Plants Vs. Zombies: City Defense

This next installment is like Plants Vs. Zombies Adventures, but with a twist.

Information
Most of the 'tiles' are represented by the icon on it. A zombie head means only regular zombies, a buckethead zombie head means regular, cone, and bucketheads. The brain icon means it's a special tile, and you will gain something new. For example, an item is 'Enchanted Pea Ammo'. (20% chance for Peashooter's peas to pierce).
