Halo CE Adding Customization Options

A recent MCC Development Update on the Halo Website discusses the addition of visor, weapon, and vehicle skins to Halo CE multiplayer in Halo: The Master Chief Collection (thanks GameSpot via Neutronbeam). For traditionalists, there will also be an option to toggle off the new skins so they will not be shown on your end. Here's word on customization options:
Visors:
When other players see you in the match, they will be able to see your new custom visor color. This visor color change will not affect any first person HUDs to keep the look of the original game intact. When a custom visor is selected, it will always show to other players if the option to enable new skins is turned on.

Weapon Skins:
Players will now be able to customize the look of both UNSC and Covenant weapons. Even the default skins will be enhanced in Halo: CE. The way these skins will work is that when a player picks up a weapon that has a custom weapon skin, the weapon will change its looks to match that skin and other players will see this as well. If this weapon is dropped, it will retain the look of that skin until a player with a different skin picks it up, in which case it changes to the custom skin that player has set.

Vehicle Skins:
Players will now be able to customize the look of both UNSC and Covenant vehicles. Even the default skins will be enhanced in Halo: CE. The way these skins will work is that when a player enters the driver seat of the vehicle that has a custom skin, the vehicle will change its looks to match that skin and other players will see this as well. If this vehicle is exited, it will retain the look of that skin until a player with a different skin enters the driver’s seat, in which case it changes to the custom skin that player has set.
