- “Very rare collection of Quayola's Brown Spectrum Quayons in excellent condition.”
It is found in the Ghost Hideout. After taking the quest "Missing Person" from the Job Board in Wellspring and entering the Ghost Hideout, the box is found to the left from the entrance and upstairs. The box is sitting at the bottom of a blocked off flight of stairs at the dead end. This video shows the way.
- It is a reference to the mainstream critic that Quake featured too many brown tones. This critique was referenced by Ben "Yahtzee" Croshaw in his Zero Punctuation review video of Clive Barker's Jericho, claiming: "id software's original Quake […]. I'm sure with the benefit of hindsight we can all agree that Quake wasn't exactly easy on the eye. Which was your favorite Quake level? The brown castle, the greenish brown temple or the other brown castle?"
- It is also a reference to Crayola Crayons.
