A prehistoric mass grave has been discovered near the ghost town of Adamana, Arizona. Centuries of horror now threaten to swallow the world unless your investigators discover what connects them.
"Operation Shallow Grave": Once Adamana, Arizona hosted tourists from around the world visiting the wonders of the Petrified Forest. Then in 1965, an act of esoterrorism left Adamana a ghost town. Now survey drilling for a new natural gas line nearby has uncovered the largest prehistoric mass burial site in North America. A paleoanthropology team out of Arizona State continues to uncover more bodies, all of them suggesting a sudden, violent death. Was it a disaster natural or unnatural? Something evil has been going on here, something dating back to the dawn of human civilization, and if the investigators don’t dig up the history of this nightmare in time, they may be doomed to repeat it.
