Aside from the compelling campaign, Call of Duty: Black Ops has a variety of modes, including Treyarch’s unique Zombies Mode, putting players in a setting overrun by the hungry dead.

Call of Duty: Black Ops is considered the seventh game in the Call of Duty franchise. Infinity Ward developed Call of Duty from the beginning with the first two that took place during the World War II. Treyarch’s developers stood in for Call of Duty 3. A sequel was a must as Infinity Ward took the series into a different direction with Call of Duty 4: Modern Warfare. The later sequels began to ignore the sequel numbers in their title. http://www.treyarch.com/

Infinity Ward has been rumored to depart from the Call of Duty franchise and develop their own series based on their complete success with the Modern Warfare spin-offs, leaving Treyarch to helm future sequels for Activision.http://gameinformer.com/b/news/archive/2010/04/23/four-more-join-infinity-ward-exodus-seven-respawn.aspx
