Everyone knows that if you want to survive, you need to be tough as hell. There are no rooms for the lighthearted in a town full of gangster. They will just crush you like a flea if you are soft and take advantage of your generosity. That is why; you need to take arms and show them who is the boss around.
The game is played via mouse and you need to make sure that you kill all the gangster. Shoot them fast or they will kill you in an instant. It is better if you are going to shoot and kill them before they can even react. You can't dock in this game. You can only rely on your gun. Unlock a shotgun, when you reach a certain score in the game.
