The helmet has one small visor that resembles a pair of rap-star style sunglasses, rather than the normal and typical MJOLNIR Mark VI visor. The mouth-guard appears longer and thicker with an added "hole" in the center of the mouthpiece, and it also appears to be added-on plating rather than an actual mouth-guard. The top of the helmet, which has been mistaken for the "stealth" helmet, is much more rounded as well. The mouth guard rounds, shapes, and cups into a circular black piece in front of the mouth that forms the aforementioned "hole," and notice the fact that there are no specific shoulders. The Rogue Helmet is a variant of the standard Mark VI MJOLNIR powered battle armor. It is an armor permutation in Halo 3 multiplayer. This armor permutation, like all others, has no effect on gameplay and is purely aesthetic.

* Head: Unlock the Spartan Officer achievement, obtainable only through online multiplayer.

Note: If you have unlocked the Spartan Officer badge, but do not have the rogue helmet, you can obtain it by achieving a rank of Lieutenant in any of the new playlist-specific ranking systems.
