Your object in this game is to stay alive as long as posibble and earn as much points as you can by shooting enemy soldiers, helicopters and bombers. Be sure to gather the crates to get ammo and health and avoid explosions and enemy bullets. Use "A", "S", "D", "W" KEYS to move around. Hit "E" KEY to throw grenade and hit "R" KEY to throw proximity mine. Press SPACEBAR to jump (double tap to double dum). And press LEFT CTRL to crouch (provides better aiming). Hit "1", "2", "3", KEYS to change firing mode. Good luck!
