During their Spartan careers, players are offered Specializations through a variety of channels, allowing them to enlist in specific rank paths that come with armor sets, armor mods, emblems, and a variety of other components.
When a player reaches rank 50, they are allowed to select a Specialization. The Specialization consists of an additional 10 ranks and over the course of these ranks, the player will unlock various bonuses. Each Specialization completed allowed the player to increase their rank an additional 10 times so that after completing one Specialization, the player will be at rank 60, after completing two specializations, the player will be rank 70, etc,. The current maximum rank for a player with access to all of the Specializations is rank 130. Doing this requires either the Limited Edition version of the game or playing within the first two months of release.
These paths are composed of ten rank levels each, which the player, once opting for the Specialization, must complete in order to improve their rank and before being allowed to enlist in a separate Specialization. Each Specialization unlocks the following items as you progress across its 10 levels:
• Armor Mod
• Armor Set – Helmet, Chest, Left Shoulder, Right Shoulder
• Armor Set Skin – Texture skin for Helmet, Chest, Left Shoulder, Right Shoulder
• Weapon Skin – Texture skin of one of the loadout weapons
• 4 Foreground Emblems• 1 Background Emblem
• 1 Visor Color
