Resident Evil, originally released 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 Sony PlayStation in 1996. It was later ported for the Sega Saturn and Microsoft Windows platforms, and re-released for the Nintendo DS and onto the Sony PlayStation Network. Resident Evil was very well received critically and commercially, and has been credited with starting the modern survival horror genre. Its success spawned a multitude of sequels and spin-offs in the Resident Evil series.
Originally conceived as a remake of Capcom's earlier horror-themed game Sweet Home, development for the game was directed by Shinji Mikami, who took gameplay design cues from the 1992 game Alone in the Dark. Resident Evil establishes many conventions seen in later games of the series, such as the control scheme, the inventory system, as well as the iconic typewriter-based saving process.
