Imagine an electric microwave with the door detached, and a focusing element. Now you can boil whatever water you point your gun at! Even if that water is in someone's blood.

The microwave gun requires electricity and only works at short range, but it is able to induce rapid heating of the materials the beam crosses. Wearing metal armor? Now you're wearing your own personal furnace.
