Patch History[edit | edit source]

Update 29.5

  • Fixed the Quassus and Gunsen gaining different Melee combo counters on first hit with the Slicing Feathers Stance. They will both have the same 3 combo counter hits now.

Hotfix 29.2.1

  • Fixed the Quassus leaving you "unarmed" after using heavy attacks.

Hotfix 29.1.1

  • Fixed issue that stopped Pressure Point and its derivatives from not applying to Quassus Heavy Attack projectiles.

Hotfix 29.0.8

  • Increased Heavy Attack projectiles from 35 to 76
    • Also fixed Quassus Heavy Attack projectiles being slowed down to 15% of their original speed after punching through an enemy.
  • Reduced horizontal spread of projectiles
    • Quassus throws 12 projectiles with a pretty wide horizontal spread, spreading the Damage across multiple targets. Individual damage was not where we wanted it. Increasing it over 100%, narrowing the spread and making sure it will hit additional targets after passing through, increases its lethality to intended levels.

Hotfix 29.0.2

  • Fixed a crash when inspecting the Quassus’ stats in the Mission Progress screen while in the Cambion Drift.

Update 29.0

  • Introduced.
