<P> Detroit: Become Human had a development budget of € 30 million . The game is based on Quantic Dream's 2012 PlayStation 3 technology demonstration Kara, which received strong reactions and an award at the LA Shorts Fest . It starred Valorie Curry, who would later reprise the title role . Writer and director David Cage wanted to make the demo into a full game, despite not originally having planned to, because he was curious as to what would happen next . He took inspiration from Ray Kurzweil's The Singularity Is Near, which explains that the rate at which human intelligence develops pales in comparison to that of a machine . Therefore, Cage proposes that machines may one day have emotions . Androids were designed with reference to artificial organs, how their energy would be generated, and human eye movement . An android's abilities were determined by each of their given profession . Experts in artificial intelligence were consulted to discern which technological advancements were the most feasible . Detroit was chosen as the setting to revitalise a city that had succumbed to economic decline after a historical contribution to American industry . The developers travelled to Detroit to conduct field research, taking pictures, visiting abandoned buildings, and meeting people . </P> <P> In late 2013, Cage was in preproduction on Detroit: Become Human which he said would build upon his work on Heavy Rain and Beyond: Two Souls . Cage's script--between 2,000 and 3,000 pages--was first relayed to the design team whilst the programmers created the graphics as well as a new game engine with advancements in features like rendering, dynamic lighting, shading, bokeh, and physical cameras . Quantic Dream improved their game engine's depth of field after Mark Cerny, lead architect of PlayStation 4, came to evaluate it . In October 2016, the screenplay was completed after more than two years . Cage used charts and diagrams while writing the choices, to see where they would end up; penning "five or six thousand pages of notes", he likened the story to a Rubik's Cube . Two scenes were cancelled over their lack of clarity in how violence was portrayed . The casting extended to Los Angeles, London, and Paris in search for more than 250 actors to portray 513 roles . The actors were scanned in 3D, whose models were then made into characters . Shooting and animation followed, and on 8 September 2017, the performance capture was finished after 324 days . Detroit: Become Human was worked on by the 180 staff members at Quantic Dream and also outsourced to the Philippines, China, Vietnam, and India . The game has 35,000 camera shots, 74,000 unique animations, and 5.1 million lines of code . </P> <P> The characters Connor and Markus are played by Bryan Dechart and Jesse Williams, respectively . Clancy Brown, Lance Henriksen, and Minka Kelly portray supporting characters Lieutenant Hank Anderson, Carl Manfred, and North, respectively . There are three different composers, one for each playable character: Philip Sheppard for Kara, Nima Fakhrara for Connor, and John Paesano for Markus . Sheppard's cello sequence in Kara's theme was inspired by the flames of a log fire, whereas the motif layered over it came from the two syllables in her name . Fakhrara created custom instruments and used vintage synthesizers in order that the sound could represent the robotic nature of Connor . Paesano's music was made with the idea that it would be "like a church hymn", personifying Markus' transformation into a leader . Sheppard recorded at Abbey Road Studios with the English Session Orchestra; Paesano was at Synchron Stage Vienna with the Synchron Stage Orchestra . Director of photography Aymeric Montouchet used "thick grain and shaky long lens" with shallow depth of field for Kara, "small, tight grain" and a blue palette for Connor, and orange and white colours for Markus . The game was released to manufacturing on 23 April 2018, after four years of production . </P> <P> Detroit: Become Human was announced on 27 October 2015 at a Sony press conference during Paris Games Week . It appeared at E3 2016 and E3 2017, showing trailers of additional playable characters and gameplay . Following E3 2017, Cage confirmed that the game would be released in 2018, later specified as the first or second quarter therein . The game was released on 25 May 2018 for PlayStation 4 . If pre-ordered, Detroit: Become Human would come with a dynamic theme and digital soundtrack, while the digital deluxe edition included a copy of Heavy Rain, a digital art book, digital soundtrack, two dynamic themes, and ten avatars . </P>
