In the original game, sounds are installed at the coordinates, but these sounds are dummy. If you look at the source description of the sounds, you can understand what kind of sounds should have been there. Based on this, I inserted the most appropriate sounds in these places.
Which places got new sounds?
Market in Chinatown;
At the Bistro Marco restaurant;
At the docks (ship whistles);
Notification at metro stations;
Reloading the rocket launcher.
Requirements: Game version - any PC version.
Thanks Fire_Head for the IIITrainAnnouncement.asi plugin, which brings back the function of sounds on stations.
