Machine Party at a glance
Machine Party released on Steam on July 30, 2026 for Windows and SteamOS/Linux. The current Steam build supports online private rooms for two to four players, and v2.0 adds native local co-op for up to four players on one PC; public matchmaking is not built in. Check the player-limit guide or the Steam Deck guide for platform details.
If a friend cannot join, start with the online multiplayer fix. If you are planning one-screen play, see the local co-op setup for the Local menu and controller flow.
