HELLCAT-class Mjolnir

HELLCAT-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor [GEN2].

Development history
Designed using artifacts from humanity's prehistoric interstellar empire, mostly from ruins of a dead world and the vault of a shattered starship. Spartan-IIs testing the armor showed near-perfect synchronization with the armor, though compatible Spartan-IV operators required an acclimatization period and tweaks to their augmentation maintenance before deployment.

 * Helmet description: Tests with Spartan-II veterans show near-perfect synchronization with HELLCAT armor, but compatible Spartan-IV operators require an acclimatization period and tweaks to their augmentation maintenance before deployment.
 * Body description: Built of knowledge stolen from enigmatic ruins on a dead world and materials stripped from the vault of a shattered starship, the HELLCAT is both utterly alien and strangely familiar.

Production notes
Internally, Hellcat armor was known by the codename "A084", with the in-game model produced by Airborn Studios. The armor's original design was created by 343 Industries concept artist Kory Lynn Hubbel, in conjunction with fan Andrew Thivyanathan - who had won a contest with the charity Child's Play to design an armor. Thivyanathan wanted to base the armor on that worn by the ancient human soldiers, and the two worked to come up with the design seen in-game. Thivyanathan was also featured in-game as the character Andrew Thivyanathan, a de-glasser working on Meridian.
