At the end of the corridor, the jumpsuited figure turns towards you, the sound of metal boots clanking on the concrete floor as it turns. You bring your light up towards it and you're greeted with a wholly unexpected sight - it looks like a Cyberman - complete with the head handles - but it's a bit smaller, and it's wearing clothes over its metal exoskeleton, like this person was somehow converted from the inside out. It spots you and starts slowly trudging towards you, raising its arms as electrical energy crackles from its hands, as if it's preparing to shoot lightning at you.
