Located on the top of a mountain, the guidestones consist of one upright standing, central stone slab in the middle and four standing slabs around it. The central slab has a horizontal stone on top of it, while the outer slabs have petroglyphs on both their front and back sides.
In Nifskope, the author of the Mysterious Guidestones is Connor McCampbell.
The Mysterious Guidestones closely resemble the real-world Georgia Guidestones, a stone monument created in 1980 that functioned as a durable compass, calendar, and clock. The slabs of the Georgia Guidestones provided ten principles written in eight different languages, often theorized to be instructions for rebuilding civilization after an apocalypse. Three years after the release of Wastelanders, the Georgia Guidestones were damaged in a bombing and subsequently demolished.
