The zombie survivors are prepared for anything, with survival kits to defend against any zombie attack! For fast firing with no priming, take along the Nerf Zombie Strike Survival System Nailbiter blaster to fight zombies. Load the darts into the vertical indexing clip and pull the trigger to fire. The blaster’s 8-dart clip automatically indexes to the next dart and stays attached to the blaster. There’s no need to prime, so zombie fighters can unleash darts fast to keep the zombies at bay. The blaster includes 8 Zombie Strike darts.
