A map set in a british port town, this one took me about a year to make but I think it turned out really well. My favourite bits about the map are the lifting bridge and the pretty skybox (the bridge was a pain to set up though)
A small map set in a rail yard in city 17, there are 2 moving trains.
The first map I ever uploaded for gmod, its pretty barebones but I think it has a certain charm to it, the fog adds a lot of atmosphere imo.
