probably one of the best weapons you can get in zombies. 3 shots (6 if pack-a-punched), wipes out 10 + zombies from my own experiece per shot, so great for clearing out those mobs. dangerous if too close however because you CAN shock yourself AND teammates. they will not be happy if you do this. the relaod is rather sluggish, so try to get sleight of hand ASAP to get the most outta your zap cannon! works well on hellhounds too. try to conserve this till you need to use it because this gun is a life-saver, and you kinda want to have reserve ammo in your life-saver gun when you need to save a life or 2!
