Rudkin’s fatal confrontation with Cybermats

Rudkin enters the Power Room and discovers Cybermats systematically sabotaging the Bernalium boxes, the station’s critical power source. His attempt to defend himself with a wrench fails as the Cybermats overwhelm him, their glowing eyes signaling their aggression. Desperate, he sprays one with quick-drying plastic, but the others retaliate, zapping his hands and rendering him defenseless. His screams alert Corwyn and Duggan in the corridor, who rush to investigate. The scene reveals the Cybermen’s escalating infiltration—no longer content with sabotage, they now target personnel directly—and establishes the Cybermats as a lethal, autonomous threat. Rudkin’s death becomes a turning point, forcing the station’s crew to confront the reality of the Cybermen’s presence and the urgency of their sabotage efforts.

Who Was There

Characters present in this moment

Cybermat
primary

None (as machines). Their 'aggression' is programmed—purposeful, relentless, and devoid of mercy. The glowing eyes serve as a chilling indicator of their single-minded focus: disable, destroy, and pave the way for the Cybermen.

The Cybermats swarm the Bernalium boxes in the Power Room, their metallic bodies scuttling with mechanical precision. When Rudkin enters, they immediately turn on him, their eyes glowing as they emit electric shocks. They systematically disable his attempts to fight back—first the wrench, then the plastic spray—before closing in for the kill. Their actions are coldly efficient, revealing their true purpose: not just sabotage, but elimination of obstacles to the Cybermen’s invasion.

Goals in this moment
  • To sabotage the Bernalium boxes (crippling the station’s power and defenses)
  • To eliminate Rudkin as a witness and potential threat to their mission
Active beliefs
  • The station’s defenses must be neutralized to facilitate the Cybermen’s invasion
  • Human resistance is irrelevant—it will be overwritten or destroyed
Character traits
Highly coordinated (attack as a unified swarm) Lethally efficient (target vulnerabilities and exploit them) Adaptive (shift from sabotage to direct assault when threatened) Emotionless (no hesitation or remorse in killing Rudkin)
Follow Cybermat's journey

Panic-stricken but determined, shifting to sheer agony as the Cybermats’ electric shocks render him helpless. His final screams are a mix of pain and frustration—knowing he’s failed to stop the sabotage.

Rudkin enters the Power Room and immediately spots Cybermats swarming the Bernalium boxes. He grabs a wrench and swings at them, but the Cybermats retaliate with electric shocks, forcing him to drop his weapon. In a final, desperate act, he sprays a Cybermat with quick-drying plastic, but the others overwhelm him, zapping his hands until he collapses in agony. His screams alert Corwyn and Duggan in the corridor, who rush to investigate.

Goals in this moment
  • To defend the Bernalium boxes (critical power source) from Cybermat sabotage
  • To neutralize the Cybermats before they can disable the station’s defenses
Active beliefs
  • The Cybermats are a direct threat to the station’s survival, requiring immediate action
  • He can outmaneuver or overpower them with available tools (wrench, plastic spray)
Character traits
Instinctively protective of the station’s systems Resourceful under pressure (attempts two different weapons) Physically vulnerable (overwhelmed by Cybermats’ coordinated attack) Defiant until the end (fights back despite hopeless odds)

Supporting 2

Alarmed and adrenaline-fueled, his initial curiosity about anomalies now replaced by visceral fear. The screams trigger a primal response—he’s no longer dismissing oddities; he’s confronting a direct threat.

Duggan is in the corridor adjacent to the Power Room when Rudkin’s screams pierce the air. He reacts instantly, rushing toward the Power Room alongside Corwyn, his alarm growing as the sounds of struggle intensify. Though he doesn’t witness the attack firsthand, his arrival signifies the crew’s belated realization of the Cybermats’ lethality.

Goals in this moment
  • To reach Rudkin and assess the threat in the Power Room
  • To support Corwyn in whatever action is needed (even if he lacks a clear plan)
Active beliefs
  • The screams indicate a life-or-death situation requiring immediate intervention
  • Corwyn’s medical expertise will guide the response (he defers to her leadership)
Character traits
Quick to respond to crises (rushes to investigate screams) Physically reactive (movement driven by urgency) Dependent on others for situational awareness (relies on Corwyn’s lead)
Follow Bill Duggan's journey

Sharp and focused, her alarm tempered by professional detachment. She’s transitioning from skepticism (about earlier anomalies) to urgent problem-solving, but the screams hint at a deeper dread—this is no mere malfunction.

Corwyn is in the corridor when Rudkin’s agonized screams cut through the air. She reacts with medical instinct, sprinting toward the Power Room with Duggan. Though she doesn’t yet understand the nature of the threat, her presence foreshadows the station’s shift from denial to action—she will soon demand answers and coordinate a response.

Goals in this moment
  • To determine the cause of Rudkin’s distress and neutralize the threat
  • To ensure no further crew members are harmed (prioritizing safety over immediate answers)
Active beliefs
  • The station is under a coordinated attack, and Rudkin’s screams are a symptom of a larger problem
  • Her medical and leadership roles require her to take control of the situation
Character traits
Commanding in crises (takes charge of the situation) Analytical even under stress (seeks to understand the threat) Protective of the crew (rushes to aid Rudkin)

Jamie's Quick-Set Plastic

The quick-drying plastic spray is Rudkin’s last-ditch weapon against the Cybermats. He grabs it from the Power Room shelf and sprays a Cybermat, hoping to immobilize it. However, the plastic fails to stop the swarm, and the Cybermats retaliate by zapping his hands, forcing him to drop the canister. The spray’s ineffectiveness underscores the Cybermats’ resilience and the crew’s desperate, improvised tactics in the face of an unstoppable threat.

The Power Room serves as the battleground for Rudkin’s final stand. Its humming machinery and confined space amplify the tension as the Cybermats swarm the Bernalium boxes. The room’s shelves, tools, and technical equipment—meant for maintenance—become weapons or obstacles in Rudkin’s futile fight. The Cybermats’ metallic scuttling echoes off the walls, creating a claustrophobic, high-stakes environment where every second counts. The room’s role shifts from a place of order to one of chaos, mirroring the station’s unraveling defenses.
