Focus Home and Saber Interactive pushed Hotfix 12.1 for Warhammer 40,000: Space Marine 2 on 5th March, and the Techmarine is the clear focus. The Replenishing Salvo perk has been fixed so it no longer burns its cooldown when your equipment is already full, which was a quietly annoying bug for anyone leaning on that build.

The bigger change is to Battlefield Repairs, which has been fully reworked. The new version reads: "Any Squad Member restores 1 additional Armour Segment for each Finisher of Majoris or Extremis enemy." That's a meaningful shift from whatever it was doing before, tying armour recovery directly to aggressive play rather than passive uptime. Inexorable Salvo also gets a buff, extending its effect for an additional 15 seconds after the ability deactivates.

For a hotfix, there's enough here to warrant a second look at your Techmarine loadout before your next Operations run. Full patch notes below.


Techmarine

  • Replenishing Salvo perk will not activate its cooldown when player has max equipment.
  • Reworked Battlefield Repairs perk. New description: “Any Squad Member restores 1 additional Armour Segment for each Finisher of Majoris or Extremis enemy.”
  • Inexorable Salvo perk buffed: ”The effect lasts for an additional 15 seconds after deactivation of ability.”
  • Decapitating Stratagem perk now correctly restores ability once it's fully empty. Previously it could restore ability after the first shot, if the player got a lucky kill, meaning that full ability restoration was mostly wasted.
  • Fixed cost of some Techmarine perks.

GENERAL FIXES

  • Crash fixes.
  • Fixed an issue that was blocking progress on Disruption (softlock after the Heldrake scene).
  • Added a voice preview in the voice selector menu.
  • Fixed an issue with Voice Pack VOs being not as loud as the rest of VOs.
  • Fixed an issue where Tarantula turrets could move a little bit after activation.
  • Lots of minor collision fixes on Disruption.
  • Lots of minor issues with various Battlefield Conditions.
  • Minor customisation fixes.
  • Minor localisation fixes.
