So, from the moment you start playing, you're dropped into this zombie-infested world where you have to defend your home using all sorts of plants. It sounds weird, but trust me, it's so much fun! You'll be planting peashooters, sunflowers, and all these other crazy plants to take down the zombie hordes.
As you play, you'll notice that each level gets progressively harder, with new types of zombies and obstacles popping up all the time. But that's what makes it so addictive - you'll want to keep playing to see what's coming next and to try out new plant combinations to take down the zombies.
