Historical Sandustry Demo Modding Guide Archive

Historical Demo Archive

This page preserves older Sandustry Demo modding notes for players checking legacy saves, old videos, or archived mod posts. It is not the primary install guide for the current Early Access build.

For current Workshop, mod branch, and Early Access compatibility checks, start with the Sandustry Mods Guide. As of the September 3, 2026 v0.5.6 update, the official changelog says the mods branch is also on 0.5.6, so old Demo paths and loader behavior should be treated as historical unless a mod author explicitly updates them.

Why Demo Modding Mattered

Getting Started: Prerequisites and Community Resources

Before diving into file paths and downloads, let's cover what you'll need and where to find help if something goes sideways.

What You Need Before You Begin

Community Hubs for Troubleshooting

Community reports consistently point to three main hubs where modders share updates, troubleshoot issues, and post new content:

• Sandustry Discord Server - The primary hub for mod downloads, loader updates, and direct developer interaction. You can join through the link on the official website or via the in-game menu.
• Sandustry Reddit - Great for broader discussions, mod recommendations, and showcasing custom map creations.
• Sandustry Wiki - A growing resource for documentation on mod APIs, map formats, and gameplay mechanics.

Step-by-Step Sandustry Modding Guide: Installing the Mod Loader

The Demo-era mod loader was the foundation of older custom files and modifications. These steps are retained for archive context; for an active Early Access install, verify the current loader, branch, and Workshop instructions first.

Step 1: Join the Discord and Locate the Mod Loader

Head to the official Sandustry website and click the Discord button, or use the in-game link to join the server. Once inside, scroll down to the mod forum channel and look for the pinned post titled "mod loader." That post contains a direct link to the mod loader's GitHub repository.

Step 2: Download and Place the Executable

On the historical GitHub page, the download link was usually named mod loader.exe. For Demo builds, players placed this file directly into the Sandustry demo installation folder.

Archive note: Do not place an old Demo mod loader.exe into the current Early Access folder unless the author has confirmed compatibility with your exact game version.

Step 3: Initialize the Mod Loader

In the Demo-era workflow, running mod loader.exe once caused it to briefly open and close. That initial run generated two critical items inside the Sandustry folder:

• A new folder named mods – This is where all your mod files go.
• A new configuration file – This controls mod loader settings and map selection.

Once these appeared, the Demo install was ready for compatible Demo mods.

Installing Custom Maps in Sandustry

Custom maps are one of the most popular reasons players seek out a Sandustry modding guide. They offer fresh terrain, unique challenges, and creative layouts that the demo's default maps can't match.

Step 1: Download the Custom Map Loader

Return to the Sandustry Discord mod forum and find the post for the custom map loader mod. Be sure to read the instructions in the post carefully—community reports indicate that skipping this step leads to common setup errors. Download the file provided.

Step 2: Place It in the Mods Folder

Copy the downloaded custom map loader file and paste it directly into the mods folder that was generated in the previous section.

Step 3: Download and Install a Custom Map

Troubleshooting Custom Maps

If your custom map doesn't appear in the dropdown menu, check the following:

• The map folder is placed inside mods\Maps, not directly in mods.
• The map folder structure matches what the map loader documentation specifies.
• You've restarted the mod loader after adding new files.
• The map file isn't corrupted—try re-downloading from the original source.

Installing Gameplay Mods: Beyond Custom Maps

Custom maps are just the beginning. This Sandustry modding guide also covers gameplay mods that alter mechanics, unlock content, and change how you experience Sandustry entirely.

Example: Installing the "New Game+" Mod

One popular community mod is called "New Game+," which unlocks all in-game content from the moment you start a new save. Here's how to install it:

1. Find the mod post in the Sandustry Discord mod forum.
2. Download the latest version of the mod file.
3. Copy the downloaded file.
4. Paste it into your mods folder alongside the custom map loader.
5. Launch the game through mod loader.exe.
6. Start a new game; all content will be unlocked immediately.

Types of Mods Available

Based on community reports and Discord activity, here's a breakdown of common mod categories:

Best Practices for Sandustry Modding

Following a few key practices will keep your modded game stable and enjoyable.

Keep Your Mods Organized

Common Issues and Quick Fixes

• Mod loader won't open: Ensure it's in the correct Sandustry demo folder, not a subfolder.
• Game crashes on startup: A mod file may be corrupted or incompatible. Remove the most recently added mod and try again.
• Custom map won't load: Verify the map folder is in mods\Maps and that the custom map loader mod is installed.
• Mods not appearing in-game: Make sure you're launching through mod loader.exe, not the standard game executable.

Why This Archive Still Matters

The Sandustry demo was intentionally limited, giving players a taste of the Early Access direction. The modding community turned that demo into a platform for experimentation. These notes help explain older references to:

• Dozens of community-created maps with unique layouts and challenges.
• Gameplay mods that remove demo restrictions and unlock full content.
• Quality-of-life improvements that make the demo feel polished and complete.
• A direct pipeline to the active Sandustry community for support and new content.

Treat claims about Demo playtime, unlocks, and loaders as historical context unless a mod page has been updated for Early Access.

FAQ: Sandustry Modding Guide

Is modding the Sandustry demo safe?

Do not assume a Demo mod is safe or compatible with Early Access just because it worked in old builds. Download from the current Workshop, official Discord posts, or the author's GitHub, then back up saves before testing.

Do I need to launch the game differently after installing mods?

Yes. After following this Sandustry modding guide, always launch the game through mod loader.exe rather than the standard Steam shortcut. The mod loader handles file injection and map selection before the game starts.

Can I use multiple mods at the same time?

Absolutely. You can stack custom maps, gameplay mods, and quality-of-life mods together in the mods folder. Just be aware that some mods may conflict with each other, so install them one at a time and test after each addition.

Where can I find new mods and custom maps?

The Sandustry Discord mod forum is the primary source for new content. You can also check the Sandustry Reddit and Wiki for community recommendations and mod showcases. New mods are posted regularly as the community grows.

Will these Demo mods work in Early Access?

Only if the author has updated the mod for the current Early Access branch or the current mods branch. Demo compatibility does not prove v0.5.6 compatibility.
