A boardgame set in the Dungeons & Dragons Underdark campaign setting. Each player starts with a party of six adventurers attempting to acquire and return with the Underdark Maps. The game is played on a 40 space track. The first party to reach the end of the track obtains the Underdark Maps. That party must then return the Maps to the start space to win. However, if an opposing party is able to defeat the party carrying the Maps, then the victorious party obtains the Maps and may return them to the start space to win the game.
