Nucleon Shock Cannon

One of the more powerful weapons on Cybertron, the Missile Turret (also called Nucleon Shock Cannon) is exactly what it sounds like: a turret that fires missiles. Desperate fighters can tear the turret from its base and carry it around, whereupon its ammo becomes (very) limited. Turrets feature a lock-on mechanism equivalent to the Thermo rocket launcher.
