PREFECT-class Mjolnir

PREFECT-class Mjolnir is a variant of the MJOLNIR [GEN2]. It is reverse-engineered from the personal armor worn by Forerunner Prefects.

Development history
Research on the Forerunner shield world now called Trevelyan has cultivated numerous findings for the Office of Naval Intelligence. One of the most practical has been the discovery of a native armor system utilized by Forerunner Prefects late in their civilization's history. The Watershed Division leveraged local Huragok to reverse-engineer the original designs, grafting the abandoned armor system into baseline Mjolnir standards for Spartan-IV use. It was tested at Denegroth, West Conamara, on Europa.

Halo 4
The full set of Prefect armor is available as an armor permutation in Halo 4 as part of the Infinity Armor Pack.
 * Description: A handful of critical discoveries have led to this extraordinary hybridization of human and Forerunner technology.

Production notes

 * The Prefect variant seems to have been based on a Forerunner combat skin depicted in a piece of Halo 3 concept art by Isaac Hannaford.
