continuing the fine tradition of innovative not-really-a-guns in valve games, you clean that up with a special gun in HL3
anyway, a2 of koth_loggerheads. made some massive changes to the overall layout, such as blocking off the horrendous sightlines and making it so that you cant get from spawn to centre point in half a microsecond.
this building now contains the point. ive still not figured out doors for the trains, so there is one quite long sightline, though it is narrow and easily avoidable, and that'll be blocked off when i do figure out train doors
and here is the new layout, almost twice the size of a1, which was tiny.
worries: the area with the shipping container is too big and open. there are still long "vertical" sightlines from the upper ledges to the container areas. the building has made the point go from too open to too enclosed.
