Private Anderson arrived on the ship after fleeing from the USS Odobenus orbital platform, only to find the Xenomorph infestation that had started at the Weyland-Yutani research facility on LV-426 had somehow spread to the Tyrargo as well. After fighting his way through the ship, killing a Predator, several Praetorians, a Predalien and a multitude of Warriors, Weyland-Yutani elected to leave Anderson to die on the Tyrargo, thanking him for his services. However, Anderson's commander opened an escape route for him, allowing him to flee to a large hangar at the bottom of the ship where he faced the Xenomorph Queen. After expelling the Queen into space, Anderson's fate (and that of the Tyrargo itself) is not known.
