Use openOMSI multiplayer for your Bus Company Simulator trips. BCS/BBS chooses the trip and receives its driving data. openOMSI runs the shared world, so drivers on the same map can encounter one another.
Release candidate: 3.0.3. This candidate targets BCS 5.0.2.0 and protocol-7 openOMSI. The bundled official server is 0.2.50; the minimum official client is 0.2.48. 0.2.47 was not officially released. A complete two-PC trip remains the final gameplay check.

Read the full player and host guide
- A company invitation routes each trip to its map session. The first driver on each map hosts automatically; joining peers share that world.
- Berlin and Carrão City get separate servers and tunnels. A direct Berlin server link only points to Berlin. Use the company invitation for map routing.
- Next trip uses the native BCS 5.0.2.0 plugin/command interface. Original vendor Lua is forwarded unchanged; no BCS JAR patch is applied.
- Unmodified official server, protocol-7 private-bus adapter, player fuel restoration, fresh BCS game.log and local diagnostic ZIP.
- Windows; PT-BR, English and German; solo switch, backups and verified Cloudflare 3.x updates.
A host PC must stay on and connected while peers use its map. Missing peer buses may use stand-ins. Map/mod dependencies remain the player’s responsibility.
