Plants vs Zombies: Game of the Year Edition...Get ready to soil your plants in an all-new action-strategy game from PopCap! A mob of fun-loving zombies is about to invade your home, and your only defense is an arsenal of 49 zombie-zapping plants. Use peashooters, wall-nuts, cherry bombs and more to mulchify 26 types of zombies before they can reach your front door.
Each zombie has its own special skills, so you'll need to think fast and plant faster to combat them all. But be careful how you use your limited supply of greens and seeds... as you battle the fun-dead, obstacles like a setting sun, creeping fog and a swimming pool add to the challenge. And with five game modes to dig into, the fun never dies!
