Section Twelve (Oxygen Supply Compartment)

Tense and oppressive—the hum of life-support systems and the sterile lighting create a stark contrast to the violence of the dead crewman. The air feels heavy with dread, as if the room itself is holding its breath, waiting for the next move.

Discovery site and tactical staging area—where the team first encounters the Cybermen’s lethal handiwork and begins to coordinate their response. The room’s layout and contents (e.g., the video comms device, the emergency exit) enable the team to split their efforts and address the threat from multiple angles.

Represents the fragility of the station’s systems and the crew’s vulnerability. The oxygen supply room, a place dedicated to sustaining life, becomes a metaphor for the precariousness of their situation. The dead crewman’s presence turns it into a symbol of the Cybermen’s ability to infiltrate and disrupt even the most essential functions of the station.

Initially unrestricted, but the presence of the dead crewman and the Cybermen threat implies that the room is no longer entirely safe. The team’s urgency to leave and split up reflects their awareness that the oxygen supply room, like the rest of the station, is now a high-risk environment.

Oppressive and tense, with a sense of impending doom. The hum of the life-support machinery creates a low, rhythmic backdrop that underscores the urgency of the moment, while the dim lighting casts long shadows, amplifying the feeling of vulnerability. The air is thick with the weight of what’s at stake—the crew’s very ability to breathe—and the Cybermen’s presence adds a layer of cold, mechanical menace.

Battleground and witness point. The oxygen supply room serves as the primary location for the Cybermen’s sabotage, where Vallance inserts the silver capsules into the air supply system under the Cyberman’s direction. Simultaneously, it is the hiding place for Corwyn, who witnesses the sabotage and gathers critical intelligence to relay to the Doctor and the crew. The room’s functional role is thus twofold: it is both the site of the attack and the catalyst for the crew’s response.

Represents the fragility of human life and the Cybermen’s ability to exploit it. The oxygen supply room symbolizes the thin line between survival and extinction, as the station’s life-support systems—once a source of safety—are turned into weapons. It also highlights the asymmetry of power between the Cybermen and the humans, as the former can systematically dismantle the latter’s ability to survive with cold, calculated efficiency.

Restricted to authorized personnel only, though the Cybermen and their hypnotized agents (like Vallance) can move freely within it. Corwyn’s presence is clandestine, as she hides to avoid detection by the Cyberman.

Tense, claustrophobic, and filled with the hum of life-support systems, the room feels like a trap—isolated and vulnerable to the Cybermen’s infiltration.

Battleground and site of sabotage, where the Cybermen strike to eliminate resistance and compromise the station’s air supply.

Represents the station’s fragility and the Cybermen’s ability to infiltrate even its most critical systems.

Restricted to authorized personnel, but the Cybermen have breached these barriers, making the room a high-risk area.

Dimly lit and oppressive, with the hum of pipes and the eerie silence of a location where death has recently occurred. The room's isolation amplifies the sense of loss and the crew's desperation to counter the Cybermen's threat.

Clue location where Gemma discovered the Cybermen's plan to poison the air supply. The room's oxygen tanks and pipes are critical to the station's life support, making it a prime target for sabotage.

Represents the crew's losses and the Cybermen's insidious infiltration. The room's connection to Gemma's death serves as a catalyst for Bennett's reckless actions and a warning of the crew's precarious situation.

Restricted to authorized personnel, with protocols in place to prevent unauthorized access or tampering with the oxygen supply.

Claustrophobic and tense, with an eerie glow from the lava lamps that amplifies the sense of danger and instability. The hum of machinery and the crackling static from the monitor add to the oppressive atmosphere, reflecting the high stakes of the Cybermen’s infiltration.

Battleground for the Cybermen’s sabotage efforts and a strategic location where the failure of their poisoning attempt is revealed, leading to the Planner’s directive for a full identity scan.

Represents the station’s vulnerability and the crew’s desperate struggle to survive the Cybermen’s infiltration. The room’s isolation and the eerie glow of the lava lamps symbolize the hidden threats lurking beneath the surface of the Wheel.

Restricted to authorized personnel, but currently under Cyberman control, with Vallance as the only human present.
