One of the leading video game publishers worldwide, Activision Publishing, and Microsoft, announced today that all Call of Duty game add-ons and downloadable content packages will be first released on the Xbox LIVE Online Entertainment Network exclusively, courtesy of the multi-year agreement between the two companies.

The special interest media group, Future, confirmed that the June releases of its Official Xbox and PlayStation Magazines in the United Kingdom will reveal the first in-depth previews of the upcoming title Call of Duty: Black Ops.

Future’s Official PlayStation Magazine and Official Xbox Magazine will deliver the first hard facts about the game directly from the studio of the developers in California. Teased from the Call of Duty: Black Ops trailer, gamers will no longer have to look at the rumors on the internet. The Call of Duty: Black Ops first-person shooter is expected to release on the 9th of November, 2010 according to the announcement trailer.

The name of the new upcoming Call of Duty game by Treyarch is “Call of Duty: Black Ops”. Call of Duty: Black Ops is expected to release on 9th of November 2010, as stated on the official site callofduty.com/blackops.
