rmor Permutations are a feature in Halo 3, Halo 3: ODST, and Halo: Reach that enable players to customize their multiplayer character's armor to their liking. In Halo 3, this feature allows players to change the helmet, shoulder, chest pieces worn by their multiplayer character. In Halo 3: ODST, players can choose between the preset armor of their squad members, and can toggle whether or not their character wears a helmet, though this will not affect health. In Halo: Reach, players can purchase different armor from The Armory, which also includes wrist armor, knee guards, utilities, visor colors, and armor effects. Players also have the option of choosing between being a Spartan or Elite in Halo 2 and Halo 3, and can set a preference for either in Halo Reach.
