FOTUS-class Mjolnir

"Tested in the rough and tumble streets of downtown Kirkland, Washington."

- FOTUS armory description

The MJOLNIR Powered Assault Armor/FOTUS is a variant of the MJOLNIR Powered Assault Armor (GEN2) utilized by SPARTAN-IV supersoldiers. It appears to be based on Forerunner technology, with the helmet resembling the head of a Promethean Knight.

Behind the scenes

 * The armor can be unlocked only by purchasing a copy of the Halo 4 Limited Edition XBOX 360.
 * The FOTUS armor is presented as a metafictional joke. It is said to have been developed by 343 Industries tested in Kirkland, Washington, which is 343 Industries' hometown. The gauntlets are designed to defend against cougar attacks in the "Land of Kirk", while the FOTUS greaves earned high marks during coffee runs on rainy days. The prominent spike on top of the helmet is a reference to 343 Industries' running unicorn gag, which is also referenced in Halo: Combat Evolved Anniversary. While the FOTUS armor is presumably canon, the Armory's descriptions of the suit's components are very tongue-in-cheek and obviously not meant to be taken seriously.
 * FOTUS stands for Fist of the Unicorns. A band made up of crew members on The Pillar of Autumn.
