[Dr.Disaster]

what reloads the revolver?

It's Special Attack.

What's unique about the revolver, is that it's the only gun that can be used with a shield or other weapon equipped.

I just plan to raise the base damage, to me this seems the best solution since I like the limited ammo. I think the problem was just that the damage wasn't good enough to overlook the drawbacks, but by getting rid of those drawbacks it would lose part of it's uniqueness.
