Hejnał: an open-world game in contemporary Kraków

Field notes

The story follows courier Emil or Emilia Zaremba, who returns to Kraków after their father's death and finds a plan of underground shelters in a delivery. The site says the city uses an OpenStreetMap-based plan, with landmarks modeled separately; it names districts from the Old Town to Dębniki and Zabłocie. Its feature list also describes deliveries by bike or vehicle, pursuits, and multiplayer races.
