"This was me trying to draw from memory an old FNaF map I remember seeing.
It was dark besides some harsh blue light coming from the halls. Pirate's cove was made from map geometry, and had red curtains.

I think the video that I saw it from has been lost for one reason or another, but I never forgot it due to how eerie it felt to me.
Maybe it was an alpha version of the oldest map on Gmod. Maybe it was someone else's attempt that got buried. I don't know, but I hope one day I find out."
