Finally combining my love of gardening and my need to slaughter the undead, Plants vs. Zombies is a unique tower defense game from PopCap Games.
In Plants vs. Zombies, you're a home owner with a zombie problem. The undead want to invade your yard and get to your delicious brains. Your best defense is to plant peapods, mushrooms, squash, and other deadly legumes (deadly to the undead, that is) to fight back the zombie hordes.
The beautiful cartoon artwork is on the right side of zany and sets a light-hearted tone from the get-go. The zombies are silly, distinctive enemies that vary in character, from your standard groaning zombie to zombie football players, zamboni-riding zombies, zombie dolphin teams, and zombie balloon riders. Each has a distinct battle skill that you'll have to confront.
