Multiplayer
* Vehicles will return, but they will be very different than those in Call of Duty: World at War.
* There will be a dedicated co-op campaign, supporting up to four players, which will use different levels to singleplayer campaign.
* Treyarch is considering releasing a beta-build test, and has hinted that it is likely.
* Matchmaking is being changed so that it is easier for friends to play together.
* Some campaign levels will be based off of multiplayer maps instead of the typical vice-versa. This is because some multiplayer maps were made before the campaign was finalized.
* Create-a-Class 2.0 will allow players to customize their appearance in addition to their loadout.
* The customized killstreaks will return, but the game-ending Tactical Nuke will not. Kills earned from killstreak rewards will not count towards increasing a player's killstreak.
* The Call of Duty: Modern Warfare 2 perk 'Commando' is not expected to return.
* The PC version of the game will feature dedicated servers.[citation needed]
