Ben’s solvent attack on a Cyberman

In a high-stakes gambit, Ben exits the airlock into the lunar vacuum, armed with a solvent-filled cylinder. He hurls it at a Cyberman’s chest unit, shattering the glass and releasing a corrosive vapor that begins dissolving the creature’s metal plating. The attack exploits the Cybermen’s vulnerability to acetone, forcing the Cyberman into a disoriented, flailing state as its systems degrade. Ben quickly re-enters the airlock with Benoit, sealing the outer doors behind them. The temporary reprieve underscores the desperation of the moonbase’s defenders, as the broader Cybermen threat remains unresolved. The scene highlights Ben’s willingness to take extreme risks—despite the untested nature of the solvent—and the brutal efficiency of the Cybermen’s technological weaknesses. The moment also serves as a tactical victory, restoring morale and proving that the humans can fight back, even if only briefly.

Determined and focused, with an underlying tension that reflects the high stakes of the moment. His urgency is palpable, but his actions are precise and controlled, driven by the need to protect his companions and the moonbase crew.

Ben exits the airlock into the lunar vacuum, armed with a solvent-filled glass cylinder. He throws it with precision at a Cyberman’s chest unit, shattering the glass and releasing a corrosive vapor that begins dissolving the Cyberman’s metal plating. The Cyberman flails in disarray as its systems degrade. Ben quickly re-enters the airlock with Benoit, sealing the outer doors behind them to escape the vacuum and the dissolving Cyberman. His actions are swift, calculated, and driven by the urgency of the situation.

Goals in this moment
  • Exploit the Cybermen’s vulnerability to solvents to disable or destroy the Cyberman outside the airlock.
  • Ensure the safety of Benoit and the moonbase by quickly re-entering the airlock and sealing the doors.
Active beliefs
  • The solvent will effectively corrode the Cyberman’s chest unit, giving the defenders a tactical advantage.
  • Every second counts in the lunar vacuum, and hesitation could be fatal for both him and Benoit.

The Cyberman exhibits no emotional response, but its mechanical systems are visibly degraded and malfunctioning. Its flailing movements indicate a loss of control and functionality, driven by the corrosive effect of the solvent on its chest unit.

The Cyberman is targeted by Ben’s solvent-filled glass cylinder, which shatters upon impact, releasing a corrosive vapor that begins dissolving its chest unit. The Cyberman flails in disarray as its systems degrade, its mechanical body failing under the chemical assault. The attack forces it into a state of disorientation and vulnerability, highlighting the Cybermen’s weakness to acetone-based solvents.

Goals in this moment
  • Maintain operational integrity and continue its mission to control the Gravitron and destroy Earth.
  • Resist the corrosive effects of the solvent to avoid system failure.
Active beliefs
  • Its mechanical superiority and invulnerability are absolute, despite the evidence of its degrading systems.
  • Human resistance is insignificant and will ultimately fail against the Cybermen’s collective.
Character traits
Vulnerable to chemical corrosion Mechanically precise but rigid Lacking emotional response to pain or failure Operating under cold logic, even in distress

Relieved to have successfully re-entered the airlock and sealed the doors, but still tense due to the ongoing Cybermen threat. His focus is on ensuring the safety of the moonbase and its crew, and he trusts Ben’s improvisational tactics.

Benoit enters the airlock alongside Ben, exiting briefly into the lunar vacuum to support him. He quickly re-enters the airlock with Ben and helps seal the outer doors, ensuring their safety from the vacuum and the dissolving Cyberman. His actions are coordinated and efficient, reflecting his technical expertise and the urgency of the situation.

Goals in this moment
  • Assist Ben in executing the solvent attack and ensure their safe return to the airlock.
  • Seal the outer doors to protect the moonbase from the lunar vacuum and the dissolving Cyberman.
Active beliefs
  • Ben’s plan to use the solvent is their best chance to disable the Cyberman and buy time for the moonbase.
  • Every action must be precise and timely to avoid compromising the airlock’s integrity or their safety.

Acetone Solvent Cylinder (Polly's Formula)

The solvent-filled glass cylinder is the improvised weapon Ben uses to exploit the Cybermen’s vulnerability to acetone. He hurls it at the Cyberman’s chest unit, shattering the glass and releasing the corrosive vapor that begins dissolving the Cyberman’s metal plating. The cylinder’s sturdy glass construction ensures it survives handling until the targeted strike, where it fulfills its critical role in disabling the Cyberman. Its use is a testament to human ingenuity in the face of overwhelming mechanical threat.

Before: Filled with Polly’s acetone-based solvent, securely held by Ben in the airlock, ready for use as an improvised weapon.
After: Shattered upon impact with the Cyberman’s chest unit, its contents released and the glass fragments scattered on the lunar surface. The cylinder is destroyed in the process of fulfilling its purpose.
Moonbase Airlock Outer Doors (Armored Entry System)

The moonbase airlock’s outer doors serve as a critical barrier between the lethal lunar vacuum and the pressurized interior of the moonbase. Ben and Benoit slam the doors shut after re-entering the airlock, sealing out the vacuum and the dissolving Cyberman. The doors’ sturdy mechanisms hiss into place under their desperate hands, providing a fleeting but vital stronghold against the Cybermen’s invasion. Their function is both practical and symbolic, representing the thin line between survival and annihilation for the moonbase defenders.

Lunar Surface (Moonbase Perimeter)

The lunar surface serves as the battleground where Ben executes his solvent attack on the Cyberman. The airless, barren expanse of regolith stretches around the moonbase, providing a stark and unforgiving backdrop for the confrontation. The low-gravity environment allows Ben to move swiftly but also underscores the lethal nature of the vacuum, where exposure means certain death. The Cyberman’s flailing as its chest unit dissolves is a silent, eerie spectacle in the vacuum, where no sound can carry. The lunar surface is both a physical obstacle and a metaphor for the isolation and desperation of the moonbase defenders.
