Custom Source Tools, used to compile Source Game Maps, Requires VTM: Bloodlines Alpha Testers, for the upcoming Beta 5 version of the tools.
  All you need is a map made in Valve Hammer 4's VMF format, and a copy of bloodlines 1.2, correctly setup with the assets, and some spare time to compile the map.
  Basically, I'm trying to see if the tools can support bloodlines, with the code update, or they get broken, and turn the maps into gibberish.
