UE4SS is a powerful tool for modding Unreal Engine games, supporting Lua scripting, C++ mods, blueprint loading, live editing, and much more. This version is a fork of the original UE4SS, maintained by the same team behind Nautilus and other core libraries for Subnautica and Subnautica: Below Zero.

How to launch:

  1. Download UE4SS for Subnautica 2;
  2. Place the archive into the \Subnautica2\Subnautica2\Binaries\Win64 folder (NOT in \Engine);
  3. Right-click the archive and select "Extract Here" (or open the archive and drag out its contents);
  4. Install mods into the \ue4ss\Mods folder;
  5. If everything is installed correctly, when you launch the game, a UE4SS.log file should appear in the \ue4ss folder. If you don't see UE4SS.log, you might just have a UE4SS file without the .log extension.
