The game The Sinking City unfolds in America in the 1920s. A small town called Oakmont, in Massachusetts, was subject to a local cataclysm. Suddenly, the deluge slowly began to grow throughout the town. Most of the townspeople were evacuated at the first opportunity. However, a number of people remained in their homes — representatives of the city government, indigenous inhabitants, insane and other narrow-minded. In Oakmont, everything became aggravated also because strangers began to appear in the city, who found new houses on the flooded streets and trapped control over them. True, their appearance in the city is not a mere coincidence of circumstances, but a clearly planned act of action.
