Cross-Platform Multiplayer

Steam and GOG players can connect to the same server.

How It Works

The server generates two invite codes:

Platform	Code Format	Connection Method
Steam	Starts with "S" (e.g., S123456789)	Steam Datagram Relay
GOG	Starts with "G" (e.g., G1234567890ABCDEF)	Galaxy P2P

Share the appropriate code with each player based on their platform. When both are available, Steam is recommended for better reliability.

Connection Reliability

Platform	Success Rate	Notes
Steam	~99%	Traffic routes through Valve's relay network
GOG	~50%	P2P connection, depends on NAT compatibility

Steam connections are more reliable because Valve's relay handles NAT traversal. GOG uses peer-to-peer which can fail with certain router configurations.

Getting Invite Codes

docker compose exec server attach-cli
# Type: info

Or use !invitecode in-game chat.

Mixed Platform Farms

Players from both platforms play together on the same farm. There are no gameplay differences between Steam and GOG players once connected.
