How does the City Transport Simulator platform work?

City Transport Simulator is the technical foundation for multiple standalone games – including CTS: Tram and CTS: Bus. Each title can be played independently. You don’t need CTS: Tram to play CTS: Bus – and vice versa.

CTS: Bus is not a DLC or add-on – it's a full-fledged standalone title with its own content, vehicles, and gameplay modes. You can start and play it entirely on its own.

If you own both games, CTS will automatically recognize it and unlock all content seamlessly. No extra steps required – just launch CTS and enjoy everything you own.

The best part: even if you only own one of the games, the city will never feel empty. In CTS: Tram, AI buses drive through the city – in CTS: Bus, AI trams are part of the environment. This ensures a vibrant and believable city at all times. Only players who own both games can drive both vehicle types.
