Every DEADEYE helmet incorporates a small piece of alloy from one of the ships now resting in the wreckage above Tribute's poles.
MJOLNIR Powered Assault Armor/Deadeye is a MJOLNIR [GEN2] variant used by SPARTAN-IV personnel. It is manufactured by Hannibal Weapon Systems and was originally tested in the vast ship graveyards hanging in the orbital plane above Tribute's northern pole and later at Kotka, Pori, New Carthage. It is optimized for extraordinarily long-range target purging.
- The Deadeye helmet was a Halo 4 pre-order bonus from Best Buy and Play.com.
- In Halo 5: Guardians, Deadeye body armor is the same as FOTUS body armor.
