in case you don't know how to install maps, go to your steam/steamapps/common/cs2d/maps, drag and drop the .map file, launch the game up and you're good to go
and if for some reason you don't have it on steam.. it's probably a similar installation process, just go to your cs2d/maps directory drag and drop and you're done

if you haven't been living under a rock, by now, you should know who made fnaf. if not, i fear for you.

five nights at freddy's was made by scott cawthon

cs2d fnaf map revisualization or something by bette lightvale/h20d, either works.
