It's free! and it's compatible with iPhone, iPod touch and iPad. A game that you can play anytime without needing internet connection.
 
I never knew that planting your own army of zombies could be so much fun. There are a lot of different kind of zombies you can choose from depending on the level you're at. Besides that, you also can plant other kind of crops to earn some money. The best thing about this game if that when you have enough zombies, you can invade a farm/city/area (tap away....)
When you win the invasion, you receive a new zombie skill award and some loot. By having some brains, you can expand your farm by buying more grounds, accessories, mutations, and great equipment.
Beware! It's quite addictive. You have to make sure that you keep plowing, planting, and making them happy (especially when they're hungry).
