Armor customization (Halo 3: ODST)

Armor Permutations are a feature in Halo 3, Halo 3: ODST, and Halo: Reach that lets players customize their multiplayer character's armor to their liking.

Overview
Halo 3: ODST features armor customization, though it is not as complex as Halo 3 ' s. One can play as each member of the squad having their own unique aesthetic Bungie-created armor. Players can choose primary and secondary armor colors, but the armor's main color remains the same (dark gray). Players can also choose whether or not to wear a helmet, unless they are playing as the Rookie or Sergeant Johnson, who cannot remove his helmet and cannot put one on, respectively. Choosing not to wear a helmet does not affect gameplay. Without a helmet, the player still has the same health and stamina, and they can still use VISR mode. Each character has their own unique lines of dialogue which play during gameplay.
