GUNGNIR armor was produced as part of Project GUNGNIR and is one of the few variants to be paired with a specific weapon or vehicle, in this case the Spartan Laser. It uses Wyrd III synchronized optimization, a modification of existing Mjolnir sighting and target-tracking technology, to seamlessly tether the armor wearer to the Spartan Laser's full functionality. The effect improves the wearer's target awareness and firing effectiveness, especially while in motion.
GUNGNIR armor was first tested at the Rajtom Facility and later manufactured by Misriah Armory. Some of its armor components, including the shoulders and knee guards, are also utilized by the UNSC Army and the UNSC Marine Corps.
Early concept art of Jun-A266 shows him wearing an initial model of the GUNGNIR helmet.
On Long Night of Solace, when Jorge-052 throws the player out of the Corvette, if you are wearing the GUNGNIR knee guards and you look at the right time, you can see the knee guards floating above your knee without being attached to them.
Changing the visor color will change the color of the camera's lens.
