For those unfamiliar with the genre, tower defense games are part arcade game, part real-time strategy, where your goal is to build defensive and offensive structures on the fly in order to stop waves of enemies from marching from one end of the screen to the other. In this case, you must protect your house from the zombies advancing across your lawn.

Luckily, you're quite the green thumb, and can grow plants that slow the zombies down. But you'll have to be crafty, because different kinds of zombies have different strengths and attributes, like the zombie who was a buff football player in its former life, or the one that wears an orange construction cone on its head for protection.
