2. Call of Duty: Zombies
If you want to kill Nazi zombies then look no further because Call of Duty WAW Zombies is waiting for you at the App Store. All you have to do in this game is to just eliminate those sucking Nazi invaders.
Unlike other Call of Duty games, this games offers you short and sweet gameplays and a number of zombies to kill with so little time. A level lasts for about 2-3 minutes in most of the cases but the same 180 seconds will be very difficult to survive.
However, a wide range of weapons available at the armory make your task easier by kicking the ass of those freaking zombies.
