Blood leaked alpha - graykeep (full level walkthrough)
Graykeep is a level designed by Richard "Levelord" Gray in the leaked Blood alpha.
It's a huge map that focuses on a castle in a moat. There's a large river area, a big yard outside the castle, plenty of interiors in the castle, and more.
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.
