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 pre-ordering a copy of the Halo 4 Limited Edition XBOX 360.
 * The FOTUS armor is presented as a metafictional joke. The acronym supposedly stands for "Fist of the Unicorn(s)", which was referenced as a band made up of the crew members of the in Halo: Combat Evolved Anniversary. In the in-game description, the armor 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. 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. Presumably, the armor was reverse-engineered from Forerunner technology like the latter-released Prefect armor, possibly from Trevelyan.
