Instead of describing the mod right away, I'd rather talk a little about how it was made. As it often happens, the mod appeared just from an idea: often, when playing various racing games, I noticed that the locations in them were so good and picturesque (for example, what are the different country landscapes in Mercedes-Benz World Racing or Need for Speed: Hot Pursuit 2 from 2002) that you don't want to rush along all these beauties, but to examine them properly. But in a car simulator there is no time to consider the terrain, right? Of course, the streets of the night city from Need for Speed: Underground can hardly be called very picturesque, but there is something in them. Maybe it's because I really like this game. When I put it on recently to refresh fond memories, the idea came to my mind that it would be nice to somehow walk around this city, and not drive.
The only way I could implement this idea was to pull the location out of the game and paste it into GTA San Andreas for which I make mods.
