Cybermen's Lethal Gas Weapon

Krang orders technicians to pump this Cyberman gas into enclosed spaces (e.g., the Radiation Room and human hiding areas) to eliminate resisters. The gas serves as a chemical weapon deployed through ventilation systems, creating choking hazards that force desperate ultimatums (e.g., surrender the warhead or suffocate). Haines and Dyson ambush Cybermen with radioactive rods to prevent full deployment, while Ben Jackson exploits the gas-filled environment to ambush Jarl. The lingering gas highlights Cyberman ruthlessness and tactical flexibility in siege scenarios.
