Armor permutations

Armor permutations are features in Halo 3, Halo 3: ODST, Halo: Reach, and Halo 4 that allow players to customize their multiplayer character's armor to their liking. In Halo 3 and Halo: Reach, this feature allows players to change the armor pieces worn by their multiplayer character. Halo 3: ODST allows the player to choose between squad members, and thus take on their own specific ODST armor configuration. Players also have the option of choosing between being a Spartan or Elite in Halo 2 and Halo 3, whereas Halo: Reach allows full body customization of Elite armor along with Spartan Armor. Halo 4 does not allow Elite customization or even playability, unlike most of the past games, but it does continue each game's allowance of gender choice.
