In Ammo Ambush game enemy forces are trying to break through your defence. And your objective is to hold your position as long as possible. Use YOUR MOUSE to aim and hold LEFT MOUSE BUTTON to shoot. Press "A" KEY for machine gun, "S" KEY for bazooka, "D" KEY for minefield and "F" KEY for air strike. Don't use the minefield too often, because the enemy becomes stronger. The more enemies and choppers you shoot, the longer you will hold your position. If the enemy is too close blow up the minefield. Call the air strike if you think you are lost, it will end the game, but you will get 20 bonus points. Good luck!
