Warhammer 40,000: Space Marine 2 has its long-awaited Patch 10 across PC, PlayStation 5, and Xbox Series X and S. This is the big anniversary update that makes a number of significant changes and additions to Saber Interactive’s explosive third-person action game.
It’s worth noting that while Patch 10 is live now, Season Pass 2 and the Black Templars and Imperial Fists cosmetics do not go live until later today, September 4.
Patch 10.0 adds new game modes and maps, along with the Chaos Armour Pack, Champion Customisation, new weapons, and more.
The Chaos Armour Pack is available for free. You can finally change the armour set of your Heretic Astartes in PvP, but you have to unlock the set first. Each class requires you to score a certain amount of kills per match to unlock the corresponding skin.
The new PvP mode is Helbrute Onslaught, which is playable on all maps. Two teams of Chaos Marines fight to control strategic areas, but also to take control of the Helbrute. The first team to take control of an objective gets to control the Helbrute, until the opposite team takes it down. One player gets to control the Helbrute at a time, and this player is picked randomly among players who participated in securing the control point. For the team that failed to secure the first control point to have the Helbrute on their side, they need to slay their opponents’ Helbrute and secure a new designated control point.
Controlling the Helbrute grants the team a strong advantage, but killing it rewards significant amounts of points to your team. The Helbrute uses a Helbrute Thunder Hammer in melee and a Plasma Cannon in range, and it can unleash a battle cry with its special skill to regenerate its HP.
Stratagems is a new PvE game mode. Unlike classic Operations, there are only two difficulty modes: Normal and Hard. What makes this new game mode different are the various Battlefield Conditions, which change every day and week and make each operation different.
Battlefield Conditions can either help or hinder your progress. Upon successful completion, you receive a new currency called Accolades, which can be exchanged for valuable rewards.
There are weekly and daily Stratagems, and each Operation has its own set of modifiers. Publisher Focus Entertainment provided a few examples:
Meanwhile, there are new PvP and PvE maps, the new Power Axe weapon (fans of the Warhammer 40,000 episode from Amazon's Secret Level animated anthology series have been calling for this one for some time now), the Pyreblaster and Pyrecannon for PvE only, the new Hero Weapon Variants, and the new Mutalith Vortex Beast and Chaos Spawn enemy, the latter of which is seen in the image below. The Chaos Spawn comes in three variations, and is swifter and more agile than its bulk suggests. Focus warned players to expect a tough fight.
Check out the Update 10.0 patch notes below. The Techmarine, Space Marine 2’s first new class, is due out early 2026 with patch 12.
Last month, Focus lifted the lid on Space Marine 2's second year of DLC, confirming patches 10 all the way up to 15, which takes us up to the end of the second quarter of next year (June 2026). On the way is a new Battle Barge expansion and a new Siege map coming Q2 2026.
Throughout the year, the Season Pass II will grant players nine new DLCs, with new Champion skins, armour pieces, and heraldry markings. While existing Chapters like the Blood Angels and Salamanders are to receive new cosmetics, fan-favorite Chapters like the Raptors, Iron Hands, and Carcharodons will get their due time in the spotlight.
NEW FEATURES
NEW OPERATION: VORTEX
In Vortex, you'll return to the Astropathic Relay on Avarax, which has once again fallen silent. Your task is to investigate and cleanse the Relay of lingering heretical presence, and confront a mighty enemy lurking in its deepest levels.
Mutalith Vortex Beast is a new boss in Operation Vortex. It is a towering, warp-twisted monstrosity that drags reality into spiraling chaos. It rends and crashes with its claws and unleashes storms of sorcerous energy upon the Astartes.
Chaos Spawns are new Majoris enemies that can appear in all Operations featuring the Thousand Sons.
Chaos Spawns are dark abominations, powerful melee units infused with forbidden sorcery. They are fearsome opponents, especially when encountered in greater numbers. Their varied mutated limbs grant them a highly diverse and lethal moveset. However, it is an Astartes’ duty to study them and purge the heresy.
NEW WEAPONS
The Power Axe is a swift, aggressive power weapon capable of delivering relentless, infinitely chaining attacks. Wielded by the Vanguard, Assault and Bulwark classes, it allows a Space Marine to unleash a hail of blows upon their foes.
This is a fierce yet tactical weapon. Successfully executed perfect parry puts the Marine in a Power Stance, creating a moment of tactical choice: step back and release a devastating Power Wave or press forward to continue the fearsome combo.
In this update, we are introducing a new weapon: the Pyreblaster & Pyrecannon, for the Tactical and Heavy classes.
The flamer weapons now apply a burning effect on enemies, which inflicts significant damage over time (which scales based on difficulty). In addition to that, flames also slow down Minoris enemies.
An effective strategy would be to try to set as many enemies on fire and keep them burning.
Battlefield Conditions change weekly and daily, completing a Stratagem grants a new currency called “Accolades”.
Reworked Data Refinement Shop on Battle Barge:
The “Data Refinement” shop has been renamed and now offers a variety of additional items. Now, it will also redeem old Community Giveaways and Accolades items.
You can spend Accolades in the "Refinement & Redemption" shop to unlock unique items.
NEW PVP MODE: HELBRUTE ONSLAUGHT
Two teams of Chaos Marines will fight to control strategic areas, but also to take control of the Helbrute. The first team to take control of an objective gets to control the Helbrute, until the opposite team takes it down. One player gets to control the Helbrute at a time, and this player will be picked randomly among players who participated in securing the control point. For the team that failed to secure the first control point to have the Helbrute on their side, they will need to slay their opponents’ Helbrute and secure a new designated control point.
Controlling the Helbrute grants the team a strong advantage, but killing it rewards significant amounts of points to your team. One last thing, the Helbrute uses a Helbrute Thunder Hammer in melee, and a Plasma Cannon in range, and it can unleash a battle cry with its special skill to regenerate its HP.
ADDED 6 CHAOS RELIC ARMOUR SETS FOR PVP
These Armour Sets are now available to unlock by playing and scoring kills in Eternal War mode. For each skin, you will have to get 9 kills in more than 9 Eternal War matches to unlock the skin of the class you’re playing.
This long awaited feature is now available! You can now mix various parts of the Champion’s Armours on different classes.
Please note that not every armour part will be available for mixing in every class.
NEW SEASON PASS CONTENT:
GAMEPLAY & BALANCING TWEAKS
PVE WEAPONS
Bolt Pistol: Headshot damage coefficient increased from 1.15 to 1.25 for all versions.
Master-Crafted Bolt Pistol Alpha
Salvation of Bakka Artificer Bolt Pistol
Gathalamor Crusade Relic Bolt Pistol
Auto Bolt Rifle:
The Auto Bolt rifle suffers from that "default" gun syndrome that you swap to something more interesting immediately. The problem is that other guns, like Bolt Rifle, Bolt Carbine, Stalker Bolter and even Heavy Bolt Rifle are always going to be more specialized and more effective at what they do no matter what. Since the gun has a very limited number of versions, its perk tree is also very, very limited and it's difficult to find a gameplay role with it. The correct move would probably be to merge it with Bolt Rifle variants, but the problem is that it would mess up with saves too much and that drastic move is too risky.
With this update we are going to try to make it a mix of all bolters, to make that "default" gun at least more effective, but I fear that this gun will always be outshadowed by more specialized bolters.
Heavy Bolt Rifle: Headshot damage coefficient increased from 1.15 to 1.25 for all versions except Drogos Reclamation and Ophelian Liberation.
MELEE
Chainsword: Speed increased for all block versions.
Power Sword: Speed increased for all block versions.
Thunder Hammer:
The biggest issue of the Thunder Hammer right now is its contested health recovery, not its overall effectiveness. This will be addressed during contested health recovery rework. But at the moment, we wanted to improve it so it won’t feel like a worse version of other melee weapons.
GAMEPLAY QOL
With this update we are expanding Bulwark's shield moveset to make shield based perk builds more interesting. We are going to continue doing this for other classes. While we think that overall Classes balance is good, the build variety within class could be improved and this cannot be done by simply tweaking numbers.
PVP WEAPONS
Las Fusil: Charging speed decreased from 1.1 sec to 1 sec.
Stalker Bolt Rifle: Rate Of Fire increased from 150 shots per minute to 170 shots per minute.
Occulus Bolt Carbine: Full damage range increased from 20 meters to 30 meters.
Marksman Bolt Carbine: Headshot damage multiplier increased from 1.6 to 1.8.
Plasma Incinerator: Common Shot damage decreased by 15%.
Plasma damage: Fixed a bug where a player in a roll animation could not receive damage from plasma weapons.
Thunder Hammer: Fixed issue that caused the Thunder Hammer to have a longer reach.
Sniper’s Camo Cloak Ability: Ability cooldown increased from 25 seconds to 35 seconds.
Assault’s Jump Pack Ability
Bulwark: Bulwarks can now be knocked out of a shield stance if they take a lot of damage from enemies within 5 seconds.
Extended Weapon arsenal in PvP: Added Power Axe to Assault, Vanguard, Bulwark
XP Recalculated: The amount of experience required to earn rewards has been reduced, making progression faster and more rewarding.
New Levels Added: We've expanded the progression system. The new max level is 48.
OPERATIONS
Reliquary
All: Lots of minor fixes with level geometry.
SIEGE MODE
Carnifex: Fixed an issue causing the Carnifex to be too aggressive and too accurate with its ranged attacks.
All: Lots of minor fixes with animations.
GENERAL FIXES
We've got plenty more on Space Marine 2 from our gamescom 2025 interview with Saber development chief Tim Willits. He spoke about how a large chunk of fans have "assumptions" about the Warhammer 40,000 universe that are incorrect as a result of the huge success of the game, why delaying Space Marine 2 was the best thing Saber ever did, and, of course, Space Marine 3.
