Under the approaching cover of darkness, the enemy makes an attempt to infiltrate your base. Heavily armed and ready to kill, you need to choose your weapon and shoot as many as you can. Use the mobile keypad or Joystick to move your gun sight and press 5 / joystick to fire. Press 0 to toggle between guns. Shoot the enemy guns that float up for extra ammo and shoot the clock that floats up for a time bonus.
