Motor Town offers three multiplayer modes.
Solo (single player)
Played offline against the local save. Property is owned permanently and progress/economy are local to that save file. No external server needed.
Host (peer-to-peer)
A player hosts a multiplayer session directly from their own PC. The world is online only while the host is online — when the host quits, the session ends.
Dedicated Server
A standalone server (Steam App ID 2223650, free for game owners) that hosts a persistent multiplayer world independent of any player's PC. Dedicated servers gate uniquely-server-side features:
Corporations — always-on company operations.
Configurable property rent timers — see rent expiry & recycling.
Admin tools — see reporting & moderation.
Player cap
The current concurrent player cap is 48, with a documented plan to raise it to 128 in the future.
