Mythica, an advocate for open sourcing game tools, announced that Sprocket Games and Unleashed Games will open source key aspects of their projects through Mythica’s platform.

This move represents from a major proponent of open source tech is one of the largest collective open source contributions in modern game development and signals a shift toward greater transparency, accessibility, and collaboration in the industry, the company said.

Somerville, Massachusetts-based Mythica made the announcement at the Game Developers Conference 2025 event.

Historically, game studios have kept their technology proprietary, but Mythica – having open sourced all of its tools – is driving a new movement. By open sourcing their games, these studios are taking a bold step to tackle some of the industry’s biggest challenges.

The open source move means artists can retain access to their work indefinitely, ensuring their contributions aren’t lost when projects end. Developers also don’t have to reinvent the wheel, allowing them to build on proven systems instead of starting from scratch. And smaller studios can develop bigger, better games, gaining access to high-quality tools and assets without massive budgets.

“This initiative isn’t just about sharing code – it’s about unlocking creativity for the next generation of developers,” said Slater Victoroff, CEO of Mythica, in a statement. “Just as open source revolutionized AI and software, it is now transforming gaming. By sharing these tools, developers can build on each other’s innovations, streamline production, and push the boundaries of what’s possible. We invite more studios to join this movement and help shape the future of game development.”

Sprocket Games and Unleashed Games are taking the first steps in this endeavor.  Sprocket has made a commitment to open source procedural generation technology and has received an Epic Mega grant to do so.  Unleashed will begin by releasing much of its art and game assets into the public domain.  

“Open source is the future of games and community engagement,” said Irena Pereira, CEO of Unleashed Games, in a statement. “When we fall in love with a game, our instinct is to create – whether it’s building within the world or expanding beyond it. By opening Haven to community contributions, we’re inviting players to shape the universe alongside our developers.”

While challenges remain, major studios are already exploring open source gaming. For example, Electronic Arts recently open sourced multiple Command & Conquer titles, and Activision released the Caldera map from Call of Duty: Warzone for non-commercial use. With Mythica providing the infrastructure to host, share, and distribute open source assets, binaries, tools, and game code where possible, this movement is gaining momentum.

“Sprocket is built on a pile of excellent open source tools,” said Josiah Kiehl, CEO of Sprocket, in a statement. “From Linux infrastructure up through Mythica’s content generation tools. The more we, as an industry, embrace open source initiatives, the faster we’ll get to the future we’re all trying to build. Traditionally, studios have been behind the rest of the software industry in embracing openness, which I think is holding us back. My hope is that closed source platforms are increasingly relics of the past and platforms like Mythica’s are the standard for the future.”

Through partnerships with organizations like the Linux Foundation, Mythica is working to establish clear pathways for game developers to release their work in compliance with licensing restrictions while maximizing the impact of open source contributions. Studios like Sprocket Games and Unleashed Games aren’t just sharing assets – they are actively contributing to a broader ecosystem of procedural, generative, and modular development tools that benefit the entire industry.
