Missile Turrets were stationary turrets that popped up from the ground when someone strayed near. They were very similar to Beams Turrets, but deadlier. You will really have to keep moving once it fires. Missile Turrets will shoot out four heat seeking rockets that will home in on you. The best way to get rid of one is to stay at a far distance once it pops out then use a long range weapon like the Fusion Rifle on it.
Missile Turrets are first seen on planet Kronos; Night Flight.
