The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.

General Information

All mods are Unreal Engine 4 .pak files. The .pak file format is used by the Unreal Engine for storing large amounts of data in a compact space. When placed into the %localappdata%\Astro\Saved\Paks directory, these .pak files are loaded by Astroneer as patches, or partial replacements, of the main game assets found in the Astro-WindowsNoEditor.pak file.
