BBB: App-ocalypse is a game about zombies-style Tower Defense. But distinguishes this game from many similar excellent graphics and great features. The gameplay itself is the arrangement of actors on the field, following a strategy based on the capabilities of units:

• the clerk in a white shirt effective at close range
• fast food worker to distract the zombies, giving them hamburgers
• a police rifle
• the guy with the stun gun mowing down zombies like a storm
• etc

In addition, you will be able to level each character up to 5 times and everyone is your new hero. So, the guy with the bat will be a lumberjack with an ax, then ninja, etc. and reaching 5th of transformation - it is super-hero with a chainsaw, which is nothing!
WELL, plenty of other features type of shop with bonuses, changing pictures, choosing difficulty, etc.
