Closed Nightmare
Story. The player assumes the role of Maria Kamishiro, who awakens in an unknown location without her memories and with her left arm paralyzed. A mysterious person named Chizuru forces her to engage in a strange experiment in order to escape. While trying to find a way out, Maria meets with Eito Ginjo and Jun Yagi, two survivors who are also captured and locked up in the same location. They're being stalked by hostile masked people from the dark. Gameplay. The gameplay system has four parts: movie, text, exploration, and gimmick. Movie portions consist of live-action  first-person cutscenes. Text portions require users to select options which may alter story progression. Exploration involves the player examining their surroundings. The player will then apply what they have learned during exploration to the gimmick portion to solve various challenges. Development. The game was initially revealed as "project Nightmare" in January 2018. In April 2018, Nippon Ichi Software revealed the final title of the game and released a teaser trailer showcasing live-action footage from the game. Promotion. To promote the game, NIS released a Closed Nightmare smartphone game called 360° Escape Game which is now available for  iOS and Android. A campaign was featured that for anyone who can finish the game in 15 seconds or less, players would be able to enter their name into a raffle to get a free copy of the game. The campaign ended on July 15, 2018.
