is the first phase of a PvE-only mode built around a series of three runs, solo or in a squad, with Flash Boost to tweak your build mid-match. Deathmatch arrives in beta, a points-based 3v3 in which permanent gear is not at risk. Limbo is a new social space with shooting ranges and a duelling pit.
Also added are the Bishop Runner shell, described as an agile, blade-wielding robot, the V17 flamethrower and the Maverick revolver. Alongside the launch, from 8 to 15 December, there will be a Free Play Week. Sony notes that Marathon on PS5 supports cross-play and cross-save, with the requirements listed on the official post.
In the meantime, on 11 November the game's official account announced that Sponsored Survival, the PvE activity with sponsored kits and Rooks, will stay live until the end of the Nightfall Refresh phase, which began on 6 October. In September Bungie had explained that the mode would rotate weekly through Perimeter, Day Marsh, Night Marsh and Outpost, ahead of the first permanent PvE experience, the one coming with Symbiosis.
