The Megalodon is a craftable Hardmode gun that is an upgrade to the Megashark and the Archerfish. When used, it rapidly fires bullets, with every other shot turning into a stream of water that does not consume ammo and pierces once. It also fires a short-range ring every shot which pierces once. Bullets and water jets deal 80% of the weapon's damage.

Its best modifier is Unreal.
