Terrorists are everywhere. They are even at the dock. They will use anything they can to terrorize, because that's what they are - they are terrorists. Your job is to kill as many of them as possible and bring life back to normal. Use your mouse to aim and use the left mouse button to fire your weapon. The terrorists will pop their heads out randomly, and you have to take their heads off with your weapon. But, there are dock workers and civilians walking about, so you must keep from shooting them. If you do, it's game over.
