Warhammer 40,000: Space Marine 2 has just closed out Year 2 of post-launch support with the Confrontation update, and Saber Interactive together with Focus Entertainment have announced the Year 3 roadmap, officially kicking off on October 1, 2026 with Patch 15 (the roadmap itself was published in late September) and running into 2027.
Chaos Siege Mode: Playing As Chaos Outside PvP For The First Time
The biggest highlight of Year 3 is a Chaos-themed version of Siege Mode currently in development, letting players experience the Chaos Space Marines faction in a way that's never been possible outside PvP. This marks the first time the community will be able to fight under the banner of Chaos in a large-scale cooperative mode, rather than only facing off directly against other players as before.
5 Major Updates And A New Class Arriving In Early 2027
Year 3 will include 5 major updates (Patches 15-19), bringing 2 new weapons, 2 new Operation bosses, alongside the Chaos Siege Mode content mentioned above. Most notably, a brand-new playable class (the community's most requested addition) will arrive in the first half of 2027, alongside an exclusive Champion Skin.
Season Pass 3: Space Wolves, Deathwatch, Exorcists
Season Pass 3 will bring new Champion and cosmetic packs for both familiar and first-time Chapters, made up of five cosmetic and Champion packs, with three names already confirmed: Space Wolves, Deathwatch and Exorcists. As with previous seasons, most new weapon and mission content will remain free for all players, while the Season Pass focuses on paid Chapter cosmetics and Champion Skins.
What Did Confrontation Bring To Close Out Year 2?
Before moving into Year 3, the Confrontation update closed out Year 2 with 2 new PvP maps (Sanctum and Facility) bringing the total number of Eternal War maps to 7, a new Terminus enemy in the Scarab Occult Terminator Sorcerer from the Thousand Sons, a new Ordeal system with weekly rewards, and 2 cosmetic packs closing out Season Pass 2: the Raptors Cosmetic Pack and Salamanders Champion Pack 2.
With the newly announced Year 3 roadmap, Space Marine 2 continues to be one of the most thoroughly supported live-service titles in the third-person shooter genre today, and this is only the first wave of confirmed content, full details are expected to be revealed gradually across upcoming updates.
What Patch 15 brings as Year 3 begins
Year 3 began on October 1, 2026 on PS5, Xbox Series X|S and PC, with Patch 15 (Anniversary Update 2) as the first free update; Focus and Saber published the Year 3 roadmap in a community update in late September (per Netto's Game Room). Chaos Siege Mode lets you play as Chaos Space Marines in PvE, across two new Siege sectors on the planet Avarax, fighting Tyranids, Cadians and loyalist Space Marines.
Patch 15 also adds the Crucible system: players take on "Penances," meaning debuffs and negative modifiers, to unlock rewards, including a Lamenters armor set. On the weapon side there is a One-Handed Thunder Hammer for the Tactical, Assault, Bulwark and Techmarine classes. Season Pass 3 opens with the Space Wolves Champion Pack (a Wolf Guard skin for the Bulwark with its own shield and hammer) and the Exorcists Cosmetic Pack of six armor pieces.
According to Focus's community update and DLCompare, Patch 16 (before the end of 2026) adds a PvP mode with "Weekly Stratagems" built on rotating modifiers, while Patch 17 (Q1 2027) brings the support-focused Apothecary class. Details of Patches 18 and 19 have not been announced, so OtaHub will not guess at what those two contain.
