S.D.M.G.

The S.D.M.G (or Space Dolphin Machine Gun) is a straight upgrade from the Megashark, with a slightly faster firing rate and same ammo usage bonus, but with a noticeably higher damage output. Its abilities are similar to those of the Chain Gun, but it is more precise, deals significantly more damage, and has a slightly lower rate of fire.

It can be dropped by the Moon Lord.

The S.D.M.G. has a base 14% critical strike chance as opposed to the usual 4%.

The best modifier for the S.D.M.G is Unreal.
