LOCUS-class Mjolnir

LOCUS-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor [GEN2] manufactured by Lethbridge Industrial.

Specifications
The LOCUS helmet has a heavily armored case-locked visor system that relies on multiple visual feeds. It also has an interlocking helmet soft-mesh loosely based on Covenant armor technology, and R4-100 dial audio sensors used for noise tracking.

Development history
The Locus variant was manufactured by Lethbridge Industrial. Tested at the Lethbridge Combat Fields, the armor system is a contemporary stealth kit conceived specifically for tactical and strategic infiltration with focus on survivability and durability. Despite its exotic design, the primary differential from similar systems is its incredible durability in the field.

Lethbridge also tested the armor for both resiliency and its attention to stealth and anti-security measures outside the megacity of Lethbridge on Concord in a number of heavily secured facilities lying across Corsica's hardscrabble northern outskirts. These tests confirmed that Locus was fully able to survive extreme opposition and firepower.

Usage
Most operators choose this suit due to its resiliency.

 * The body of the Locus armor in Halo 5: Guardians is the same as the Aviator armor.
 * The head of a Hive Thrall (an enemy from Bungie's game Destiny), bears a striking resemblance to the Locus armor's helmet.
