The game originally had an "80's filter" during production. According to director Hideo Kojima, it was inspired by the 2013 film Rush, which itself "had very 70's texture & tone of film." As the game's story was set in 1984, the team studied and developed a filter reminiscent of the 1980's. However, once it was used in fullscreen, it ultimately demanded too much processing power, slowing the game down significantly. This ultimately caused the feature to be removed in the final product.
