The information appeared on Reddit. The author of the post claims that it is not a full-fledged remake, but an updated version of the original Ryse: Son of Rome on Crytek's proprietary engine. According to him, the information was obtained from industry sources.
Insider Daimler_KKnD also recalled his past statements, which included rumors about Forza Horizon 6 in Japan and a canceled MMO from ZeniMax.
For now, the information should be treated with caution. Neither Xbox nor Crytek have officially confirmed the existence of the project.
However, the return of Ryse seems logical. The game was remembered as one of the most spectacular projects in the Xbox One launch lineup, but the franchise never received a sequel and gradually faded from the spotlight.
