HELLJUMPER-class Mjolnir

HELLJUMPER-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor [GEN2] derived from ODST armor. It is manufactured by Cascade Stronghold Technologies.

Development history
The armor is considered to be the pet project of Cascade Stronghold Technologies' current chief executive officer, a former Orbital Drop Shock Trooper.

The armor's helmet was initially created for service in the UNSC Marine Corps, though development delays kept it from consideration by the branch. However, only minor modifications were required to make the HELLJUMPER-class armor's helmet fully compatible with GEN2 Mjolnir armor.

Usage
A small number of HELLJUMPER-class prototypes have been commissioned and entered service into the Spartan branch under a research partnership between the United Nations Space Command and Cascade Stronghold Technologies. Spartans Edward Buck, Kojo Agu, and Michael Crespo used this armor during Operation: COALPEPPER in August 2555. Edward Buck would continue using the armor up to the Battle of Genesis in October 2558.

Halo 5: Guardians
Helljumper was first introduced as an armor set in Halo 5: Guardians, and the suit employed by Buck in the campaign. The Helljumper set has one alternate skin design; Feet First.
