The Filtration Run

You are a maintenance janitor on the freezing, wind-swept frontier of TRAPPIST-1e. While the corporate elite lock themselves inside pressurized bunkers, a toxic, unidentified atmospheric gas has breached the main habitation module's filtration grid. The colonists in the lower decks are running out of time, and the air is turning to poison.\n\nThe only way to clear the air is to reach the manual scrubbers deep inside the blockaded engineering wing. But corporate security has sealed the bulkheads, ordered to protect proprietary assets and let the lower-tier workers choke.\n\nArmed only with your master keycard, your knowledge of the station's service ducts, and a toolkit, you must bypass the armed patrol. Every breath is a victory, and the clock is ticking.
