Warhammer 40,000: Space Marine 2

Patch 15 delivered the period’s biggest drop, adding Chaos Siege—where players controlled Heretic Astartes across two Avarax sectors—and Crucible, a Level 25 endgame PvE mode with the Lamenters armour set as a reward. Patch 16 followed with six new Heroic Weapons, while the Apothecary remained an announced Patch 17 class rather than a released addition.

• Combat tuning: The One-Handed Thunder Hammer received faster charging, a 10% base-damage increase, a 67% Underhand Swing increase, and stronger Energy Loop and Charged Impact attacks. Melta Rifles gained improved damage falloff, a 12-round default ammo pool, and six-round magazines, while Tactical perks and firearm damage received additional tuning.
• Chaos on Avarax: The community event challenged players to survive 15 waves in Chaos Siege for 100 Accolades; the Halloween Screenshot Contest offered Year 3 Pass keys to winners.
• Public Test Server: The PTS reopened on November 10 with maxed levels, all weapons unlocked, multiplayer including private PvP lobbies, and dedicated feedback threads. The Apothecary was announced for Patch 17 in early 2027, but was not yet available.

Patch 12’s Techmarine Update was the year’s biggest content drop, adding the Techmarine class, its Omnissian Axe, Tarantula Sentry Guns, Restorative Stimms, and the Disruption PvE operation. Siege 2.0 and Chaos Siege Mode later substantially expanded the endgame, while Season Pass 2 delivered several new Chapter-themed cosmetics.

• Siege 2.0: The Siege mode overhaul added Blessings and Atonements, new bosses including the Hive Tyrant and Mutalith Vortex Beast, random side objectives, weekly Accolade rewards, new weapon skins, and a revised difficulty and timer structure. The same update introduced the Purgation operation, Bolt Carbine Sidearm, Battle Simulator, Trials of Resolve, Wargear 2.0, perk loadouts, and shared Wargear.
• Season Pass 2: The Raven Guard Champion Pack and Carcharodons Chapter Pack arrived alongside new armour and weapon cosmetics, followed by the Iron Hands Chapter Pack with a Techmarine Champion and Omnissian Axe skin. The Blood Angels Champion Pack and Salamanders Cosmetic Pack also expanded Chapter customization.
• Steam Workshop: Official mod support launched through Steam Workshop, with modded sessions separated into private lobbies and progression kept apart from the official game. Balance updates also strengthened PvE firearms, reduced enemy resistance growth, and improved Sniper, Vanguard, and Assault builds.
