Plants vs. Zombies is a strategic tower defense game developed by PopCap Games for the Android, iOS, Mac OS, Microsoft Windows, Nintendo DS, DSiWare, PlayStation 3, PlayStation Vita, Xbox 360, and Windows Phone. The game involves a homeowner using many varieties of plants to repel an army of zombies from "eating their brains".
Players place different types of plants and fungi, each with their own unique offensive or defensive capabilities, around a house in order to stop a horde of zombies from eating the brains of the residents. The playing field is divided into a number of horizontal lanes and zombies commonly move towards the house on one path. Most plants can only attack or defend against zombies in the lane they are planted in, but in later levels players can purchase upgrades to adapt their lawn mower to new environments like pools or rooftops.
