Plants vs Zombies is an app created by veteran casual game maker PopCap. The game is essentially a tower defense game which pits your own homegrown plants against an onslaught of evil zombies. As you progress through the game, you will collect new types of plants to counter the growing variety of mind-munching monsters attacking your door.

You will utilize the long range peashooters, the explosive cherry bombs, the sunshine-producing sunflowers, and many more. In order to produce more plants, you will have to collect sunshine that falls from the sky or plant sunflowers to produce extra resources. The game begins with only one row of attacking zombies but as you grow in experience, the game will expand to 5 rows of mayhem. In later levels, the placement of various plants becomes key. New types of zombies will attack quickly or become extremely difficult to take down.

Overall, the game is a great mixture of cartoon fun and solid strategy. It offers enough difficulty to keep you guessing and the adrenaline pumping but it also brings a relaxing experience for anyone to enjoy. The graphics are great and the sounds help to complete the experience. For a medium price, this app is well-placed on the iPhone along with many of the other PopCap games.
