Multiplayer
- Vehicles will return, but they will be very different than those in Call of Duty: World at War.
- Black Ops will feature a dedicated co-op campaign, supporting up to four players, which uses different levels than the singleplayer campaign. When asked about zombies in an interview, they stated that they could not talk about the co-op campaign, hinting that it will be a zombie 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 multiplayer maps instead of the typical vice-versa. This change is because some multiplayer maps had been made before the campaign was finalized.
- Create-A-Class 2.0 will allow players to customize their appearance in addition to their loadout.
- 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 perks, Commando and One Man Army, are not going to return.
- The PC version of Call of Duty: Black Ops will feature dedicated servers.
- Shotguns and Machine Pistols as secondary weapons are not expected to return, as Treyarch stated in an interview that they give the player "too much firepower".
