The patch is now available to download and is accessible to all platforms. Despite the update having relatively fewer changes, it is rather a large one in terms of its size. The latest patch weighs 12.8 GB on PlayStation and 13 GB for Steam users. Following are the latest fixes.


  • Fixed an issue related to ray tracing which caused crashes.

The issue was reported multiple times on Steam Community by PC players. The game crashed on startup and a UE screen popped up. Despite trying basic fixes, the issue persisted. You would only get rid of the issue with ray tracing disabled. However, thanks to the Striking Distance team the issue has been officially addressed and fixed.


  • Fixed an issue where users could not obtain an unreachable audio log in Tower.

The Tower is the eighth chapter in the game and concludes the story of Jacob and Dani. It comprises of total 4 audio logs. However, if you were having an issue with obtaining the audio logs in Tower, it has been fixed in the current update.
