It is comprised of a long, narrow area with dashed lines to test range, three squid dummies, and grated platforms attached to the walls. A ramp from this area leads to a smaller section with nine squid dummies, six small and three large, to test weapon power. Three small dummies have Defense Up mains between one and three. The entrance to Ammo Knights itself is also visible from the Shooting Range; there's a door with two flickering signs above and beside it, along with boxes and what appears to be an early version of a Splat Charger.
