The Voltigore is a very large alien from an unknown dimension. It attacks by swiping its claws when in melee range, and can attack with a purple electric ball at range. When killed, it will self-destruct in a big acid shower, which will poison anyone caught within.
Because of its size and high health, it takes longer to kill than most standard enemies.
