It's very dangerous to walk at night in a wrong place. Especially here, where the streets are full of criminals-hunters.
Walk carefully and quietly, so that the gangsters don't hear you or they'll cut you down. Use the controls to adjust the loudness of your steps.
Pick up the weapons on your way, protect yourself.
Find your way out, fight all the hunters that you come across. Hurry up - get the hell out before the break of dawn.
Use the arrow keys to move, SHIFT - to sneak, Z - for the action.
