Quantic Dream's second title, Fahrenheit (Indigo Prophecy in North America) originally released for the PC, Xbox, and PlayStation 2 in September 2005. In 2007 it was made available as a download on the Xbox 360.
In 2015, the game was released in HD conversion, with the name Fahrenheit: Indigo Prophecy Remastered on PC platform distribution Steam and on PlayStation 4 via PlayStation Network.
Fahrenheit introduced elements—ethical ambiguity, romance, the inability to perish, and interactive storytelling—that would endure in Quantic Dream later games, like Detroit: Become Human.
In this paranormal thriller, New York City is stunned by a series of mysterious murders that follow the same pattern: ordinary people become possessed and kill absolute strangers in public. The main characters of the story must uncover the supernatural forces behind these crimes.
The first of Quantic Dreams titles to introduce both multiple playable characters (while Omikron: The Nomad Soul broached this aspect, the 'character' was always the player possessing a citizen of Omikron) and Quick Time Events (the player must match a series of images on the screen guiding actions with the controller, similar to the children's game of Simon Says). The game opens with the main character, Lucas Kane, inexplicably committing a brutal murder after savagely maiming his own forearms. Following the murder he is forced to go on the run while working to unravel why he killed a total stranger, untangle an ancient prophecy, and stop the world's temperatures from plummeting into a new ice age. Along the way he is pursued by two other playable characters, Carla Valenti, a police officer investigating the murder Lucas committed, and her partner, Tyler Miles.
Fahrenheit received generally positive reviews. On review aggregator Metacritic, the game has a 85/100 score on PC, and 83/100 on PlayStation 2. Critics praised it's innovative approach to game story telling while citing the awkward and sometimes painful QTEs as a partial solution to the question of innovative 'realistic' player interaction.
It won multiple awards and sold over one million copies.
