Befitting their highly classified status as an unconventional warfare (UW) unit, Spartan: Black’s ebony armor had been created as skunkwork prototypes in a top secret parallel development lab in Seongnam, United Korea; as such, MJOLNIR: Black boasted a few variant design elements and enhancements completely different from the standard-issue combat exoskeleton. Its HUD magnification, for example, was much greater than the standard Mark V or VI, with a field of view of nearly five thousand meters. From this distance, Spartan: Black could zoom in on the support troops milling beneath the antigrav “feet” of the Beacon and see them as clearly as if they had been standing across the street.
