Barebones Pro is a playlist in Call of Duty: Modern Warfare 2 and Call of Duty: Black Ops. It was added to the Xbox 360 platform on June 21, 2010, and was added to PlayStation Network and the PC with the Resurgence Map Pack, but not as part of it, on the week of July 6. It has two game modes in it, Team Deathmatch and Free-For-All, allowing 4-8 players. In this playlist, all Killstreak rewards are disabled. Other than that, the two modes remain the same except for the smaller maximum of 8 players per game. Xbox LIVE Party Chat is also allowed. Barebones Pro has an objective-based game counterpart, Objective Barebones Pro. As of March 23, 2012, Barebones was added for Modern Warfare 3. It is the same as its Black Ops and Modern Warfare 2 counterparts.
In Black Ops, players' Killstreaks, Perks, Camouflage, and Attachments are not allowed. In the Wii version, players' Contracts are not allowed. Barebones is now an official playlist in Call of Duty: Black Ops.
- Despite having no killstreaks, Deathstreaks are still active.
- Talk of this type of playlist originated back in 2008 following the Variety Map Pack release on Call of Duty 4, along with Hardcore Ricochet and Second-Chance Search and Destroy. Hardcore Ricochet has also been implemented in Modern Warfare 2. However, the Barebones that was talked about then was also planned to disable perks and attachments along with killstreaks. 
- Boosting is very common in this game mode because there are no killstreak rewards to get killed by. Often players will join with 4 players then invite 4 other players into the game, thus making an even lobby. They will then do what is sometimes known as "mass boosting". 4 players can also glitch into a private lobby which still gives public match XP and challenges.
- In addition to above, a player can have 3 other players in a party join a Barebones match, then invite 4 other players for an even lobby. If the player wants to play Free For All (FFA), then have everyone skip when the upcoming map is set for Team Death Match (TDM). Skipping a TDM will usually result in the next map being Free-For-All.
- It is easier than most other game modes to complete the challenge "The Loner" (get a 10 kill streak with no killstreak rewards enabled), due to the lack of enemy killstreaks.
- It is possible to search for a Barebones Pro lobby with six total players in the party. However, a game will not start unless it is Free-For-All (Barebones Team Deathmatch is 4v4).
- This game mode is also used by large parties of friends who want to play together. Unlike regular FFA, it allows parties to play.
- Barebones Pro on the Wii is just known as Barebones.
- Some game lobbies may have a glitch occur, where it gives a false indication of a maximum 264 players per lobby.
