Airlock Air Supply Cylinders
Portable containers originally designed for air supply but repurposed as signaling devices in a crisis situation
1 appearances
Purpose
To serve as improvised percussion tools for creating audible signals when trapped, converting the characters' dwindling energy into noise to attract external attention.
Significance
These cylinders embody the crew’s failing resources—once functional components of the airlock's fail-safe system, now reduced to useless weight in their fight for survival. Their misuse highlights how tactical errors (shouting and banging) accelerate oxygen depletion, directly contributing to the Master’s eventual trap.
