• A Mac. Intel and Apple Silicon both work; on Apple Silicon it runs through Rosetta. There is no Windows or Linux version yet.
• FTL: Advanced Edition version 1.6.13. It is built and tested against the Steam copy; a GOG copy has not been tested.
• A network that allows outgoing UDP on port 27888. The match server is in Europe; the further away you are, the more delay you will have.

No game content is shipped: the installer patches the copy of FTL you already own. Starting FTL from Steam still runs normal FTL; the mod only runs through the FTL Multiplayer launcher.

To uninstall, open Terminal, drag install.command into the window, type a space and --uninstall, then press return. It restores the game data and removes the engine and the launcher.
