These are the second boss in the game, but another is also encountered shortly after getting the MP50, there is a naturally spawning Devastator on an island in the Genesseret reservoir, near the facility where the armor is stored, and there is fought during the finale, and another is seen loaded onto the airship. It seems to be some sort of infantry support vehicle. It is rather like a dwarf version of the walker, it also is a "head" on legs, and appears to be a drone or perhaps even AI operated. It is black and white, with a large chain gun and a small rectangle on top, which is a missile launcher. It has a extremely simple attack pattern: It normally fires its chain fun. If the player goes into cover, it fires missiles. If the player gets close, it stomps. It turns around if the player goes behind it and exploits its main weakness, the vent on its back, but the player can run through its legs and fire at the vent again. Running on top of the mech when it is fought early in the game is not a good idea, the stomp will damage you, and without the extra armor and health gained in the late game, can kill you. With late game weapons, it can be dispatched almost as quickly as a shield soldier, for example, the inertial element kills it with a few shots into the vent.
