Call of Duty: Black Ops (also known as simply Black Ops) is the seventh main installment of the Call of Duty series and is currently being developed by Treyarch. The confirmation of the game's development was leaked by David Kim, a senior animator at Treyarch, in May 2009. Black Ops is said to be set in various locations, including Vietnam and Cuba,  and judging from weaponry and dates given in the trailer, it is set between 1960 and 2010. It is planned to be released on November 9, 2010. Treyarch has stated that Black Ops will be much grittier than Modern Warfare 2 and that the differences between World at War and Black Ops will be as significant as the differences between Call of Duty 2 and Call of Duty 4: Modern Warfare. The trailer released on May 18, 2010 indicated that the game will be significantly more story-oriented and will focus on military cover-ups during the Cold War. Treyarch has also said that Black Ops will feature considerably more stealth than any previous entries in the Call of Duty series.
Vietnam, Cuba, the Arctic, Laos and Russia have been confirmed as locations in the game.
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.
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
Create-A-Class 2.0 will allow players to customize their appearance in addition to their loadout. 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.
