You can play as zombies in Plants vs. Zombies: Garden Warfare. There are four zombie classes, including, adding a scientist and engineer to expected ones, like a ranger and an all-star. I love that the Engineer rocks a plumber's crack. Think of the zombie classes as more and different ways to get brains.
Plants vs. Zombies: Garden Warfare gets a exclusive mode called Boss Mode. A trailer revealed at EA's gamescom press conference showed off this SmartGlass feature that has you sitting back and pointing, making gestures to control zombies, doing so from the comfort of Crazy Dave’s RV or Zomboss’ Blimp. You'll make things explode with Zombomb strikes, too.
