Ranking up allows weapons and equipment to be unlocked, as with previous Call of Duty games, but they must be purchased with CoD Points to be utilized. All attachments are available to the weapon(s) purchased, but also must be purchased individually. Every perk is available from level 4, and must be purchased as well. All Killstreaks are unlocked at level 10 for purchase.
CoD Points can also be wagered in Wager Matches or used to buy Contracts. CoD points awarding is simple: excluding challenges and contracts, the player will receive 10% of their XP in CoD points. For example, if a player gets 3000 XP in one game, they will earn 300. In Wager Matches, more CoD Points are earned each game due to the high-risk gameplay of the matches. 1000 is earned when promoted on odd levels, and 2500 is earned when promoted on even levels. These bonuses allow new players to rack up enough points in the first few levels, which can in turn be spent on the first weapons or customization choices. All CoD points are lost when a player prestiges, so excess points should be spent on playercard elements or the ability to put the player's emblem/clan tag on a weapon, which are the only permanently bought things in the game.
