DEADEYE-class Mjolnir

Deadeye redirects here. For the Halo Infinite achievement, see Deadeye (Halo Infinite achievement).

DEADEYE-class Mjolnir is a variant of MJOLNIR GEN2 manufactured by Hannibal Weapon Systems.

Design details
The suits are tailored to Spartan snipers, fitted with emissions cloaking, heavy-duty waste recycling, and redundant rebreathers for extended combat excursions in any environment. While designed for extreme-range operations the suit still is functional in both mid and close range. Deadeye can be optimized for extreme long-range target purging for the extreme end of sniper-oriented Spartan armor. With the smart-linked VISR software with movement-distance calibration, Deadeye has been updated to assist snipers at ranges that greatly exceed traditional firing accuracy.

The helmet has an enclosed PZ-238 rebreather system. The VISR has a point-isolated, VISR focal software used for extreme-range targeting. All Deadeye helmets also have a small piece of alloy from ships resting in the wreckage above Tribute's poles.

Development history
Testing on an early prototype of the DEADEYE suit was done on ANVIL Station in conjunction with Sangheili Rangers of the Swords of Sanghelios. These tests aimed to improve the suit's stealth capabilities.

The Deadeye variant's final production run was manufactured by Hannibal Weapon Systems. It was originally tested in Tribute's ship graveyard in Tribute's northern pole, and was designed for use by experienced Spartan marksmen. During the testing the Spartans were placed in zero-gravity to affect long-range combat against exoatmospheric drones hidden among the wreckage.

At some point in 2558, Spartan Kojo Agu tested another Deadeye prototype during a counter-piracy operation on Concord.

Usage
Although Deadeye is rare in the field, the armor is highly regarded by its advocates.

Halo 3 MCC
In the Halo: The Master Chief Collection version of Halo 3, the Deadeye variant was added as part of Season 5: Anvil content. With the updated Halo 3 armor customization options, the players can now fit their Spartan with Deadeye helmet, chest, shoulders and legs. The description of the armor pieces are the same for every set.

Halo 4
The Deadeye helmet was first introduced into the Halo games as a helmet in Halo 4.

Halo 5: Guardians
The Deadeye returns in Halo 5: Guardians. The helmet and body armor are unlockable as armor permutations through the Requisition system. The body armor employs the full FOTUS set, including the body, shoulders, forearms, and legs.
