There are 15 levels of prestige.
In the Black Ops rank system, the player must level up to unlock weapons for purchase.
Drivable vehicles will return in the form user-controlled killstreaks such as the RC-XD and Chopper Gunner.
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.

Matchmaking is being changed so that it is easier for friends to play together, and there will be a regional filter [10]
In-game currency will be used to purchase weapons and upgrades.
Split screen online for the Xbox 360 and PS3 has been implemented.

CoD Points:
CoD Points are a new major feature of Black Ops. CoD Points will become the new in-game currency and will allow players to buy weapons, attachments, and Contracts. In addition to this, players are also allowed to wager these points in certain game modes.


Contracts are a new system in addition to the classic challenge system in Black Ops. A player is able to buy a contract with CoD Points, which will then direct them to complete an object. Completion of a contract will yield a higher CoD point payout than what was originally paid for the contract itself.

Wager Matches
A new mode with a separate ranking structure than the standard online modes, will allow players to gamble with their money. However, only the top three will receive the prize. They will be placed into one of four random modes:

One in the Chamber - each player is given a pistol with one bullet and a knife. For each kill achieved the player will receive one more bullet. However, each player will only have three lives.
Sharpshooter - each player is given the same random weapon. The weapon will be used for 45 seconds before being switched out for another one. Kills will award the player with perks and score multipliers.
Sticks and Stones - each player receives only a crossbow, ballistic knife, and a Tomahawk. The catch in this gamemode is that if the player was able to hit an enemy with a Tomahawk, the enemy player will go "bankrupted".
Gun Game - players start out with a pistol. For each kill they move up a level, granting them a better gun. First person to achieve kills with all 20 weapons wins. However, someone who is knifed will move down a level.
Create a Class Edit

Create a Class in Black Ops.
It will allow players to customize their appearance in addition to their load-out. Players may see what their character looks like while choosing a class, as the player's basic appearance will be determined by their Tier 1 Perk. Players will also be able to choose a Facepaint pattern.
Some sights such as the Red Dot Sight can use custom reticules which includes choice of shape and color.
Gun camouflages will be featured in Black Ops and will be far more numerous than in previous Call of Duty games.
Players' clan tags are engraved onto their guns.
