Object
Corwyn's Blaster
Jamie pulls this handheld blaster from the dead crewman sprawled in the oxygen supply room and hands it to Gemma Corwyn with a direct 'You'd better take that' for defense. She grips it tightly during their tense split, then fires it in the Operations Room at an advancing Cyberman. The energy blast strikes true, halting the metal invader for a moment before its counterattack drops her dead.

Purpose
Fire energy blasts to slow or stop Cybermen in close combat
Significance
Corwyn's brief success with it buys seconds against the Cybermen but ends in her death, exposing the crew's weapons as inadequate against the invaders and forcing the Doctor into deeper helplessness as the station falls.
