A Box of Cartridges is a type of ammunition found in various places within Derceto Manor. It provides the Rifle with eight additional shots. To use a Box of Cartridges, select the box from the inventory menu and press the Use option. An additional method involves selecting the Rifle from the inventory menu and pressing the Reload option. Upon selection of either method, the Rifle will become ready to fire. If the Box of Cartridges gets wet in the water areas near the end of the game, the item will be useless. If the Cartridges are loaded into the Rifle, they can still get wet.
