Be a hit man and complete each mission! You're hired by Harold, a wealthy man engaged in illegal activities, to eliminate those who are inimical to his interests. You're also to take different missions from his friends or associates. Complete your mission and earn cash from it. Remember, you're not the bad guy, nor the good one. It's just your means of living.
Read each mission carefully and undertake them with utmost care. Be patient in identifying the assigned targets; you just can't afford killing persons who are not involved. Use mouse to aim at target and left click to shoot. Use also keys "A," "S," "D" or "F" whichever is convenient for you when sniping.
