Anti-Aircraft Gun

Anti-Aircraft Guns are counterparts of the M2 Gun. They shoot missiles instead of fire. They cannot shoot upward, so they must tilt their gun down and not shoot until their target is at a possible angle to shoot. Anti-Aircraft Guns only appear in the mission Cripple Outpost Island, Aeorodrome Island.

Trivia

 * If you get close to Anti-Aircraft Guns that you are touching the guns, the missile will not affect you.
