Leveling up still is a major part in the game; weapons are unlocked through progressing levels, but still need to be bought. Players unlock all Perks, Grenades, Equipment at level four, along with Create-A-Class.
The highest level attainable is 50, and when level 50 is completed, Prestige Mode is offered. There are 15 levels of Prestige, instead of the more regular 10, seen from Call of Duty 4: Modern Warfare onwards.
