Resident Evil, known in Japan as Bio Hazard (バイオハザード, Baio Hazādo), 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. 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 City following 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.
Originally conceived as a remake of Capcom's earlier horror game Sweet Home, Resident Evil became its own project with development led by Shinji Mikami. Mikami took gameplay design cues from the 1992 game Alone in the Dark as well as aesthetic design from The Shining (1980) for the scenery. 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.
