Defense Unit
Creature Guide
MechanicalOverview
The Defense Unit, also known as the End Tank, is a mechanical creature in ARK: Survival Evolved. Resembling a cross between a pill bug and the Droideka from Star Wars, these rolling mechanoids serve as guardians in various locations. They are primarily found as minions defending the Overseer in the Tek Cave, roaming the Lunar biome in Genesis: Part 1, and defending the Sanctuary in Extinction. While untameable, they can be force-tamed and ridden. They run on Element and drop valuable resources including Element, Electronics, and Scrap Metal.
