This modification adds to GTA 5 one of the cities (Naberezhny) from the Sarpinsky project. It is a small city with an embankment on the water.
This is a demo version of the project. There is no transport, boats and pedestrians. You can get there by helicopter or via SNT. Location of the city: next to the Lighthouse coast.
The archive in the ReadMe file indicates the installation process and coordinates.
