Well, it was on the main page of YouTube and Scolcer was live, I got into it and it was a mod that recreates the beta. I stayed watching and noticed that many of the maps in that mod are too accurate. It's incredible. There is even the "traincar" map, but only a little, but there is a map that was seen in a screenshot where I think there were some hecus shooting. WORSE is that there is the map that Brett Johnson showed on Tik Tok and it is complete. I know that they are alpha maps since They are extremely accurate for a recreation.

You can search for the mod in moddb but the page has been deleted but 1.0 has been rescued on a drive
