Production overview



Technical specifications


Aggressive in-built artificial intelligence[1]


ACHILLES-class Mjolnir is a variant of the Mjolnir [GEN2] armor.[1]


Design details[edit]

The Achilles suit's neural interface is equipped with a savage AI that gnaws at the mind of its user, easily leading to excessive violence in combat.[1]


Only select Spartans who have mastered themselves are allowed to requisition the Achilles set, as unskilled wearers will quickly lose themselves to uncontrolled rage at the hands of the suit's embedded AI.[1]

In-game information[edit]

Halo 5: Guardians[edit]

Achilles was added into Halo 5: Guardians in the Infinity's Armory update. It is unique among the Halo 5 armor sets in that it is one of the few that can only be unlocked via specific in-game achievements, as opposed to the requisition system.[2]

Production notes[edit]

Help.png This section needs expansion. You can help Halopedia by expanding it.

Achilles was known internally as "A102_S000 Waypoint Companies Armor" during development.[3] The armor was initially accidentally unveiled with the Cartographer's Gift update, when some glitched REQ cards were available to view with the Achilles name - though only placeholder imagery.
