Gauss Rifle or Rail Gun or Electromagnetic Pulse Accelerator.
works using a sigle magnet with scripts. Everything in collision group G will go boom near the gun.
Enter to fire. for the mech. look my other scenes.
feel free to use it.
Review and rate or I'll shoot you with my new Electromagnetic Pulse Accelerator.

edit:
in some cases "rail gun" is synonymous to gauss gun. but mostly no. you must be thinking about the ww2 german rail guns.
