What are you doing? Protect those plant seeds! When zombies get it in their heads they'd rather eat seeds than brains, the plant kingdom rallies together to form the Vegendary Heroes, a group of fearsome warriors dedicated to fighting off the invading undead. I Am Vegend: Zombiegeddon is the tale of this epic struggle, taking a tongue-in-cheek setting and sense of humor from games like Plants vs. Zombies and setting it in a two dimensional defense world.
