Space Marine 2 adds Terminator Sorcerers, Steam Workshop, and 10-player co-op via mods

Warhammer 40,000: Space Marine 2 just wrapped its second year of post-launch support with two back-to-back updates — Patch 14, the Confrontation Update, and a follow-up that brings Steam Workshop mod support to Saber Interactive's shooter.

Patch 14 is primarily a PvP push for the Eternal War mode, adding two new arenas: Sanctum, a medium-sized map, and Facility, which Saber describes as one of the most compact PvP maps in the game. Weekly PvP rewards are also in, letting players earn cosmetics and other unlocks through matches and challenges. On the co-op side, the update introduces the Scarab Occult Terminator Sorcerer — a miniboss that shows up across Operations mode and comes loaded with tricks: he can clone himself, teleport around the battlefield, and fire a powerful laser beam at players. Steam Workshop support arrived separately, and while it's early days for the mod scene, the standout release is the Astartes Overhaul — previously available on NexusMods — which rebalances Operations, adds three new classes (Terminator, Chaplain, and Apothecary), and introduces four new weapons including an Assault Bolter and an Artifex Bolt Rifle with optional incendiary bolts. Add-ons built on top of that mod push things further, including options to run six- or even nine-player squads, which combined with the base game's co-op slot means up to ten players at once. Other mods worth noting include Health on Executions, which makes finishers restore health in a style closer to Doom's glory kills, and Rogue Trader Tyranids, which reskins the game's enemies to match their 1985 tabletop models.

Space Marine 2 launched in September 2024 and quickly became one of the year's biggest hits, pulling in massive player numbers on Steam and earning strong reviews. Saber has kept up a steady cadence of free content updates since then, covering new Operations missions, PvP maps, and enemy types — making it one of the more actively supported games in the Warhammer 40K franchise's long history of licensed titles.

Saber has confirmed support continues for at least another year, though specifics are still under wraps. A full roadmap for year three is set to be revealed on the game's second anniversary this September.
