The Silver Case was an adventure game released on PlayStation in Japan back in 1999 from Grasshopper Manufacture and Suda51. The game was never released to western audiences, but that is about to change as The Silver Case Remastered launches on PC (Steam and Playism confirmed) this fall.
The first trailer was recently released and features scenes from the first chapter called Decoyman. There are also some new screens to go along with the trailer.
