"Nameless Me" Development team plans 2027 release, adopting motion capture for Yumiri Hanamori's voice acting.

"Nameless Me" Development team plans 2027 release, adopting motion capture for Yumiri Hanamori's voice acting. 3DM2026-09-2502:37:05 The development team for Nameless Me stated that Yumiri Hanamori's voice acting led them to adopt motion capture to capture the nuances of her performance. This adventure game, produced by Shueisha Games in collaboration with Historia, with planning and script by Takuya Yamanaka, has been delayed until 2027 and is planned for release on PC, Nintendo Switch 2, and PS5. At the Tokyo Game Show 2026, Shueisha Games set up a demo area for Nameless Me. The booth presented the game world using an elevator and walkable sets. General Producer Taichi Kawai stated that what happens inside the elevator is important in the game, so the team arranged this experience before the demo. The game revolves around four souls within a young girl, with players making choices through dialogue. Yumiri Hanamori voices all four souls and learned the full story early in development. Director Shun Sasaki said the team recorded her voice acting first, then found that the original character animations couldn't keep up with the emotions and subtle changes in her performance, leading them to add motion capture. The number of souls also underwent adjustments. Shun Sasaki revealed that the initial plan featured seven souls, but testers found them hard to remember; reducing it to three meant too few opportunities for individual choices, so the team finally settled on four. Takuya Yamanaka stated that the script was completely rewritten after this adjustment. For the voice acting, the team wanted to preserve the feeling of "four souls sharing one body," and did not ask Yumiri Hanamori to differentiate the characters solely by changing her voice. She gradually fleshed out each character's speech patterns based on their individual settings; Takuya Yamanaka served as the recording director and would make on-the-spot adjustments to the lines based on her understanding of the characters. Takuya Yamanaka also mentioned that the souls speak according to their own thoughts. The team considered adding a mechanic to detect lies through changes in eye contact but later decided to drop it. The game is currently scheduled for release in 2027.

Adventure game un:me announced for Nintendo Switch 2.

Adventure game un:me announced for Nintendo Switch 2. Today, Shueisha Games and Historia announced UN: Me for Nintendo Switch 2. The title is due out later in 2026. UN:Me is an adventure game. Players can expect to guide a girl harboring multiple souls within her body through an unsettling mental labyrinth. Find more details in the following overview: Your choices determine which soul remains. You alone will witness the consequences. A girl awakens in a mysterious labyrinth. Four voices echo within her mind. They are human "souls" drifting through this maze. Each of the four souls seeks to fulfill their own desires, attempting to seize control of the girl's body and act on their own will. What are these four souls, truly? Who created this enigmatic labyrinth - and why? Who is this girl? Through dialogue with each soul and by overcoming their individual traumas, you'll navigate deeper into the labyrinth. The answers await those who persist... Key Features * Unpredictably Shifting Selves: Within the labyrinth, souls hidden inside the girl seize control regardless of your intentions. Each soul possesses unique skills and traumas - with every switch, both visible dangers and available actions transform. Which "self" will surface next? You must navigate the maze while contending with these assertive souls. * Soul-Specific Traumas That Hunt You: Each soul carries unique traumas carved from their past. During exploration, the active soul's wounds react, destabilizing vision, senses, and movement as they assault the girl. * Dialogue Mode: Touching the Souls' Depths: Special items found in the labyrinth enable direct dialogue with individual souls. Memory fragments determine which souls you can reach and what questions arise - each item reveals different truths. Their words are sometimes fragmented, sometimes cryptic. Hidden within may lie hints for exploration or keys to the story's heart... * "Only One Can Remain" - Choosing and Erasing Souls: One body can harbor only one soul. The deeper into the labyrinth you venture, the heavier the decision becomes - which soul to preserve, which to erase. Can you accept the consequences of the souls your choices condemn? Fans can take a closer look at the game with the trailer below. Announcement trailer. Nintendonews'll pass along the release date when that comes in.
