Halo 4’s unlock system is tied into Spartan Ranks, the new leveling system that has been implemented in Halo 4. Players rank up by earning experience.This can be done by participating in the game’s competitive multiplayer, completing challenges, earning commendations and taking part in the game’s Spartan Ops mode.

The maximum Spartan Rank available is level 50 and with each additional rank you earn, you will unlock additional weapons, armor abilities, support upgrades, tactical packages and other various character improvements including additional custom load-outs, and armor sets. Each level gained will also earn a Spartan Point which can be used to purchase unlocked firepower.
