Resident Evil, known in Japan as Bio Hazard, is a survival horror video game developed and released by Capcom originally for the PlayStation in 1996, and is the first game in the Resident Evil series. It is Capcom's best-selling debut game, with sales of over 8.5 million copies worldwide. The game's plot follows Chris Redfield and Jill Valentine, members of an elite task force known as S.T.A.R.S., as they investigate the outskirts of Raccoon Cityfollowing the disappearance of their team members. They soon become trapped in a mansion infested with zombies and other monsters. The player, having selected to play as Chris or Jill at the start of the game, must explore the mansion to uncover its secrets.Conceived by producer Tokuro Fujiwara as a remake of his earlier horror game Sweet Home (1989), the development of Resident Evil was led by Shinji Mikami. Gameplay consists largely of third-person action with added emphasis on inventory management, exploration, and puzzle solving. Resident Evil establishes many conventions seen later in the series, including the control scheme, inventory system, save system, and use of 3D models superimposed over pre-rendered backgrounds.Resident Evil was very well received critically and commercially, and is often credited for defining the survival horror genre. It has since been hailed as one of the greatest video games of all time. Its success has spawned a multimedia franchise including video games, films, comics, novels, and other merchandise. The game has received dedicated ports to the Sega Saturn, Microsoft Windows, and Nintendo DS. In 2002, a remake of the same name was released for the GameCube featuring updated graphics, sound, and changes to the gameplay and story. A high-definition remaster of the GameCube game was released in 2015 for modern platforms.
