Megashark

The Megashark is a Hardmode ranged, ammo-based weapon. It is a stronger version of the Minishark, and with 23 base damage it is arguably the strongest bullet-based weapon in the game (now superseded by the currently unobtainable S.D.M.G., and arguably the Uzi. The weapon fires at insanely fast speed and has a 50% chance to not consume ammo. It is one of the best weapons for use against Hardmode bosses.
