Deliver2Mac has begun selling downloads of Chicago 1930, the RuneSoft real-time strategy game. Players join a campaign as either the Chicago police or the Mafia, who in the former case have to protect the public and interrogate witnesses, while the latter get to fight both police and rivals, as well as hush up any bystanders. Combat requires smart tactical thinking, and can involve weapons ranging from baseball bats to through to Tommy guns. The game runs on Mac OS X 10.3.9 or later and costs $30.
