If you think that sending half a thousand (!) Nerf darts per minute at your target is unable to do enough damage, how about calling in the Mk 19 Nerf grenade launcher? This faithful reproduction of the Mk 19 grenade launcher that saw action in the military is belt-fed,. where it will fire Nerf rockets in lieu of live grenades (much to the relief of your target). Using batteries as its main source of power, it relies on compressed air to get its Nerf artillery to its target. The entire setup isn’t light though, tipping the scales at more than 100 pounds. You can’t purchase this off the shelf though since it is a DIY machine which probably won’t go on sale by its creator.
