Experience Points (XP) are a numerical quantity exclusive to multiplayer that dictates a player's level and progress in that level. One's progress through an individual level is shown on the bottom of the screen by a yellow meter, though this feature is not included in several Call of Duty games. When a player gains experience points, the meter moves further to right and resets when having achieved the next level.
Ranking through Experience Points is available in Call of Duty 4: Modern Warfare, Call of Duty: World at War, Call of Duty: Modern Warfare 2, Call of Duty: Modern Warfare: Reflex Edition, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty: Ghosts, Extinction, Call of Duty: Advanced Warfare, Call of Duty: Black Ops III, Call of Duty: Infinite Warfare, Call of Duty: Modern Warfare Remastered, Call of Duty: WWII, Call of Duty: Black Ops 4, Call of Duty: Modern Warfare (2019), Call of Duty: Warzone, Call of Duty: Black Ops Cold War and Call of Duty: Vanguard.
While experience points are also available in Call of Duty: United Offensive, there is no experience meter and the ranks reset when one ends or exits a match.
Gaining Experience Points
Call of Duty: United Offensive
United Offensive was the first game in the series to feature a pseudo-experience point system. Upon the start of each game, a player spawns as a Private with a limited amount of ammo and a single grenade. Points are accumulated from kills, flag captures, bunker destruction, and the like, with every ten points resulting in a promotion to a higher rank. Ranks and points do not carry on from game to game; they are reset for every game.
Call of Duty 4: Modern Warfare
- Killing the enemy. The player gains 10 points per kill in Team Deathmatch (all forms) and Sabotage. 5 points are earned for killing in Free for All, Headquarters and Domination. The player can gain 50 points per kill in Search and Destroy, as no respawns are permitted; the life is worth more. Kills in Cage Matches are worth 20 points. If one kills when using Last Stand perk, double points will be earned. In Headquarters or Domination, a player can score an extra 5 experience points for killing an enemy who is within an objective capture range (i.e. within a Domination flag).
- XP Stacking. The XP indicator will stack when earned in rapid succession. For example, if a player kills three people rapidly in Team Deathmatch (although this works in all modes), the player earns 10XP for every kill, and the XP that appears in the middle of the screen will continue counting past 10. Some players think that "XP stacking" means that the second kill would be worth 20 XP, and the third kill would be worth 30 XP, etc., but this is not the case.
- Assisting in the death of an enemy. If the player injures an enemy but does not kill that enemy and that player dies before their health is fully regenerated the player is awarded an assist, 2 experience points for matches which grant 10 XP a kill, 1 for kills which grant 5 XP a kill, and 25 points in Search and Destroy. Assists are impossible to achieve in Free-for-all mode.
- Completing challenges. Challenges are a new method to gain experience points. Challenges have some requirements to be fulfilled before the reward is available. For example, for Marksman challenges, one needs to kill the enemy using the pertinent gun. In Expert challenges, one would need to kill the enemy via headshots with the gun. There are also challenges that requires player to do other, more varied tasks. For example, the "think fast" challenge requires a player to kill an enemy by directly hitting the enemy with a Fragmentation Grenade. The challenges involving guns gives either attachments or camouflages as an addition to experience points. Other challenges give only experience points.
- Miscellaneous: The game gives some bonus points for the player's performance when the match ends as a "Match Bonus". The match bonus is based only on one's rank, the duration of the match and the gamemode. It does not, contrary to popular belief, include the amount of kills or deaths. In fact, a player on the top of scoreboard can still get less match bonus than a person at the bottom.
Call of Duty: World at War
The player can gain experience points in the same manner as in Call of Duty 4: Modern Warfare, but also by:
- Cooperative (Co-op) gameplay. This is a new mode where one can play the missions in normal gameplay but with 2-4 players. One can do exclusive challenges when playing in Co-op. Remember that in Co-op only the XP gained from Co-op challenges count for one's level, the XP earned in the Co-op missions for kills or objectives do not count. Playing Nazi Zombies, or playing in split screen cooperative mode, does not give any experience points
- Completing vehicle challenges
- Killing a dog. This gives 3 points in all game modes except Free for All (2 points) and Search and Destroy (not confirmed)
- Reviving a teammate who is using Second Chance. This gives the player 2 points.
- Gaining an assist. This is more complicated than Call of Duty 4: Modern Warfare as the amount of experience points gained is proportionate to the amount of damage inflicted towards the enemy. This is given in multiples of 5ths of the amount of XP given for a kill. The only exception is Search and Destroy, where all assists are worth 25 XP.
For example in Team Deathmatch:
- 10 points for a kill.
- 2 assist points for at 1-39% of damage given.
- 4 assist points for at 40-59% of damage given.
- 6 assist points for at 60-79% of damage given.
- 8 assist points for at 80-99% of damage given, includes putting an enemy in Second Chance with a teammate "stealing" the kill.
Call of Duty: Modern Warfare 2
The experience system in Call of Duty: Modern Warfare 2 contains many new additions. Instead of just receiving XP for kills and challenges, the player receives "medals" with each kill that will reward additional XP:
