A range of new features have found their way to the official Halo site today, expanding on the experience when away from the console. In today’s update, Halo 5: Guardians developer, 343 Industries has introduced new methods of personalization, when using the desktop version of the Halo site.
With these changes, it is now possible to customize your Halo 5: Guardians multiplayer Spartan by equipping armor sets and helmets that have been unlocked so far. While the game has not yet launched, promotions and other merchandise have included redeemable codes for REQ packs, which include weapons and power-ups that can be used in the Halo 5 multiplayer experience.
As shown in the above screenshots, the tool allows players to edit the aesthetics of their Spartan, before purchasing the game. From here, it is possible to experiment with all visors and armor sets, even if the armor set is currently locked. These armor permutations are then displayed on a 3D model. Assumedly at launch, these character setups will transfer to the multiplayer on Xbox One.
The Halo 5 online customization tool can be found when logged into your Xbox Live account, on the Halo official site.
