Warhammer 40000 Space Marine 2 Patch 9.0 has officially gone live across PS5, Xbox Series X|S, and PC. Dubbed the Quality of Life Update, this release brings sweeping adjustments across PvE and PvP, including a massive melee weapon overhaul, Datavault improvements, Siege Mode balance tweaks, and important stability and bug fixes.

From reworked class perks to expanded weapon choices and smoother progression, Patch 9.0 fine-tunes the experience for Space Marines taking on Tyranids, Chaos, and competitive battles alike.
Datavault & New Content
Patch 9.0 expands the Datavault system to make rewards and in-game lore easier to track.
- New Siege Ordeals introduced for fresh PvE challenges.
- Trygon entity added in the Tyranids tab, offering more bestiary depth.
- Datavault reward screen redesigned for improved UX and future content expansion.
These changes give players clear long-term goals and make Datavault progression more rewarding.
Major PvE Weapon Overhaul
The largest part of Patch 9.0 is the complete rework of PvE melee and firearm weapons.
- Melee Weapon Progression now follows clear rules:
- Balanced weapons = moderate speed/damage
- Fencing weapons = fastest but weakest
- Block weapons = slowest but strongest
- Relic-tier melee weapons now strictly outperform Artificer-tier weapons for clearer progression.
- Firearm Rebalance Examples:
- Bolt Rifles & Carbines: Clip size and reserve ammo increased, with improved recoil control.
- Stalker & Sniper Rifles: Headshot multiplier increased to 2.3x for higher skill reward.
- Heavy Bolters & Multi-Meltas: Reduced heat buildup and faster venting for sustained fire.
- Inferno Pistol: +15% base damage, now a dedicated crowd-control tool.
These stat changes make underused weapon versions viable, adding meaningful loadout choices for all classes.
Class Perk Reworks
Classes receive substantial perk updates to improve combat flow:
- Assault Perks:
- Winged Fury: 100% bonus melee damage when sprinting/dashing, with 7m AoE and 5s cooldown.
- Hammer of Wrath: Grants 30% ranged damage reduction and knockback immunity for 15s after Jump Pack use.
- Act of Attrition: 10% → 15% damage bonus.
- Smiting Angel: 10% → 25% damage bonus.
- Heavy Perks:
- Thermal Boost: Now grants +15% ranged damage at 50% heat or half magazine.
These perk changes make Assault and Heavy classes far more reliable, especially in high-difficulty PvE and Siege Mode runs.
Siege Mode Changes
Siege Mode now offers smoother progression, cheaper shop costs, and clearer wave scaling:
- Shop Adjustments:
- Guardian Relic: 300 → 200
- Armor Kit: 60 → 30
- Dreadnought: 1500 → 1250
- Guardsman Tier 4 & 5 cost reduced
- Difficulty & Enemy Waves:
- Guardsmen HP/Damage boosted by +50% on Normal, +100% on Hard
- Dreadnought timer increased to 5 minutes
- Wave cycles predictable: Every 3rd wave spawns 1–2 Terminus, every 5th wave spawns 2–3 Terminus
These changes make Siege Mode less random, rewarding strategic planning and resource management.
PvP & Progression Updates
Competitive players also see meaningful improvements:
- Max PvP level increased to 44 for extended progression
- Weapon pool expanded for all classes:
- Tactical: Combat Knife, Plasma Pistol, Heavy Bolt Pistol
- Assault: Power Sword, Plasma Pistol
- Sniper: Instigator Bolt Carbine, Heavy Bolt Pistol, Marksman Bolt Carbine
- Vanguard: Marksman Bolt Carbine, Heavy Bolt Pistol, Bolt Carbine
- Support: Heavy Bolt Pistol
- XP required for rewards reduced for faster progression
- Private lobby and matchmaking fixes improve online stability
This refresh makes PvP more accessible for casual players while rewarding grinders with new levels.
Combat Quality of Life
Moment-to-moment gameplay feels better thanks to QoL improvements:
- Anti-Stunlock Mechanic: Successive heavy hits reduce stun duration to 80%, then 60%.
- Assault invulnerable during ground pound landing, preventing cheap deaths.
- Improved control responsiveness and fixed stance-reset issues with Power Sword and Plasma weapons.
These changes give players more control and survivability in chaotic battles.
AI, Bug Fixes & Technical Improvements
Patch 9.0 addresses critical bugs and AI inconsistencies:
- Neurothrope beam damage fixed
- Lictor invulnerability bug resolved
- Cultist Sniper double-shot issue fixed
- Plasma Incinerator charge reset and VFX orb glitches resolved
