Force Majeure II: The Zone

Predecessor

Was there a Force Majeure I? Yes, but it was not a computer game. Quote from the game's website:

Force Majeure I was a live role-play where participants physically enacted the first part of the story that was continued in Force Majeure II: The Zone. In the first installment of the series, people were trapped in utterly dark air-raid shelter for two hours, speculating and arguing about what had happened outside. The Zone is what happened outside.

Technology

Force Majeure II: The Zone was possibly the first adventure game to feature binaural beats which is a form of psychoactive sound programming, claimed to affect brain wave frequency patterns.

The game displays warnings before the start of such sequences and advise the player not to go through "if you are subject to any forms of seizure or epilepsy, using a pacemaker, are suffering of cardiac arrhythmia or other heart disorders or are taking stimulants, psychoactive drugs or tranquilizers."
