A whole ago, Activision and Treyarch released an iOS game called Call of Duty: World at War zombies which did so well they announced that tomorrow (December 1st) you can get your hands on their next installment with Call of Duty: Black Ops Zombies.
The game features which you may have guess — Zombies mode that is going to replicate Black Ops console gameplay. You will be able to play all the default maps that came with original game as well as 50 levels of the hidden gem of Dead-Ops Arcade. With this new installment gamers can also play together with up to four people using the new voice chat feature; however, I am unsure whether or not iPad players will be able to play with iPhone players as that was an annoying issue for me in the past.
Call of Duty: Black Ops Zombies is optimized for 3rd-generation devices and you will be able to download it for only $6.99. Should also note, if you want a better gameplay experience I HIGHLY recommend joystick add-ons for your iPad.
