Resident Evil Zero HD Remaster is a remastered version of the 2002 survival horror, developed and published by Capcom for the PlayStation 4, PlayStation 3, Xbox One, Xbox 360 and PC. It serves as a prequel to the first Resident Evil, covering the ordeals experienced in the Arklay Mountains by the S.T.A.R.S. Bravo Team. The gameplay remains similar to other entries in the Resident Evil series, but includes a unique "partner zapping" system. The player controls both S.T.A.R.S. officer Rebecca Chambers and convicted criminal Billy Coen, switching control between them at will in order to solve puzzles and take advantage of their unique abilities.
