Deep Saturation is a short analog horror game inspired by real limnic disasters. Navigate a fog-choked lake, deploy failing equipment, and document the depths with single-use cameras. What you capture may reveal more than you ever wanted to know.
Deep Saturation is a short dread-driven surface vessel horror game inspired by real-world limnic disasters and the claustrophobic terror of analog scientific equipment.
Set entirely on a weathered research vessel floating on a mysterious lake, you must navigate through dense fog to predetermined coordinates, deploy scientific equipment into the depths, and photograph whatever lies beneath the murky surface. Your only window to the underwater world is a primitive tethered camera that produces single Polaroid-style photographs - your sole source of visual information about what lurks below. There are no windows facing downward, no sonar imaging, no direct observation. You must rely entirely on analog instruments, coordinate navigation, equipment sensors, and the horrifying clarity of still photographs to complete your data collection mission. Success requires patience, scientific methodology, and the courage to keep looking when every instinct screams to stop.
Following the 1986 Lake Nyos disaster in Cameroon, where a limnic eruption killed over 1,700 people in their sleep, international monitoring protocols were established for similar geological formations worldwide. For decades, these systems remained dormant, relegated to automated data collection and routine maintenance. Then came the Deep Saturation Incident. Satellite monitoring detected CO2 signatures matching the pre-eruption patterns of Lake Nyos - but magnified beyond any previously recorded levels. The lake, absent from official geological surveys and showing impossible depth readings, began exhibiting thermal anomalies that defied conventional understanding. A hastily assembled research consortium deployed the "Deep Saturation" monitoring station - a single-operator vessel equipped with deep-water sensing equipment. The mission parameters were deliberately minimal: collect data, document anomalies, transmit findings. What they didn't mention was why the previous three monitoring teams had gone silent. You are a limnologist specializing in dissolved gas dynamics. Alone on the research vessel with failing equipment and increasingly disturbing data, you must photograph the lake's depths and transmit your findings to a facility that may no longer exist. Navigate through the fog, deploy your equipment, and document what lies beneath. Try to complete your mission before the lake claims you too... or before you discover why the others never returned.
"The lake remembers what we choose to forget. Every measurement brings us closer to understanding... and further from safety."
