Blood leaked alpha - grayring (full level walkthrough)
Grayring is a level designed by Richard "Levelord" Gray in the leaked Blood alpha.
It's a castle map that is much larger than it looks when you start the map. The map has all sorts of areas, such as a tower to climb, a maze, a moat, a large gray area, a cave(?), and a small maze that contains a room with the Blue Oyster Cult's logo made out of floor sectors. It is also filled with what are clearly incorrect textures.
The "gray" in the map name is Levelord's last name, Gray. The levels with "gray" in their names are older than the ones with "gm" in them.
