Rated M Resident Evil: Revelations is a 2012 survival horror video game developed and published by Capcom originally for the Nintendo 3DS handheld game console. Set shortly after the events of Resident Evil 4, the game follows counter-terrorism agents Jill Valentine and Chris Redfield as they try to uncover the truth behind a bioterrorist organization that plans to infect the Earth's oceans with a virus. The game features a single-player mode where the player must complete a series of episodes that involve solving puzzles and defeating enemies, and a multiplayer mode where players may fight their way through altered single-player scenarios. A high-definition (HD) version was released for Microsoft Windows, PlayStation 3, Wii U, and Xbox 360 in 2013, and for PlayStation 4, Xbox One, and Nintendo Switch in 2017.
