So, from moment to moment, you're planting all sorts of plants to take down waves of zombies. It's pretty straightforward, but it gets crazy fast! You've got your basic peashooters, but then you've also got bonk choys and laser beans to spice things up.
As you progress through levels, you unlock new plants and upgrades, which is super satisfying. I mean, who doesn't love a good power-up to help them take down those pesky zombies? And the leveling system is pretty cool too - you get to choose which plants to upgrade, so you can tailor your strategy to your playstyle.
