yes kinetic energy, but it is stored in shotgun shells. personally id rather have Ruby's weapon from there, but i like sniper rifles
you mean like how any firearm works??? (kinetic energy)
And this is the problem with things from anime and other works of fiction. They describe things that make no sense in the real world.
Kinetic energy is a fancy way of saying "It moves". A bullet is moved through the air from the explosive force of the propellant that is burned by the priming cap....
Or, a falling object is instilled with kinetic energy from gravity pulling it to the ground.
A fist has kinetic energy from the muscles moving it through space.

Namikaze is correct, you can not make this weapon in SR, (or any game that obeys the laws of physics)
