Its biggest weapon adjustments are substantial PvE damage increases for the One-Handed Thunder Hammer, while the forced stagger from charging stances has been temporarily removed. The official notes do not establish broad player praise or a sweeping reversal.
What changed in Space Marine 2 Hotfix 15.1?
Hotfix 15.1 is the official patch-notes label for the October 8 update. It followed Patch 15, also called Anniversary Update II, which launched October 1 for PlayStation 5, Xbox Series, and PC. The hotfix includes weapon tuning, bug fixes, and changes to Crucible and Chaos Siege. The official Hotfix 15.1 notes list the changes; Focus Entertainment’s launch announcement describes Anniversary Update II.

How did the One-Handed Thunder Hammer change?
In PvE, Hotfix 15.1 raises several damage values for the One-Handed Thunder Hammer:
- Base damage: increased by 10%.
- Underhand Swing damage: increased by 67%.
- Echoing Swing wave damage: increased by 100%.
- Energised Strike damage: increased by 100%, and its radius increased by 50%.
- Charged attack damage: increased by 25%, with improved cleave.
These are patch-setting changes, not measurements of how much damage every player will deal in a particular encounter. The October 1 announcement says the weapon is available to Tactical, Assault, Bulwark, and Techmarine classes.

Was the charging-stance stagger removed permanently?
No. The hotfix temporarily removes the forced stagger from charging stances. The official notes say: “It will return in the next patch, once we make it less spammable.” The notes do not name an individual speaker or give a more precise schedule for that return.
What changed for Melta rifles?
The notes adjust selected damage-falloff start distances across Melta Rifle variants, rather than describing one identical change for every Melta weapon. For the default Melta Rifle, the ammo pool increases by two, to 12, and the magazine size increases by one, to six. The published changes distinguish variants, so those default-rifle ammunition figures should not be applied to the Heavy Melta Rifle.
Rank #2
- Brand new. UK Import PAL version. Game in English. UK PSN account may be required for any online features.
What else does the hotfix change?
- In Chaos Siege, the Summonable Hellbrute’s melee damage is reduced by 30%.
- A fix restores Auspex Scan behavior to Patch 14.2: it no longer buffs Gunstrike damage by default without perks.
- The notes also list changes involving Crucible, customization, and general bugs.
The percentage adjustments are game settings recorded in the patch notes; they do not by themselves quantify the effect on overall balance or player experience.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Does this prove Saber rolled back controversial Patch 15 changes?
No. The official notes support describing Hotfix 15.1 as a set of targeted adjustments and fixes. They do not establish a broad rollback of Patch 15, identify every change as a reversal of a specific earlier nerf, or show that players generally praised the update. The October 8 MP1st report’s headline uses rollback-style framing, but that report’s detailed claims are not available to verify here: MP1st’s October 8 update report.

For context, Focus Entertainment’s September 24 community update described Patch 15 and Patch 16 as remaining roadmap items for 2026, and the Apothecary class as planned for Patch 17 in Q1 2027. These were announced plans, not guarantees: September Community Update.
Is Season Pass 3 required for Hotfix 15.1?
No. The hotfix is a game update; the official materials do not say that Season Pass 3 is required to receive it. Focus’s Anniversary Update II announcement separately mentions two cosmetic DLCs for Season Pass 3 holders. That cosmetic content is distinct from the hotfix.
