Call of Duty: World at War: Zombies supports up to four players over Wi-Fi, and two players over a local Bluetooth connection. You can use the iPhone's tilt sensors, or the always enjoyable virtual analog thumbsticks, to control the game. With Apple remaining hands-off in the space, the game supports "Achievements" and a "Leaderboard," but they're presumably isolated from other games. The description also promises that the game will "fully support future Downloadable Content, ensuring that the classic survival experience will live on with new maps." Thanks, in-game purchasing!
What's less clear is who is behind the development of Call of Duty: World at War: Zombies. The iTunes Store lists the game under "Vivendi Games Mobile," the presumably outdated name of Vivendi Games' mobile gaming arm, taken over during the 2007 merger. We've put a line into Activision. [Update: The press release just went out over the wires, and it states that Zombies was "developed by Ideaworks Game Studio" who have brought other high-profile cell phone games to market, including Metal Gear Solid Mobile, Project Gotham Racing, and Dirge of Cerberus Lost Episode Final Fantasy VII.]
