Atmosfear (previously known as Nightmare in certain regions) is an Australian[1][2] horror video board game series released in 1991 by Phillip Tanner and Brett Clements.
Two years after the game's launch in 1991, the two millionth Nightmare board game was sold. Since then, three game expansions have been released.
A major refresh to the series was released in 1995, titled The Harbingers, which sold above the industry's sales predictions in Australia and became one of the top-ten best-selling games in the United States and the United Kingdom within months of its release.
The series was revived in 2004 with the release of The Gatekeeper, which included a DVD to replace the video cassette which, with the addition of a programmed 'randomizer', allows the creators to give a whole new game every time the DVD is played. A second DVD board game was released in 2006 entitled Khufu the Mummy, acting as a direct sequel.
A new re-release of the 2004 game was released in 2019 with an app replacing the DVD.
On November 12, 2021, a successful 30th anniversary reboot was launched through Kickstarter.
