A beta test began June 5, 2026, and runs until an early access launch planned for autumn. The tool supports Windows, web, iOS, and Android export, and includes AI-powered translation. It is led by Yutaka Owada, a CyberStep founder.","whyItMatters":"RPG-Cobo enters a crowded field of game-making tools as a fully open-source, commercially usable package with modern graphics features, potentially lowering the barrier for indie developers who want high-fidelity voxel-based RPGs.","webCardHtml":"\u003cp\u003eSuper Shark released the beta of RPG-Cobo on June 5, a development tool that packages voxel rendering, PBR, global illumination, and post-effects into a single open-source application under the Apache 2.0 license. The tool allows commercial use and redistribution of both the software and its bundled assets, and supports plugin-based expansion. Export targets include Windows, web browsers, iOS, and Android. The beta period will include a contest with prizes, and early access is scheduled for autumn 2026. Yutaka Owada, a founding member of CyberStep and director on titles such as GetAmped and Onigiri, led the project after leaving CyberStep in 2024.\u003c/p\u003e","blueskyPost":"RPG-Cobo is open-source, which sets it apart from most RPG makers. Owada, a CyberStep founder, brings voxel tech from a game-dev background, not a tooling one.","twitterPost":"RPG-Cobo is open-source with voxel graphics, led by a CyberStep founder. That combo is rare in RPG tooling.","threadsPost":"RPG-Cobo is open-source, which is unusual for a commercial RPG tool. It also uses high-res voxel graphics and PBR rendering. The lead, Yutaka Owada, founded CyberStep, a game studio, not a middleware company. That background may shape how the tool handles performance and export targets.","newsletterBlurb":"Super Shark announced RPG-Cobo, an open-source RPG development tool with high-resolution voxel graphics, PBR rendering, and global illumination.
