As a member of the Rescue And Intervention Non-profit (RAIN) organization, your job is simple. You must rescue cities on the WEPA blacklist before they are punished by the world for being destructive to our irreplaceable natural resources. Ultimately, you must help reorganize cities so that they will become environmentally friendly and inspiring places to live. But it won't be easy. You will be constantly challenged by Bane Industries, one of the last corporations in the world that refuses to submit to WEPA environmental standards for process and production.
Best described as "SimCity-meets-Tetris", City Rain produces buildings that fall from the sky, which must be quickly place on a grid. Players are challenged to master the art of urban planning on the fly, requiring quick reflexes and a logical building placement that ultimately helps the community thrive and the ecology survive.
