In the absence of a new Deus Ex, indie imsim Tokyo Walled City may scratch that stealth ’n’ stolen passwords itch

Tokyo Walled City is an upcoming immersive sim from indie developer Grim Ronin, announced at Tokyo Game Show 2026. The game is described as a “stealth action retro-cyberpunk immersive sim with survival horror and RPG elements” set in a walled-off district of cyberized Tokyo.

Players take on the role of a knifey, parkour-capable mercenary navigating the dystopian urban environment. Gameplay centers on core immersive sim mechanics including quiet assassinations, environmental interaction, and player agency in completing objectives. A 0451 reference in the trailer signals the developers’ affinity with Deus Ex, positioning Tokyo Walled City as a spiritual successor to that franchise’s legacy of systems-driven stealth gameplay.

With its cyberpunk setting, stealth-focused mechanics, and emphasis on immersive sim design principles, the game appears tailored for players seeking a new entry in the vein of classic titles like Deus Ex. The combination of parkour mechanics, survival elements, and RPG features suggests a complex, player-driven experience that prioritizes multiple approaches and emergent gameplay over linear progression.
