Hostile environment life support


The Nightfall armor is a hostile environment variant of the ODST armor developed by Cascade Stronghold Technology.[2] A variant of the armor designed for the MJOLNIR [GEN2] platform is available for use by Spartans.[3]


Compared to the similar GEN2 ODST armor, major differences include a data crystal chip port on the back of the helmet (much like those featured on the Mark V and later MJOLNIR iterations) and a camera integrated into the brim of the helmet (which consequently extends farther over the faceplate). The helmet's visor is retractable and contains a sophisticated VISR suite capable of identifying and analyzing objects in the environment.[4]

The armor is powered to some extent and is able to effectively negate the impact of a substantial fall during a deployment from a dropship, for example.[4] According to Colonel Randall Aiken of the Sedran Colonial Guard, without the hydraulics being powered up, the armor is basically just dead weight on the wearer who can move around in it, but are hampered in their movements, particularly in hostile environments when they need to move fast.[5]

Development history[edit]

Cascade Stronghold Technology, the company that ported the ODST armor to MJOLNIR Powered Assault Armor [GEN2], is also responsible for creating the MJOLNIR GEN 2 version of the Nightfall armor. The armor was built to function in extreme temperate conditions. The first models of the nightfall armor were deployed in 2551 to ONI operators and select ODST special forces units.[2]

Developed at the Special Warfare Center in Seongnam, Korea, Nightfall combines elements of standard Marine Corps body armor, ODST combat armor, and MJOLNIR.[1]


The armor is worn by Office of Naval Intelligence operatives.[4]

Spartans recruited from the Marine Corps favor the GEN2 Nightfall armor when stationed on inhospitable worlds due to its best-in-class life support.[3]

In 2556, Locke's team wore the armor during a mission to Alpha Shard in order to destroy deposits of a deadly new element. During an attack by Lekgolo worms, the team was forced to deactivate their armor's systems in order to avoid detection. At the suggestion of Colonel Randall Aiken of the Sedran Colonial Guard, the team removed and abandoned their armor as without the hydraulics and air conditioning, it was just dead weight and they could not risk reactivating it without drawing the attention of the deadly worms.[5]
