Call of Duty: Black Ops - Escalation is a 2011 DLC expansion requiring the base game, adding five new maps: four competitive multiplayer arenas (Hotel, Convoy, Zoo, Stockpile) set in diverse global locations, and the cooperative Zombies map "Call of the Dead," which introduces new playable characters portrayed by horror film stars battling the undead in a Siberian outpost.
This DLC primarily focuses on delivering new battlegrounds across its two main components: competitive multiplayer and the cooperative Zombies experience. The content integrates directly into the existing framework of the base game.
Four new maps provide distinct combat arenas for players, each offering unique tactical layouts and visual themes:
The cooperative survival mode receives a major addition centered around a new narrative and cast.
This dedicated Zombies map transports players to an abandoned Siberian outpost situated near the coast. A key feature of this installment is the introduction of new playable characters, portrayed by a cast of iconic horror film stars, who must battle the undead horde in this desolate, chilling location.
This content pack was initially launched for the Xbox 360 and subsequently made available for PC (Microsoft Windows) and PlayStation 3. It is also accessible on the Xbox One platform via backwards compatibility. As a DLC, it functions strictly as an extension, requiring ownership of the base game to utilize any of the five included maps.
The atmosphere shifts dramatically across the new additions, moving from the tropical decay of Havana to the stark, cold environments of Russia. The settings emphasize distinct visual themes, such as the abandoned infrastructure of the Soviet Zoo and the high-stakes secrecy surrounding the WMD stockpile in the Russian village. The Zombies map specifically leans into a cinematic horror aesthetic with its Siberian island setting.
