CHALLENGER-class Mjolnir

CHALLENGER-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor (GEN2).

Specifications
Challenger armor is built on a PROTECTOR frame subjected to hundreds of additional tests and quality assurance checks. This variant also has high-performance thrusters and shield emitter arrays.

Development History
This variant has hundreds of additional tests and quality assurance checks are to minimize performance quirks that negatively impact War Games performance. The high-performance thrusters and shield emitter arrays require constant stress monitoring and adjustment to avoid critical failure during a match, much to the dismay of Infinity’s support teams.
