Patch notes

Economy & Balance Changes:

  • The number of Corrupted Items that spawn during a Corrupted Crisis from the Crisis Board now scales with Threat level:

    • Easy - 1 Corrupted Item

    • Normal - 2 Corrupted Items

    • Hard/Extreme - 3 Corrupted Items

  • Banishing a Corrupted Item with the Neutralizer (or Black Rock Rounds) now always drops Trace.

  • Increased Trace drop chance and amounts from Powerful Enemies on higher Threat Levels:

    • Hard 20% (was 10%)

    • Extreme 40% (was 10%)

    • Trace drops now yield 1-2 Trace instead of always 1.

  • Adjusted enemy spawn rates during 'Survive the Hiss' and 'Recover' objectives on Hard and Extreme Threat Levels to be less... endless.

Achievements/Trophies:

  • The OSHA Compliant can now consistently be unlocked by completing any Corrupted Crisis on Hard or Extreme Threat Level with no one downed.

    • NoteThe in-game description still lists "Corruption Level 3" as a requirement. This text issue will be fixed in a future update.

Bug Fixes:

  • Fixed an issue where the BOOMbox sometimes failed to be placed or appeared in the wrong location.

  • Fixed an issue where the Experimental Amplification Gun Mod could damage the player when shooting at long range

    • Note: The Mod still causes self-damage at point-blank range, as intended

  • Fixed an issue in Outbreak where barrels could be ejected from the Poison Mixer if two correct ones were inserted consecutively

  • Various crash fixes and stability improvements

Localization Fixes:

  • Added missing subtitles for the Lab Rat Voice Pack

  • Various localization improvements across multiple languages

Miscellaneous:

  • Updated the visual design on emitter plates in Frequency Shift

Already fixed in 1.6.3 (but previously undocumented):

  • Players now always start the Tutorial without equipped Perks or Gun Mods, regardless of their current loadout

  • Fixed an issue in Outbreak where repairing chemical sprayers before loading the correct barrels into the Poison Mixer could break the objective.
