-gm_SectorB4 is map map set in an old indistrual area of city 14 precisely Sector b4.-
The map uses Counter-strike source texture so you'll need to have it mounted or it's content installed
-A small Sanbox scenic map that can be played in murder (>5 players otherwise it won't be fun) or anyother gamemode that doesn't require anything special like deathmatch/gungame/hideandseek/gungaym and many other
The alleyways and the main road are looking nice, perhaps the map is a bit too small.
However, I can't see it very well, but the sewer area under the little bridge seems a bit weird and "blocky" compared to the rest of the map. Maybe some displacements here and there could make it "smoother"...
