Paradox Interactive and Colossal Order have just revealed how to sign up for their limited closed beta of Cities in Motion, a mass transportation simulator set across four European cities, that’s due for PC release in early 2011. The title sees players develop and operate their own public transport company building a travel network across Vienna, Berlin, Helsinki and Amsterdam, that employs 5 modes of transport, and over 30 vehicles. As each city develops and grows the player must continue to meet the ever changing transport needs of its commuters, while ensuring it remains as profitable as possible.

Sign up for the beta before October 11!
