Summary
Patch 15.0 introduces significant new content and systemic rebalances to Space Marine 2. The headline addition is the introduction of Chaos forces into Siege mode, allowing players to control Heretic Astartes on the new Hive map. For PvE players, the Crucible mode offers a new level 25 endgame challenge with unique rewards.
Tactical Class & Weapon Overhaul
The Tactical class has received a comprehensive rework of its perk tree, shifting power from the Auspex Scan (which saw its team-wide damage multiplier reduced) into base weapon damage and more flexible combat options. To compensate for the Auspex adjustment, nearly every primary bolt and plasma weapon received a base damage buff. Melta weapons have been redesigned to be significantly more powerful at point-blank range but with more aggressive damage fall-off and reduced ammo capacity.
Customization & Season Pass
Wargear 2.2 introduces separate slots for tabards and cloaks, allowing for deeper customization. The update also launches the Space Wolves and Exorcists cosmetic packs for Season Pass holders, alongside new Heroic-tier weapons and armor parts unlockable via Accolades.
