Urban Legends: Oak Island Money Pit (2005)

From the Publisher:

What waits for you at the bottom of the Oak Island Money Pit?

This book, based on real events, takes you to the strange little town of Seaborough and neighboring Oak Island, both in Nova Scotia. A mysterious shaft, dug centuries ago and then filled and protected by ingenious traps, may hold the key to fabulous treasure, unlimited power, or unspeakable horror!

Who built the Money Pit? Pirates hiding the treasures plundered from ships across the coast of North America? The lost hoard of the fallen Knights Templar? Aliens? Escapees from Atlantis? Only the GM will know until the pc's reach the bottom and...pay dirt?

Oak Island has been populated with intriguing characters with in-depth background, each with possible plot twists that can take advantage of the various contents of the Money Pit.

As a bonus, this PDF comes with a supplement of tiled maps that can be printed before game play and used with miniatures.
