Due to the awful war in Ukraine, something that has put an immense amount of pressure on the devs, the Xbox One version of Sherlock Holmes: Chapter One has been indefinitely put on hold. The PS4 version is still on track for release.
Chapter One has managed to become the fastest-selling Sherlock Holmes chapter for Frogwares, especially having released on only the PC, Playstation 5 and Xbox Series X, with the last-gen versions still to come.
Sherlock Holmes: Chapter One is currently available on the PC, Playstation 5 and Xbox Series X|S. The PS4 version will be releasing on the 28th of April whilst the Xbox One version has been understandably put on hold.
