In Cave Story, Quote can collect many weapons, each differing in abilities. By gaining Energy Crystals that are in the shape of orange, shining small, medium and large-sized triangles, you can level your weapon up to 1, 2 and 3, 3 being the maximum. The level of which Quote's current weapon is at can be seen in the orange bar at the top left side of the screen. Energy crystals fall from enemies after their defeat, as well as certain containers. As Quote's weapon levels up, it's power, abilites and/or range change, depending on the weapon. Quote's experience lowers as he takes damage, so he'd have to continue collecting experience to manage his levels and keep them at the maximum. Due to the game's weapon trading system, the player will only ever carry five different weapons at a time.
