Armor customization

Introduction
Originally discovered in the Halo 3 Beta code by modders, Halo 3's new multiplayer armor permutations provide high levels of player customization and were confirmed by GamePro's June issue.

The armor permutations are completely cosmetic; they cause no change in gameplay.

Higher resolution screenshots of the armor permutations in action can be found at the Halo 3 Project's screenshots section at Bungie.net, as of July 2, 2007.

Bungie has stated that there are "thousands" of possible combos, but they refuse to state exactly how many variations will be in the final product, including downloadable content.

In the Bungie Podcast, it was confirmed that 2 SPARTAN and 2 Elite variant armors are given at the start--For SPARTANs, this includes the MJOLNIR Mk. VI armor, and the CQB(Close Quarters Battle) permutation, and for the Elites, the Combat and Assault permutations are included.

Bungie hinted to more types of armor in the June 8, 2007 Weekly Update, along with the June 22, 2007 Weekly Update: "Players were using different permutations than we’ve shown."

There were 5 permutations for Spartans discovered by modders in the Beta code; Bungie confirmed two before the release of Halo 3: EVA(Extra-Vehicular Activity) and CQB(Close Quarters Battle).
