Call of Duty: Black Ops is an upcoming 2010 first-person shooter video game developed by Treyarch and published by Activision for release on November 9, 2010. Officially announced on April 30, 2010, it was unveiled alongside the game's debut trailer on GameTrailers TV Episode 310. The game is the seventh installment of the Call of Duty series and the fourth game in the series to be developed by Treyarch after Call of Duty 2: Big Red One, Call of Duty 3 and Call of Duty: World at War.

Players take the role of a Black Ops operative who will be involved in missions behind enemy lines. Missions will take place in a variety of locations, including Cuba, the Arctic, and Vietnam.

The game was first officially unveiled when the official site for the game went live prior to the release on the game's reveal trailer on April 30, 2010. Along with the site, a blog was also uploaded which contained an official announcement of the game by Treyarch which was dated April 29, 2010 a day prior to the game's unveiling. In May 2009, publisher Activision was rumored to be looking for licensing regarding Vietnam War-era music which led to speculation that Call of Duty 7 would be set in Vietnam. In February 2010, a casting call for Call of Duty 7 led to speculation that the game would be taking place during the Cold War era with some battles taking place in South Vietnam. In late April 2010, Activision possibly released a teaser site for the game whose address had to be revealed through a word cipher from a brown envelope sent to various gaming news publication via mail[citation needed]. On May 1st, Treyarch released a teaser trailer.
