Use the gamemode’s internal folder name, rather than its Workshop title. Check its author’s instructions and required addons.
Install the gamemode
- For a Workshop gamemode, add it and its required items to your server’s collection.
- For a manual install, upload its folder to garrysmod/gamemodes. Avoid nesting an extra copy of the folder.
- Find the internal name in the folder or the author’s instructions. Choose a map that supports it.
- If you are replacing a gamemode that stores player progress, back up its data first.

└── your_gamemode/
└── [the gamemode files]Set the gamemode
In Startup, set Gamemode to its internal name, such as sandbox. Set Map to the map filename without .bsp. Restart, check Console and join.
The Gamemode and Map fields control what loads when the server starts. If a field is locked or missing, contact Konnect support.
If the wrong mode loads
Check the internal name, dependencies and Console errors. Return to the previous gamemode and map while fixing the install if needed.
For Workshop setup, see adding a Workshop collection. For maps, see changing your GMod map. Compare GMod hosting plans.
Troubleshooting checks
| What you see | What to check |
|---|---|
| Gamemode is installed but Sandbox starts | Check the internal folder name in Startup. A Workshop collection title is not the gamemode identifier. |
| Gamemode loads but the map is unsuitable | Choose a map built for that mode and install its required content before testing again. |
