Giant Whip Spiders are bio-weapons engineered by Alex Wesker's laboratory on Sushestvovanie Island. Derived from a species of whip spider (order: "Amblypygi"), they were not native to the island and their entire Sushestvovanian population was purposely transplanted from the tropics for research reasons.[excerpt 1]
