Hosting a game

From the main menu, choose Online → Host. Pick the closest region; the game uses your platform's native invite system on top of its own room-ID layer.

Joining a game

Two ways: (1) accept the platform invite, or (2) use a friend's room ID under Online → Join. Room IDs are six characters, case-insensitive.

Cross-play

Cross-platform play is supported between Steam, PS5, and Xbox Series X|S. You can mix platforms in the same lobby.

Common setup pitfalls

Most "can't connect" reports are NAT issues — enable UPnP on your router, or forward the platform's required ports. The wiki's multiplayer hub has the current port list.
