Resident Evil Zero (GameCube, 2002) is a survival horror game developed and published by Capcom. It serves as a prequel to the original Resident Evil, exploring the events that led to the Mansion Incident. Players control Rebecca Chambers, a young S.T.A.R.S. medic, and Billy Coen, an escaped convict, switching between them to solve puzzles and survive against horrifying creatures. The game introduced the “partner zapping” system, allowing real-time character switching, and features detailed pre-rendered backgrounds and tense gameplay typical of the early Resident Evil series.
