Gang War is a 3D gang simulation game. The game has both strategic and action elements - you fight for control over a city with up to 6 other gangs. Importing drugs, extortion, robbery, and other methods allow you to get money, which you can use to expand your gang, or buy new guns and cars. At any point in time, you can take control of any of your gang members, and the game changes from a strategy game, to an action game where you're free to do anything that you want from getting in vehicles to mugging people.
No, it is not out yet, but you can register to the forums, and send an email to the programmer/developer to "try" and get into the beta. It's not 100 percent that you'll get in. This game looks like it's going to come out very well.
