Suda51’s The Silver Case will be releasing in April for PS4 18 years after the game debuted on the original PlayStation in 1999. Now NIS America has confirmed that the PS4 version of The Silver Case will receive two additional chapters, these being called Yami and White Out Prologue. Yami is set some months after the last main chapter of The Silver Case, acting as a final conclusion. White Out Prologue is set years after to link The Silver Case with sequel The Silver Case: Ward 25.
The PS4 version of The Silver Case will also have two new music tracks as well as twelve remixes done by Akira Yamaoka, Erika Ito and the Grasshopper sound team.
