Way of the Samurai 4 was planned for release on PC via Steam last month, but U.K. publisher Ghostlight says some of the technical issues that came up during the QA process have forced them to push the release date back.
At present, Ghostlight hope to have Way of the Samurai 4 out on Steam by the end of March. Earlier this month, they wrapped up beta applications for the game, so progress is definitely being made on the project.
Way of the Samurai 4 was originally released for PlayStation 3. Developed by Spike Chunsoft, it places the player in 19th century Japan, with the arrival of Western naval vessels serving as a backdrop for your samurai’s adventures. You can read Siliconera’s impressions of the game at this link.
