H-3 Nozzlenose

"Listen up squids! This here is the H-3 Nozzlenose. You want a weapon that packs a wallop and also kind of looks like a garden hose rolled up? This here’s your pick. A long interval between shots is made up for by high attack power. With the H-3 Nozzlenose, a one-hit kill is a real possibility."
