Defense Unit — Detailed Guide
The Defense Unit is a mechanical guardian that runs on 
Element. It defends the 
Overseer in his arena and also roams parts of Extinction and Genesis, so it matters both in a boss fight and as a farm target for Element.
Where to find it
- Overseer Arena: reached through the Ascension Terminal in the Tek Cave on The Island.
- Extinction: roams Sanctuary, where its malfunctioning AI attacks wild creatures, players and tames.
- Genesis: roams the Lunar biome of Part 1. A Malfunctioned variant appears in Part 2 missions.
How to get one
It cannot be tamed, ridden or bred, and it is immune to torpor. In ASA data it appears as End Boss Tank (Beta).
Tips
- Movement: it rolls into a ball to close in and cannot attack while rolling, then uncurls to slash with its claws.
- Approach: kill it quickly with rifles, rocket launchers or tames with area attacks, backing away as you shoot.
- Drops: Element,
Element Dust, 
Electronics, 
Oil and 
Scrap Metal. In the Overseer Arena the corpse cannot be harvested.
