Call of Duty: Black Ops is a first-person shooter, developed by Treyarch and published by Activision.

Unlocking the mode is easy: simply find the four missing coins in the game menus. Luckily for you, not only the weapons and benefits that you love about Call of Duty are at your fingertips, but you can join up to 4 players via Wi-Fi to play in the multiplayer. Keep in mind that CoD points are only applicable in a single player. With six levels of in-app purchase options to choose from, Zombie fans can take their experience to a whole new level by unlocking additional areas and securing better weapons in much less time. Players can also choose to improve their experience and get out of a jam with the CoD point system in the game. Play alone or join a team of up to 4 players via Wi-Fi while defeating hordes of zombies with a variety of weapons and benefits only available in the Call of Duty zombie experience.
