An all-new action-strategy game from PopCap, makers of Bejeweled and Peggle! Zombies are invading your home, and the only defense is your arsenal of plants! Armed with an alien nursery-worth of zombie-zapping plants like peashooters and cherry bombs, you'll need to think fast and plant faster to stop dozens of types of zombies dead in their tracks.

Play five game modes: Adventure, Mini-Games, Puzzle, Survival, plus the stress-free Zen Garden Conquer all 50 levels of Adventure mode — through day, night, and fog, in a swimming pool and on the rooftop Battle 26 types of zombies including pole-vaulters, snorkelers and “Zomboni” drivers Earn 49 powerful perennials and collect coins to buy a pet snail, power-ups and more!
