Responding to a distress signal, Wolf arrived on Earth, discovering the remains of a crashed Yautja Scout Ship and its dead crew. Accessing the Bio-Mask recording of one of his dead brethren, Wolf discovered the existence of the Predalien and several Facehuggers that had escaped the crash. Armed with two Shurikens, Wristblades, Dissolving Liquid, which appears to enzymatically destroy biomass, and an extra Plasmacaster, Wolf used the Self-Destruct Device on his backpack to destroy the ship and began the pursuit of the Xenomorphs.
