In order to properly defend yourself against these undead warriors, the player has access to a wide variety of dangerous and lethal plants that all have their own unique abilities and must be strategically placed along the various paths to ensure your defense and survival. The game starts off slow, allowing users to acclimate themselves to the game style as players are taught and reminded that they must be careful about defending and watching all 6 lanes at all possible times. Zombies is unique in that it embraces a 6 horizontal lane design where zombies can come towards you down any given lane at any given time, oftentimes across multiple lanes at the same time! Prior to this game, the genre tended to stick towards a single-lane setup where enemies approached the player down a singular, predictable pathway. Zombies originally released, it was known primarily for innovating the tower defense strategy genre. What is the main point of defense against this scary legion of undead zombies? Your homeowner's carefully placed and curated home garden, of course! When Plants vs. Zombies is a tower defense strategy developed by the legendary PopCap Games that puts the player in the place of a homeowner tasked with defending himself against a coming zombie apocalypse.
