HRUNTING/YGGDRASIL Mark I Prototype Armor Defense System

Prototype Powered Exoskeleton

The Prototype Powered Exoskeleton is an experimental bipedal exoskeleton developed by the UNSC Marine Corps in facilities on Algolis. The armor was an earlier version of the MJOLNIR Powered Assault Armor, designed for use by the SPARTAN-IIs. However, despite its effectiveness, the idea was mainly scrapped, as the user was very vulnerable and it was too complicated for use on the limited number of Spartan-IIs. The prototype of this Exoskeleton suit was destroyed along with all of its data due to the enactment of the Cole Protocol during the Battle of Algolis.
