Hey, Son! I have a thing or two to teach you about the zombie apocalypse. So, here's what you gotta do. You see that lawn, right in front of ya? Well, that's where you plant your army of plants to defend our turf. Yep, plants are like our secret weapon against those goofy zombies. You got all sorts of plants, like pea shooters that spit out peas at the zombies, sunflowers that give you the sunshine energy to buy more plants.
