COD: Black Ops


 * "A lie is a lie. Just because they write it down and call it history doesn't make it the truth. We live in a world where seeing is not believing. We live in a world where everything we know is wrong."

Call of Duty: Black Ops (also known as simply Black Ops orBO) is the seventh main installment of the Call of Duty series and was developed by Treyarch.[2] The game was released on November 9, 2010[3].

The confirmation of the game's development was leaked by David Kim, a senior animator at Treyarch, in May 2009. Black Ops is set in various locations, including Vietnam and Cuba. [4] Black Ops is much grittier than Modern Warfare 2 and the differences between World at War and Black Ops are as significant as the differences between Call of Duty 2 and Call of Duty 4: Modern Warfare.[5] . Black Ops features considerably more stealth than any other entry in the Call of Duty series.
