Mechalodon

The Mechalodon is a Hardmode, post-Duke Fishron ranged weapon and is an upgrade to the Megalodon. It fires at an insanely fast speed, has very slight inaccuracy, and fires a rocket every 50 shots. The rocket itself deals double the base damage of the weapon, and explodes on contact. Normal ammo used (e.g Musket Ball & Silver Bullet) will pierce through enemies, however specific types will not be affected (e.g Chlorophyte Bullet & Explosive Bullet). Like it's predecessor, it is one of the strongest guns pre-Moon Lord. To add to the pile, rockets fired always deal a critical hit.
