CYPHER-class Mjolnir

CYPHER-class Mjolnir is a MJOLNIR armor variant designed by Imbrium Machine Complex.

Development history
Supposedly a pilot program, industrial espionage revealed the CYPHER actually entered mass production in early 2557. This discrepancy has prompted ONI to begin probing IMC's shadowy Io Design Lab. Regardless this suit is not even the most secret of the Io Design Lab's products.

Usage
Spartan Tom-B292 used the helmet of this armor in 2558.

Halo 5: Guardians
Cypher was first introduced as an armor set in Halo 5: Guardians. The suit is not a fully-original design, and employs several Halo 4 armor pieces including the Scout shoulders, Inner-plated forearms and Outer-plated legs. The Cypher set has two alternate skin designs; Copiale and Voynich.

Trivia
The Copiale and Voynich skins are both named after famous coded manuscripts.
