A Slay the Spire 2 mod that increases the vanilla 4-player multiplayer lobby limit. Gather more friends and climb the Spire together!
A Slay the Spire 2 mod that lifts the vanilla 4-player multiplayer cap to 8 (configurable up to 16) and fixes the UI to handle the extra players — campfire seating, shop layout, relic screens. It uses Harmony to patch the game at runtime, so it's a reasonable example of Harmony-based modding for a Godot+C# hybrid game. The readme opens with an abandonment notice, which tells you what you need to know about its future.
The scope is tight and well-defined — it patches exactly what breaks when you add more players rather than hacking a single number. The campfire/shop/treasure layout fixes show someone actually tested beyond 4 players instead of just changing a cap constant. Cross-platform support (Windows, macOS Rosetta workaround, Linux) with documented edge cases like the TLS handshake bug and the Harmony unwind exception on Linux is more thorough than most game mods. The build toolchain (PowerShell + shell scripts, Godot .pck bundling) is scripted rather than manual.
The README explicitly states the project contains 'a large amount of AI-generated code' and is abandoned — that's a serious caveat for anyone wanting to fork and maintain it. The 8+ player cap triggers rendering errors per the readme's own notes, meaning the configurable 16-player limit is effectively a footgun. No automated tests of any kind — Harmony transpiler patches are notoriously fragile across game updates and there's no safety net. The config migration story (delete config.json manually before upgrading) is the kind of thing that will silently break someone's install.
