At GDC 2025, Mythica announced plans for Sprocket Games and Unleashed Games to share different kinds of game-development materials through its platform: Sprocket’s procedural-generation technology and much of Unleashed’s art and game assets from Haven. The reports document an announcement of intent, not confirmation that the materials are available now.
What the studios announced
GamesBeat reported on March 19, 2025, with an update dated June 18, 2025, that the two studios would open-source key aspects of their projects through Mythica. Creative Bloq also reported the broad announcement on March 20, 2025. The contributions differ in kind: Sprocket’s is technology, while Unleashed’s is game art and assets.
GamesBeat described Mythica as infrastructure for hosting, sharing, and distributing open-source assets, binaries, tools, and game code where possible. That description does not establish what users can access on the platform today.
What Sprocket Games planned to contribute
Sprocket committed to open-sourcing procedural-generation technology, and GamesBeat reported that the studio had received an Epic MegaGrant for this work. The report does not name the technology, identify a repository, give a release date, or specify a software license. Those details are necessary to assess whether a particular tool is usable in a project.
#1 Best Overall
Josiah Kiehl, CEO of Sprocket Games, said, “Sprocket is built on a pile of excellent open-source tools.” He also said, “The more we, as an industry, embrace open-source initiatives, the faster we’ll get to the future we’re all trying to build.” These are the studio leader’s views on open source, not evidence of a specific tool’s capabilities or release status.
What Unleashed Games planned for Haven
Unleashed planned to begin by releasing much of the art and game assets from Haven. GamesBeat described the planned materials as entering the public domain, but that wording does not establish the rights status of every individual asset. The reports do not provide a complete inventory or asset-level release documentation.

- Check supported file formats, dependencies, engine versions, and integration requirements against your workflow.
- Look for documentation and maintenance information, and establish which materials are included versus retained by the studio.
What the announcement does—and does not—show
The announcement presented two different approaches to sharing game-development materials: procedural-generation technology from Sprocket and art and game assets associated with Haven from Unleashed. Mythica CEO Slater Victoroff framed the initiative as broader than code, saying, “This initiative isn’t just about sharing code – it’s about unlocking creativity for the next generation of developers.”
The reports establish those plans and the studios’ stated rationale. They do not establish a current catalog of releases, the exact contents of either contribution, or the permissions attached to particular files. A studio’s general open-source announcement is not a substitute for the license and documentation that accompany an individual release.
