Cosmonarchy BW is a community add-on for StarCraft. A fresh strategic meta for StarCraft veterans with new units and refined macro mechanics. Use the PlayBound launcher to drop the archive into the correct StarCraft content folder, then enable the mod from the game's mod or content menu. Mods are versioned separately from the base game — match the recommended engine or client release before joining multiplayer, and keep a clean backup of your settings if you experiment with several packs at once. PlayBound only lists projects that publish redistributable archives or clear external download pages. Always read the upstream README for credits, required assets, and known incompatibilities.
Install with the PlayBound Launcher
The launcher installs this into Cosmonarchy/ for StarCraft. If the base game is missing, it will install that first.
