This topic might have a better name.
Person who put this template here can't confirm if the exact name was used in Nightmare, but if it is, wouldn't the "Cyber" be capitalised?

The anti-Cyber gun was a weapon used by the punishment platoon led by Alice Ferrin. When fired, the gun produced a red beam which disintegrated Cybermen into thin air. The gun only had a number of shots before it needed to recharge. Also, the Cybermen installed an upgrade which rendered the gun useless. (TV: Nightmare in Silver)
