Another PC game has started its own beta test today. This time its Cities in Motion, the upcoming transport-city sim game from developer Colossal Order and publisher Paradox Interactive. The beta client, which can be downloaded via Paradox's web site, allows players to check out Vienna, one of the four cities in the full version of the game. The beta can be played in sandbox mode or with one scenario, Part With Petrol. The open beta will continue through February 20.

The full and final version of Cities in Motion, which contains four cities ( Vienna, Helsinki, Berlin and Amsterdam) and a 12 scenario campaign as well as the sanbox mode, will be released later this quarter.
