"The plague sweeping across the nation has descended on the local mall, and it’s going to take more than rock bottom prices and ample parking to survive this threat!" Zombicide: Toxic City Mall is an expansion for Seasons One or Two. You have to band together to combat a whole new type of zombie, the Toxic Zombies. As these infected creatures are dispatched, they spray toxic blood at their attacker. Keeping a safe distance is advised!
