Dreamfall Chapters is an episodic 3D adventure game with emphasis on character interaction, exploration of the game world, and puzzle solving. It is a sequel to the adventure games The Longest Journey and Dreamfall: The Longest Journey. The game was released for PC in five episodes between 21 October 2014 and 17 June 2016. The updated "Final Cut" version was released on physical media for PlayStation 4 and Xbox One on 5 May 2017, and the Microsoft Windows, OS X, and Linux versions on 21 July 2017. The Longest Journey series is set in two parallel universes: Stark, a cyberpunk future Earth, and Arcadia, its magical fantasy counterpart. Chapters takes place in 2220 CE and continues the story of Dreamfall, whose protagonist Zoë Castillo had uncovered a criminal conspiracy that aimed to enslave both Stark and Arcadia by stealing their residents' dreams. Although Zoë managed to disrupt the conspirators' plans, she was betrayed and left in a coma at the end of Dreamfall, and has to find her purpose in life again in Chapters. The writers described the narrative theme of the game as "chapters of life". Dreamfall Chapters was developed by Red Thread Games, an independent studio founded by Ragnar Tørnquist, who wrote and directed the previous two games. Funcom, the owners of The Longest Journey IP, had licensed the rights to develop the next installment out to Tørnquist's studio. Its development was crowd-funded by a Kickstarter campaign that raised over $1.5 million, with additional funding provided by the Norwegian Film Institute. The publisher Deep Silver released the game on consoles in 2017 to mixed reviews. Gameplay Dreamfall Chapters was originally developed on the Unity 4 game engine, but was retroactively upgraded to Unity 5 before the release of Book Four. It features large 3D environments, as opposed to 2D backgrounds in The Longest Journey and smaller 3D locations in Dreamfall. While not a completely open world, the game contains several free-roaming exploration levels, such as Europolis and Marcuria, and rewards players for exploring the levels and finding secrets. The locations themselves change slightly as the story progresses to reflect the passage of time. The player steers playable characters from an over-the-shoulder third-person view, using either the WASD keys and mouselook or a gamepad. Interactive characters and objects are highlighted on the screen, allowing the player to interact with them using the mouse and context menus. While the game
