The Witness was originally announced as a PC/PS4 title, with an iOS version to follow at some point in 2016. However, it now seems that there may also be an Xbox One version in the works. The Entertainment Software Rating Board has recently rated the title for Xbox One, along with the already confirmed PlayStation 4 and PC versions.
A screenshot of the ESRB listing can be seen below.
Taking inspiration from Myst, The Witness gives player the opportunity to explore a large island that is home to several natural and man-made structures. The aim is to solve puzzles that are based on interactions with mazes presented on panels across the island. In order to solve these puzzles, players will be granted visual clues as they traverse the island. In addition, they’ll also get hints in the form of audio logs.
