Level-5 showed new footage for its crime suspense RPG Dekapolis at the online event LEVEL5 VISION 2026 II Dream, which streamed on September 10. The game follows rookie detective Harvard Marks, who investigates cases inside Decasim, a virtual space built as a full recreation of a real town. SCRAP, the company known for real escape games, is handling the original concepts for the case quests that appear in the game. A newly announced case quest titled The Three Mafia Murders is produced from a SCRAP original concept. Dekapolis is planned for PlayStation 5, Nintendo Switch 2, and Steam. The stream also carried the broader Level-5 announcement slate, which outlets covered as a single roundup.
SCRAP's involvement is framed as original concepts for the case quests, meaning the escape-game company's puzzle designs feed the quests rather than the main scenario. The announced example is The Three Mafia Murders, a case quest produced from a SCRAP concept. The stream ran at 21:00 Japan time on September 10 and appeared under the LEVEL5 VISION 2026 II Dream banner. Dekapolis is set in Decasim, a virtual world that copies reality, and its lead is rookie detective Harvard Marks.
Release date and price were not part of the September 10 stream. The title is listed for PlayStation 5, Nintendo Switch 2, and Steam, so no single platform is claimed. Both outlets that carried the news led with the same two items: the new footage and SCRAP's role in the case quests. One outlet attached the quest name The Three Mafia Murders directly to the SCRAP concept; the other named the setting, Decasim, and the protagonist, Harvard Marks, as the frame for the footage. None of the reports state how many case quests the game will carry or whether SCRAP's concepts cover all of them.
