Zero Line

In the city archive, an old map of St. Petersburg is discovered, one that is not found in any catalog. It marks streets, courtyards, and embankments that disappeared long before modern city plans were created. However, every morning the map changes: names, buildings, and entire neighborhoods vanish from it. Archivist Lida Severina is convinced that this is no ordinary document. Her great-grandfather, cartographer Arkady Severin, created what is known as the Zero Line — a secret route connecting places with the memories of the people who lived there. As long as someone remembers the history of a place, it remains on the map. When the memory fades, the city is erased along with it. An unknown individual under the name White Sheet has already connected to the system. He is removing layer by layer and claims that St. Petersburg needs to be freed from its heavy past. To stop him, you must journey through the city center, find ten signs of the Zero Line, and restore the message of the old cartographer. Each solved puzzle will return a part of St. Petersburg to the map — but in the end, you will have to decide which version of the city to preserve. Because sometimes erasing the past is easier than learning to live with it.
