I’ve played many tower defense games, but I was unprepared for how both simple and complex this game turned out to be. You’re only tasked with managing five rows, but the sheer amount of different zombies that the game throws at you can be overwhelming if you aren’t familiar with your towers…erm…plants. This game turned out to be extremely popular…popular enough that Blizzard featured it in World of Warcraft as a mini-game. You’ve got plants and you’ve got zombies…what makes this game so special?
