Introducing Plants vs. Zombies, the side-splittingly funny, renowned, award-winning Tower Defence game. The aim is to defend your house against an invasion of crazy zombies by growing plants in your garden. Think methodically, don’t be a shrinking violet, and plant sunflowers to harvest energy. The zombies are there to destroy you, so nip this attack in the bud and don’t end up pushing up the daisies!
