From the official website:
"Crime Cities is a combination of an action game and a flight simulator set in a 3d futuristic city.
Garm Tiger, a police officer back on earth betrayed by his own people is cast into the world of crime and corruption. His destiny is purging the universe from all kinds of filth. He has to travel to the barely remembered planetary system controlled by the mafia. Unfortunately, corruption in the Pandemia system has no face so in order to deliver justice he has to become what he loathes.
The player has to complete over 100 varied missions. The single player mode offers 3 kinds of vehicles and 23 weapon types. The multiplayer mode extends the choice of vehicles to 17."
