Originally released for consoles and PC as a bonus mode in “Call of Duty: Black Ops,” due to its popularity Activision released “Call of Duty: Zombies” as a standalone iPhone game. Much like the original game, “COD: Zombies” relies heavily on multiplayer, increasing the odds of surviving longer when there are more players in the game. The game allows you to connect with other players online, such as by hosting a game and letting others join it. You must have an active in-game profile and a 3G, 4G or Wi-Fi Internet connection to play online. Tips Warnings Writer Bio
