Konami released an update on June 26, 2026, for the psychological horror game Silent Hill f, adding a free collaboration costume named "Crimson Butterfly" based on Mio Amakura from Koei Tecmo's Fatal Frame: Crimson Butterfly Remake. The costume changes the appearance of protagonist Hinako Fukami to that of Mio Amakura, faithfully reproducing her outfit. The update is available at no cost to all owners of the main game and requires patch 1.20. The costume is purely cosmetic and does not include new scenarios, stages, or game modes. Alongside the update, a 50% off sale is running on Steam and the PlayStation Store for both Silent Hill f and Silent Hill 2. A bundle offering a discount on both Silent Hill f and Fatal Frame: Crimson Butterfly Remake is also available on Steam. Silent Hill f, set in a fictional 1960s Japanese town, has shipped over 2 million copies worldwide. Fatal Frame: Crimson Butterfly Remake is a full remake of the 2003 original, following twin sisters in a haunted village.
Developer Buttercup garden, operated by doko, released the 2D pixel-art adventure game 'Robot Hospice' for free on Steam on June 10. The game is set in a near-future facility where robots that have outlived their human families spend their final moments. The player takes the role of a new staff member named Midori, who interacts with five robots, each with distinct personalities, pasts, and memories. In one day, Midori can only talk to one robot, and repeated conversations build trust. The robots sometimes present difficult choices with no easy answers, and the player's role is to decide what is best for them to meet a peaceful end. There is one ending, but how the player parts with each robot depends on their choices. The game uses simple 2D dot-pixel art and Famicom-style music. As of the article's publication, about 10 Steam user reviews had been submitted, all positive. A browser version is planned for release around July. Doko cited childhood feelings toward pet robots and robot vacuum cleaners, and the novel 'Klara and the Sun' by Kazuo Ishiguro, as inspirations for the game's theme of hoping for a happy end for robots.
