Halo 4 Armor Unlocks
Halo 4 offers a host of customizability options for players to create their own distinct Spartan in the game’s multiplayer modes, otherwise known as Infinity Multiplayer. As you earn experience points in multiplayer and gain Spartan Ranks (SR), you’ll be able to unlock new pieces of armor for which to bedeck your character.
Gaining ranks isn’t the only way to earn new armor however, as you’ll also be given the opportunity to unlock new pieces of armor by getting Commendations. These range from completing the game’s single-player campaign on Legendary mode, to becoming a “Master” at the various multiplayer modes.
Completing Specializations will also allow you to unlock new pieces of armor.
Finally, pre-ordering the game from various outlets like GameStop and Bestbuy, or picking up the Limited Edition of the game will also earn you certain types of armors.
If you’re wondering what you need to do to unlock the various armors in Halo 4, we’ve compiled a guide based on information provided by 343 Industries via its updates on the Halo Waypoint, this reddit thread and the game itself. The details in the list (sans images) were compiled by Cliffhangerzero on reddit with the aid of the site's Halo community.
