Abiotic Factor Hotfix v1.3.0 Patch Notes (6th May 2026)

Greetings, Pest tamers!

We’ve released a hotfix that addresses a bunch of issues.

Please remove your mods before updating as they may cause crashes. If you are experiencing crashes or other issues and have any third-party mods installed (such as those found at NexusMods), please try uninstalling the mods before attempting to run the game again.

You may want to completely clear your files and reinstall the game, as there’s been cases where an uninstalled mod still leaves some sneaky files behind.

Please update your game and servers when you get a moment away from scientific study. If you’re on Steam and don't receive an update, verify your game files. Below you can see a list of all the various versions numbers, depending on your platform.

Platform	Version	Build ID
Steam	1.3.0.25870	23072293
PlayStation 5	1.3.0.25870	01.003.001
Xbox Series X, Series S, & PC App	1.3.0.25870	1.3.25870.0

• Fixed the duplication issue with Power Chairs & Office Chairs.
