Hotfix Patch Notes | Chemical Leak - Sept. 11

Greetings Reagents,

We have released a new hotfix patch to address the following issues:

  • Escalation: Removed Permanent Damage and No Revive from the Ultra II variator in Escalation. We plan to revisit these modifiers later as part of a broader rebalance of the Escalation flow and difficulty curve.
  • Fixed an issue where the Kress Twins document could be acquired outside of the Fund the Campaign MK-Challenge.
  • Fixed an issue where audio was missing from shuttle videos during shuttle sequences on console.
  • Fixed and issue where it was possible to get stuck in the main menu/loading screen.
  • Fixed input binding for players using AZERTY keyboards.

Feel free to join our official 18+ Outlast Discord Server and open a '/ticket' to speak directly with our support team about any issues you encounter in-game, and you can fill out our General Feedback Survey here.

We will see you in the Sleep Room!
