The Harbingers is an Australian video board game designed by Brett Clements and Phillip Tanner and published by Mattel as a major update to the Atmosfear series. The object of the game is to collect six different coloured "Keystones" and thus beat the "Gatekeeper". Before players can start collecting Keystones they race each other, each seeking to become a "Harbinger". Players who fail to become Harbingers within ten minutes must play the main game as "Soul Rangers"โmiserable scavengers who obey their own rules.To beat the Gatekeeper, players must face their worst fear. If none of players is able to win the game within sixty minutes, the Gatekeeper is the winner.
