Mark VI Armor

To earn this iconic piece of armor, made famous by Halo 3’s campaign, you’ll need to earn the “Cairo Station” achievement in Halo: Master Chief Collection. This achievement can be acquired by completing the Cairo Station mission in Halo 2.


The FOTUS is a variant of the MJOLNIR (GEN2) which is utilized by SPARTAN-IVs. FOTUS is an acronym for "Fist of the Unicorns", which is why there's a protruding horn coming out from the top of this armor set's helmet. In order to receive the complete FOTUS Armor Set, you'll need to purchase the Halo 5: Guardians Limited Edition 1TB Xbox One Bundle. The bundle also includes the Vanguard Emblem.
