Check Out The Demo For Omerta: City Of Gangsters
Omerta: City of Gangsters is kind of a strange sell, which is why developer Kalypso Media is offering a demo. It's from the creators of the Tropico 4, and casts 1920's gangster culture into a strategy game.
The game is coming to Xbox 360 and PC, but the demo is only available for the latter at the moment. Any of the links below should get to a place where you can start downloading it.
