Bungie has set December 8 for Symbiosis, which adds a cooperative Expedition, a 3v3 deathmatch beta and a week of open play. Expedition is a series of three runs against the environment, playable alone or in a crew. Temporary Flash Boosts change the build during a run. The deathmatch beta pits two three-person crews

against one another without putting their permanent loadouts on the line. Bungie also revealed Limbo, a shared space with firing ranges and a duelling pit. Open Play Week runs December 8–15 alongside the update. Official source. Image: Bungie / PlayStation Blog. Official image source.
