Bungie is overhauling Marathon by adding a permanent PvE mode called Symbiosis in December and moving away from strict seasonal schedules, responding to player feedback for more depth and variety. These changes come after Sony laid off most of Destiny's team and some Marathon developers in June, forcing the studio to reset its original extraction shooter vision.
Bungie has delayed Marathon's September seasonal update to December and abandoned its seasonal model, citing the need to rebuild the extraction shooter based on player feedback for more depth and progression. The studio will release a smaller October update focused on progression reset and economy refresh, followed by the major Symbiosis update in December featuring a dedicated PvE mode, new social space, and improved onboarding.
Blizzard has ended annual expansions for Diablo 4 following the release of two major expansions since 2023, shifting focus to seasonal stories leading up to Diablo 5's spring 2029 launch. The current game's story arc concluded with Lord of Hatred, though seasonal content will continue as the game bridges toward its sequel set 100 years in the future.
