Background
Capcom initially conceived Resident Evil 0 in the late 1990s as a prequel to the 1996 original, aiming to explain the tragic downfall of the S.T.A.R.S. Bravo Team in the Arklay Mountains. Series creator Shinji Mikami wanted to implement a revolutionary "character zapping" system, allowing players to control two protagonists—Rebecca Chambers and Billy Coen—simultaneously.
Emboldened by this success, Capcom announced Resident Evil 0 as an N64 exclusive in 1999.

The key innovation was the "partner zapping" system—allowing players to switch between characters in real-time to solve puzzles.
