The Neutrino 3000 is an invention of the Centaur Foaly. It was a major improvement on the Neutrino 2000. It had five or more settings, and had a strong plastic casing. It had no metal parts, was powered by kinetics, with a back-up nuclear battery. One security breakthrough was that of fingerprint recognition. When someone first grasps the gun, it can be used by he/she and only he/she. The gun also records shots, which made it much easier for Ark Sool to believe that Holly Short murdered Commander Julius Root.
