This is a small gmod map by Sputnik53.This map has been designed off of the authors own imagination of what his own secret hideout would be like. It is based on a remote island with no supplies (The idea is that you bring your own, in other words spawn them) this island has a small elevated shack with a pier. The shack is small inside and it already has a TV aerial pre-installed for broadcasting your evil taunts to the forces of justice (Or just watching the game with a bud). This map is good for comics/general gmodd'ing. And is pretty well detailed. Start your evil plans today!
