Actually found this whilst looking for TTT maps but nostalgia again http://steamcommunity.com/sharedfiles/filedetails/?id=767908827&searchtext=
My first looks opinion : Looks like someone's first map. Although I'm going to check it out. Will edit with more pictures and stuff in a sec
One problem though, it says it's not a valid bsp file. After doing research this thing was a port from Gold Source (Goldsrc) Gold source games stopped being made in 2006. So this map is either really old, or someone made a map for old cs 1.6 (which is unlikely) because CSS was the next form of deathrun, and was ever so popular than 1.6 http://gamebanana.com/maps/187236 Couldn't find it in my files to change the name, but here's more pictures on gamebanana
