Resident Evil 0, also known as Resident Evil Zero, is a survival horror video game developed and published by Capcom. It serves as a prequel to the original Resident Evil game, providing insight into the events leading up to the iconic mansion incident.

Set in 1998, the game follows two protagonists, Rebecca Chambers, a rookie member of the Special Tactics And Rescue Service (S.T.A.R.S.), and Billy Coen, a former Marine convicted of murder. The story begins as their paths cross on a runaway train infested with zombies and other mutated creatures created by the Umbrella Corporation’s sinister experiments.

Gameplay in Resident Evil 0 features the classic survival horror mechanics that the series is known for, including inventory management, puzzle-solving, and resource conservation. One unique aspect is the “partner zapping” system, allowing players to switch between Rebecca and Billy at any time to utilize their unique abilities and solve cooperative puzzles.

The game received praise for its atmospheric environments, tense gameplay, and challenging puzzles. It was also lauded for its improved graphics and updated control scheme compared to earlier entries in the series.

Overall, Resident Evil 0 offers an intense and gripping experience that will satisfy both fans of the franchise and newcomers alike, serving as a compelling addition to the iconic Resident Evil series.
