Sandustry Mods Directory
Every mod cross-checked against Early Access compatibility. Install paths for Steam, GOG, and Game Pass, plus the de-facto Fluxloader modloader guide. Demo-era mods that broke under the EA simulation rewrite are flagged — so you do not waste time installing something that crashes on launch.
EA vs Demo Compatibility Matrix
The EA launch on August 13, 2026 shipped a complete simulation rewrite. Mods built only against the Demo's physics engine frequently crash under EA. Use this table before you install.
| Mod | Author | Version | Category | EA v0.5.6 | Demo |
|---|---|---|---|---|---|
Core Lib Required dependency for most Fluxloader mods. Install this first — without Core Lib, most other mods will not load. | Fluxloader Team | 3.1.3 | Library | ✓ Yes | ✓ Yes |
Fluxloader (Core) The modloader itself. Injects mods into the Sandustry Electron process at startup. Required to use any other mod in this directory. | Fluxloader Team | 3.x | Loader / Core | ✓ Yes | ✓ Yes |
Custom Map Loader Lets you load community-made custom maps (.json or fluxloader format). Required for any "map" category mod below. | Electric131 | 4.1.6 | Loader / Core | ✓ Yes | ✓ Yes |
Sandustry Together Online co-op multiplayer mod — experimental build. Requires corelib ^3.1.0. Known to desync on large factory builds. | darude | 0.5.0 | Multiplayer | ⚠ Exp. | ✗ No |
Creative Mode Unlocks all research, infinite resources, and a no-clip build mode. Useful for testing factory layouts before committing in survival. | Electric131 | 1.1.3 | Cheat / Sandbox | ✓ Yes | ✓ Yes |
Texture Pack Loader Load community texture packs without overwriting game files. Required for any "texturepack" mod. | Electric131 | 2.2.1 | Loader / Core | ✓ Yes | ✓ Yes |

No Fog Overlay Removes the underground fog overlay for clearer visibility during artifact hunting. | Almighty Pumpkin | 1.1.0 | Visual | ✓ Yes | ✓ Yes |
Center Cell Fix Fixes a v0.5.x regression where factory cells near the world center would not save correctly. | Almighty Pumpkin | 1.0.0 | Bug Fix | ✓ Yes | ✗ No |
Out of Bounds Patch Patches an EA-only crash triggered by items pushed outside the world bounds by launchers. | Electric131 | 1.0.0 | Bug Fix | ✓ Yes | ✗ No |
Mod Installation Paths by Platform
The #1 reason mods fail to load is wrong install path. Each platform puts Sandustry in a different directory. Fluxloader tries to auto-detect, but GOG and Game Pass often need manual configuration.
C:\Program Files (x86)\Steam\steamapps\common\Sandustry\Default Steam library. Right-click Sandustry in Steam → Manage → Browse local files to open directly.
~/Library/Application Support/Steam/steamapps/common/Sandustry/macOS Steam install. Mods go inside this folder under /mods/ (created by Fluxloader on first run).
C:\Program Files (x86)\Steam\steamapps\common\Sandustry Demo\Demo installs to a separate folder. Demo mods in the Fluxloader catalog are tagged "demo_compat: yes".
C:\GOG Games\Sandustry\GOG install path differs from Steam. Fluxloader auto-detects on first launch — if it fails, set the path manually in Fluxloader settings.
C:\XboxGames\Sandustry\Content\Game Pass version is sandboxed. Modding requires modifying Fluxloader's config to point at the sandboxed Content directory. Some mods are blocked by sandbox policies.
How to Install Sandustry Mods (Step by Step)
- 1Download Fluxloader from fluxloader.app and install it.
- 2Launch Fluxloader once — it auto-detects your Sandustry install path. If it fails on GOG/Game Pass, set the path manually in Settings.
- 3Install Core Lib (Fluxloader Team) first. Without it, most other mods will not load.
- 4Install any loaders you need: Custom Map Loader (for map mods), Texture Pack Loader (for texture mods), Skin Loader (for skins).
- 5Browse the Fluxloader catalog and click Install on any mod. Fluxloader handles the /mods/ subfolder automatically.
- 6Launch Sandustry via Fluxloader (not directly from Steam). Fluxloader injects the mods at startup.
- 7Verify mods are loaded by checking the Mods menu inside Sandustry (top-right of the main menu).
