📋 About This Mod
->
Looking for lua scripts, see:
AMUMSS LUA MOD SCRIPT ARCHIVE <-AMUMSS is NOT a mod manager, nor can it be used as such. It is a script processor.
AMUMSS does NOT need updating to continue working when NMS updates.
When the tool MBINCompiler.exe is updated, AMUMSS will download it automatically.
AMUMSS will auto-update itself (when allowed), if a new version is available (Just execute BUILDMOD.bat as usual and read simple instructions)
-
[]The tools MBINCompiler/libMBIN are auto-updated by AMUMSS.[/]
[]Scripts are NEVER updated by AMUMSS, you are responsible for using updated scripts, when they need to be.[/]
Questions will be answered if asked in NMS Discord: here https://discord.gg/22ZAU9H
IMPORTANT NOTES:
-
[]This tool works as long as MBINCompiler can compile/decompile the MBIN touched by the scripts[/]
[]NEW version does requires . NET 8 Desktop Runtime x64 to be installed (a MBINCompiler.exe requirement) It will attempt to auto-install.[/]
[]Note: Sometimes, your anti-virus may detect some component of AMUMSS and block/quarantine it. Be assure it is not a virus but its behavior may be interpreted as such by some anti-virus. Please make sure to create an exception in your anti-virus when this happens. Also a reboot may be required as some anti-virus do not correctly register the exception when created.[/]

Get the latest release from AMUMSS latest releases on Github Link De-compress the zip file to its own folder (like C:\AMUMSS) Making the path to AMUMSS main folder short helps prevent bumping against windows path length limit (in rare cases) No accented or special characters in the path
Always extract to a new folder on any drive, never in any System, Documents or game folder
Create an exception to AMUMSS main folder BEFORE executing anything
If the cmd windows closes immediately (or is blank) when double-clicking BUILDMOD. BAT:
if you are on windows 7. Try making '-UseColors N' in BUILDMOD_AUTO.bat and use it instead of BUILDMOD.bat

AMUMSS is a script processor for No Man's Sky modding, not a mod manager. It auto-updates itself and the MBINCompiler tool, and includes GUI apps for exploring game files and managing mod scripts. Requires .NET 8 Desktop Runtime and works with NMS updates without needing manual updates.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust with 3,211 endorsements and over 102k downloads
- Auto-updates core tools, so you don't have to manually track MBINCompiler releases
- Bundles three useful utilities (NMSPE, AMM, MFM) for exploring and managing mod files
⚠️ Cons
- Not a mod manager—if you're expecting drag-and-drop mod installation, this isn't it
- Anti-virus may flag components; you'll need to create exceptions and possibly reboot
- Scripts are not auto-updated—you must manually keep your mod scripts current
For No Man's Sky modders who want to build or process mod scripts with a tool that stays current with game updates. If you're a player just installing mods, skip this—you need a mod manager instead. If you're a mod author or tinkerer, this is essential.
💡 Beginner Tips
- Make sure .NET 8 Desktop Runtime is installed before running AMUMSS; it tries to auto-install but manual install is safer.
- Add an exception for AMUMSS in your anti-virus before first run to avoid quarantine issues.
- Join the NMS Discord (linked in the description) for script support and updates—scripts are community-maintained.
