EOD-class Mjolnir
From Halopedia, the Halo wiki
Introduction
One of the five Spartan armor permutations to be featured in Halo 3. Bungie hasn't released the name of the armor. It is speculated to be the ninja armor.
Trivia
- It looks like the armor of the GEARS from Gears of War, or possibly a Helghast from Killzone.
- It seems likely that the armor may be a "sniper variant". Instead of a faceplate, there are just 2 slots for the eyes; much less visible and therefore very valuable to a sniper.
- In a screenshot at IGN.com of the recently announced multiplayer map Isolation in the very corner right a spartan is seen what appears to be this Armor variant.
