It appears as though The Witcher 2: Assassins of Kings is the next Xbox 360 game to enjoy some additional enhancements, according to the Xbox Store. Credit to Reddit user SamFoote for the discovery.
As seen in the image below, and as reported by several other users from various regions, the listing clearly states that this game is enhanced for Xbox One X.
This is yet to be confirmed and announced by either Microsoft or/and CDPR, but with this coming directly from the store itself, it’s safe to assume that this is entirely legit.
The background art is from The Witcher 2: Assassins of Kings, and although the tiles within the image are from Wild Hunt, we suspect this will be remedied later today. Standby.
