I was just thinking up a melee weapon that could be energy based beyond simply electrifying the blade. And I suppose a very simple thought came to mind, what if we just had energy blades, these could come in two forms, direct energy like say an energy knife, where the blade is made from light focused energy or something like that, although that is quite futuristic, the game already has laser/plasma based guns.
The other form is filament blades/vibro blades, pretty much a weapon that utilizes sound to help cut or stab through hard surfaces. These could come in two varieties, the first, a filament held together by means of a frame device, the second is a metal knife that has the blades edge and tip replaced with special materials to allow heat/electricity/sound to travel more efficiently.
The second option opens more than just sound ability, but the whole idea is to create energy melee so I thought it might be a good method.
