Discover all 10 weapons in Cave Story, their unique leveling systems, stats, locations, and how to best utilize them for maximum damage and effectiveness.
Cave Story features a unique weapon leveling system. Collecting energy crystals dropped by enemies grants experience to your current weapon. Filling the experience bar levels up the weapon, usually making it stronger. Taking damage can cause you to lose experience and potentially level down. All weapons start at level 1 and typically max out at level 3, with a "damage buffer" at MAX experience to prevent easy level-downs. However, the Blade, Spur, and Nemesis have different mechanics. Players can only carry a maximum of 5 weapons due to a trading system, making weapon choices crucial for later stages.
The following explains the stats provided for each weapon:
- damage: Amount of damage dealt.
- range: How far the weapon shoots.
- speed: Speed of the projectile.
- rate: Maximum number of shots on-screen simultaneously.
- exp: Experience needed to reach the next level (or MAX for level 3).
