The Silver Case is an adventure video game developed by Grasshopper Manufacture and published by ASCII Entertainment, originally released only in Japan for the PlayStation in 1999. A remaster of the game was released for PC in 2016, published by Playism, and for PlayStation 4 in 2017, published by NISA. The setting is contemporary Japan, and takes place in a universe which would later be used by Suda for later works. Within a city called the 24 Districts, a series of bizarre murders occurs, prompting the 24 Districts Police Department to send two detectives from their High-degree Murder Division to solve the case. The killings are soon linked to Kamui Uehara, a notorious serial killer who supposedly died several years before. The gameplay revolves around text-based situations, point-and-click mechanics, and interactive question and answer segments.
