EVA-class Mjolnir

The MJOLNIR Powered Assault Armor/V variant, more commonly known as Extra-Vehicular Activity Armor and usually referred to by the acronym EVA Armor, is a type of United Nations Space Command body armor. The EVA armor is a variant of the standard MJOLNIR Powered Assault Armor that specialized to improve survivability of Spartans when performing extra-vehicular activity in vacuum.

Development and history
The MJOLNIR/V variant was developed and tested at a UNSC Low/Zero Gravity Testing Facility facility in Lister, Aigburth on Ganymede, integrating feedback gathered from the Summa Deep Space Incident. The V variant for the Mark IV still required a T-PACK for maneuvering in zero gravity. The Mark VI MJOLNIR/V variant focuses on increasing exo-atmospheric endurance and improving mobility in zero gravity without the original use of back thrusters.

Helmet



 * Base price: 30,000 cR, Major
 * [C] price:
 * CNM price:
 * UA/HUL[3] price:

The Mk. V variant features a large visor. It bears a striking visual similarity to the SPI helmet. A second EVA helmet, EVA [C], has a skull pattern engraved on the visor. The [C] likely stands for "Custom" or "Carved".

Two upgrades are available for the helmet, the first adds a Command Network Module on the left side (CNM), and the second adds an Up-Armor plate with a Hardened Uplink Module-3rd Generation on the right side (UA/HUL[3]).

Two upgrades are available for the [C] variant of the helmet as well, the first adds a Hardened Uplink Module on the right side (incorrectly called CNM, should be designated HUL), and the second adds an Up-Armor plate with a Hardened Uplink Module on the right side (incorrectly called HUL[3], should be UA/HUL). These errors likely have something to do with the [C] variant's attachments having the same names and descriptions as the standard variant.

Shoulder pauldron

 * Price: 3,000 cR, Corporal

The shoulder pauldrons are large and bulky, several inches thick. The attachments on the sides of the pauldrons found in Halo 3 appear to be built into them, instead of hanging out.

Unlock: Unlock Campaign Complete: Normal achievement.

The EVA armor's helmet is aesthetically similar to the Semi Powered Infiltration (or SPI) armor's helmet. The visor is smaller than the Mark V variant. However, the rim from the jaw down to the chin is thinner, including the breathers, and the back of the head has a quarter-sphere shape. The helmet is also much more rounded than the SPI helmet. The helmet may have its characteristic visor for complete field of vision during space operations. It vaguely resembles the Security helmet, as they both share a very large visor. Because of this, it has been dubbed the "Fish Bowl" and the "Sniper Magnet" by some gamers due to the prominent, brightly colored, spherical shape of its visor.

Shoulder pauldron
Unlock: Complete The Ark level on Normal, Heroic, or Legendary difficulty.

The shoulder pauldrons are larger than the standard MJOLNIR plates and feature a long attachment to their center, another similarity to the SPI armor, which could be radios. The pauldrons also cover more surface area than other shoulder pieces.

Chest
Unlock: Complete Tsavo Highway on Normal, Heroic, or Legendary difficulty.

The chest plate is a seemingly standard MJOLNIR chest plate set with a small and minor attachment. The attachment consists of a small metal plate connected to a piece of black alloy that has several unknown equipment pieces set into it. It has been speculated that the compartment on the chest plate holds a cable that could be attached to docking ports so that a SPARTAN-II does not drift into space.

Trivia

 * The EVA helmet bears a resemblance to the Apollo Program's A7L PGA pressure helmet, which was called a "fish bowl" by the astronauts and support staff.
 * Through the Career section of Halo Waypoint, a player that has achieved Milestone 50 (3900 achievement points on all Halo titles) will receive an EVA helmet for their Xbox LIVE avatar.
 * The EVA helmet bears a resemblance to the helmet of Guy-Manuel de Homem-Christo, founding member of the French house music duo Daft Punk.
