WSA2 Tarantula

The first boss fought in the game, but like most bosses, appears in a few locations throughout the game. It is literally a giant mechanical spider with guns. Its actual military role is unclear, as both it and the walker seem to be heavy vehicles that are sort of tank equivalents. It might be a sort of medium tank, or maybe Walkers are reserved for more high priority missions. It certainly seems to be more rugged and ally terrain compared to the walker. It has a single red eye with four main guns around it, and on the "abdomen" there is a array of missile launchers. Unlike the Devastator and Walker, it is definitely crewed, a coughing crewmen will pop out of a hatch shortly after it is first fought. When you first fight it, you need to throw grenades under it, as it broke open gas pipes when it came into the room. It just fires its cannons and lunges closer to the room you got the grenades in if you retreat inside it. The next time you fight it, it exclusively uses its missiles, and you need to trick it into firing at pipes, flooding the room with water and destroying itself. When fought later as a mini boss and in the finale, it uses both its missiles and cannons, alternating between the two.
