This map is for fun only. It is a slightly redone map from the developers. The river overflowed its banks and fell upon the cities. Some sections of the route remained untouched, others completely went under water.
For driving under water, you need to use the ESBR or cars from mods in which the engine does not flood in the water!
Water has its own physics, so driving just does not work.
If this map will be popular, then in the future other official maps will be dipped into the water!
Any suggestions and criticism are welcome!
