In December 2010, the thriving city of Del Ray—built along the Hudson River—prepares to celebrate the opening of Geo City, a massive underground metropolitan complex heralded as the safest ever built. Days of relentless rainfall push the river beyond safe levels, triggering a precautionary evacuation order that quickly spirals into full-scale catastrophe. Players inhabit multiple survivors, each forced to improvise their escape using whatever resources the flooded city provides. Body temperature plummets in soaked clothing and cold air, demanding constant shelter-seeking and scavenged meals. Running, climbing, crawling, and jumping through a devastated urban landscape, each character pieces together clues from emergency broadcasts and fellow victims, slowly unraveling the broader disaster as they fight to reunite with their families.
