Nightfall armor

The Nightfall armor is a hostile environment variant of the ODST armor worn by Office of Naval Intelligence operatives. A variant of the armor designed for the MJOLNIR [GEN2] platform is available for use by Spartans.

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

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