Unlimited Multiplayer - Ignore Modlist Mismatch

🎮 **Make your "Slay the Spire 2" multiplayer experience more free! **

This mod is designed to solve connection problems caused by different mod lists in multiplayer, allowing you and your friends to play together even if you have different mods installed!

---

✨ Core Functions

  • **Ignore mod list mismatch errors**: Enabled by default. Errors caused by UI related modules can be ignored to make the connection smoother.
  • **Selectively ignore version mismatch**: This feature is turned off by default to ensure synchronization of game data and logic. You can turn it on manually if needed.

⚙️ How to use

  • **Installation**: Extract the downloaded compressed package to the `Slay the Spire 2\mods` directory.

The final file path should look like:

  • `Slay the Spire 2\mods\UnlimitedMultiplayer\UnlimitedMultiplayer.dll`
  • `Slay the Spire 2\mods\UnlimitedMultiplayer\UnlimitedMultiplayer.pck`
  • **Enable version mismatch ignore (optional)**:
  • Open the `compatibility_config.json` file in the mod folder.
  • Change all `false` values ​​in the file to `true` to enable this feature.

⚠️ IMPORTANT NOTES

  • **Ignore the risk of version mismatch**: If you ignore the version mismatch error, it may cause the game data to be out of sync. For example, you install a mod that adds new relics, but other players don't. In this case, due to different random sequences, you may encounter data out-of-sync errors, resulting in disconnection.
  • **Author's Recommendation**: Ignoring version mismatch errors may not make much sense. Turning this feature off by default is for security reasons. Please open with caution.

💡 Usage suggestions

  • It is recommended to use it online with familiar friends and communicate in advance about the modules installed by each other to reduce mismatches.
  • Mainly used to resolve UI, texture and other module conflicts that do not affect the core game logic.
  • For modules that add new cards, characters, relics, etc., it is strongly recommended that all online players keep the module list consistent.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
