Call of Duty: Black Ops (or simply Black Ops) is a first-person shooter video game developed by Treyarch, published by Activision and released worldwide on November 9, 2010 for Microsoft Windows, Xbox 360, PlayStation 3, Wii consoles, with a separate version for Nintendo DS developed by n-Space. Announced on April 30, 2010, the game is the seventh installment of the Call of Duty series, and the first to be set in the Cold War and the fifth to be set in World War II. It is the third in the series to be developed by Treyarch, and is a sequel to the developer's Call of Duty: World at War.
The first four maps (Nacht der Untoten, Verruckt, Shi No Numa, and Der Riese) are remakes of the environments from Call of Duty: World at War, the game that first introduced zombies. The fifth map--Moon--is entirely new and takes place in outer space, on the moon.
The four upgraded World at War maps won't be new to all gamers. These maps were included with the Hardened and Prestige iterations of Call of Duty: Black Ops. Owners of these top-tier editions can download the Rezurrection pack for free on August 23 to get the Moon map, soundtrack, and theme.
In a postearnings conference call, Activision Publishing CEO Eric Hirshberg said the company had already sold more than 14 million add-on packs for Black Ops. He also compared the game to microtransaction-driven titles on Facebook, saying Call of Duty sees more daily unique players and has higher average revenues per player than any title on the social network.
The publisher also elaborated further on the series. According to the publisher, Black Ops was the best-selling title in the US and Europe for the first six months of 2011, with players logging a cumulative 2.2 billion hours of online action in the game.
The series is also trending upward, as Activision said the total number of unique online gamers in Black Ops' first eight months has surpassed that of its predecessor, Call of Duty: Modern Warfare 2, by 30 percent. The next installment in the series could be even more successful, as Activision said that preorders for this November's Call of Duty: Modern Warfare 3 are significantly higher now than they were for Black Ops at the comparable point in that game's development. Finally, the publisher confirmed that it is still working on bringing a microtransaction-driven installment in the Call of Duty franchise to gamers in China.
Hirshberg also updated the lifetime-to-date sales for Black Ops and Modern Warfare 2. Black Ops has now sold 25 million copies since its November debut last year, surpassing its predecessor's lifetime total of 22 million units sold.
