You'll be planting all sorts of crazy plants, from peashooters to sunflowers, to take down the undead hordes. As you progress through levels, you'll unlock new plants and power-ups to add to your arsenal. It's amazing how much strategy goes into figuring out which plants to use and when.
The core loop is all about collecting sun to plant more seeds, while also defending your lawn from the zombie invasion. You'll be tapping away, planting plants and collecting sun, all while trying to outsmart those zombies. It's such a satisfying feeling when you finally take down a tough level!
