MULTIPLAYER CURRENTLY IS NOT SUPPORTED
1. Start with the App
Multiplayer is not supported at this time. Don’t use mutliplayer with mods! This will cause “game state desync” issues.
- Open Crowd Control Desktop App
- Select Slay The Spire 2 from the game list
- Follow the Auto Setup checklist (left side of app)
The host player requires the mod and joining players require the mod for effects to trigger!
2. Test Before You Stream
- You can only test effects after pressing “Start Session” in the Crowd Control app
- Always test a few effects before going live to confirm effects trigger as expected
Skipping this step can lead to broken streams and confusion!
Modded Profile
Modding Slay the Spire 2 automatically creates a “modded profile,” separating your modded saves from vanilla gameplay. The game will detect mods on launch if you are not in an active run.
To restore your saves, follow the uninstall steps below.
Troubleshooting
- “Desync Error”:
- This is due to multiplayer and is currently not supported.
- “Awaiting connector”:
- End or complete your current run and re-launch the game.
- Use Mod Settings to enable or enable/disable the mod.
- Settings > General > Mod Settings


Mod Compatibility
- Our mod can be managed from the in-game mod manger
