In a significant move that challenges the status quo of the game development industry, veteran developer Dean Hall has unveiled "Brutal," an open-source C# game development framework. Developed through a collaboration between Hall’s studios, Ahwoo and RocketWerkz, the project arrives at a time of growing tension between independent creators and the dominant entities that control the tools of the trade. By offering a high-performance, royalty-free alternative to industry giants, Hall aims to shift the power dynamic back toward the individual developer.
The technology, which has been in active development since 2022, is designed not as a full-featured game engine, but as a lean, robust framework. It is built in C# and is entirely free for use, even in commercial products. In a refreshing departure from the restrictive licensing models common in the software sector, Brutal imposes no royalties on its users. The only requirement for those who adopt it is to include a simple Brutal copyright notice within their game’s credits. Despite its relatively recent public unveiling, the framework has already been battle-tested across six distinct projects spanning three different studios. These include RocketWerkz’s own title Kitten Space Adventure and the underlying Waylith engine, which powers Ludeon Studios’ critically acclaimed Rimworld. Notably, Felipe Falanghe, the creator of the iconic Kerbal Space Program, is also leveraging Brutal for his ongoing projects.
The technical architecture of Brutal is built around a custom interoperability layer that provides C# with direct access to native APIs and libraries. Hall, who rose to global prominence as the creator of the seminal survival game DayZ, emphasizes that the framework was forged with an "obsessive focus" on efficiency. By minimizing memory allocations and stripping away unnecessary overhead, the developers have prioritized doing a small set of low-level tasks with maximum performance. This allows developers to use Brutal as a foundational layer to build their own bespoke engines—as Ludeon Studios has demonstrated—or to develop smaller, focused titles directly within the framework.
The impetus behind Brutal is rooted in a growing dissatisfaction with the current state of the game engine market. Hall has been vocal about his belief that industry giants, specifically Unity and Epic Games’ Unreal Engine, have "consistently" failed to be held accountable to the creators who depend on them. According to Hall, the reliance on these closed-source platforms creates a precarious environment for developers, one that he believes will only deteriorate as the industry evolves.
"I think this problem could get much worse as agentic workflows begin undermining the competitive advantages that have protected established software companies," Hall noted in a detailed breakdown on Reddit. "My concern is that as those advantages erode, the companies involved will increasingly look to extract more revenue from developers who feel they cannot switch. Whether through royalties, subscriptions, or more restrictive licensing."
Hall’s critique is particularly sharp regarding the lack of agency that developers possess when their entire workflow is tethered to a proprietary engine. He points to the recent controversies surrounding Unity’s licensing changes, which caused widespread panic among developers who felt their livelihoods were at risk due to sudden shifts in corporate policy. Furthermore, Hall addresses the leadership at Epic Games, specifically CEO Tim Sweeney. While acknowledging Sweeney’s formidable reputation as a programmer, Hall suggests that the company has become distracted by the pursuit of trends such as the "metaverse" and aggressive AI integration. He argues that this focus has come at the expense of addressing the practical, daily struggles of developers, who are often forced to grapple with performance issues, instability, and the long-term consequences of decisions made by centralized engine vendors.
The fundamental issue, as Hall describes it, is the industry’s gradual acceptance of dependence as an inevitable state. "Imagine your ability to work on your own game depending on a decision made by a company you have absolutely no control over," he writes. For many small-to-medium studios, the threat of a change in licensing terms or a shift in engine support can feel like an existential risk. While Hall is pragmatic—admitting that Brutal is not intended to replace the comprehensive ecosystems provided by Unity or Unreal, which remain the correct choice for many projects—he believes the industry has reached a tipping point.
The introduction of Brutal is intended to serve as a proof-of-concept for a different way of working. By keeping the tools public and the source code accessible, Hall hopes to provide a "lifeboat" for developers who find themselves constrained by corporate policy. He views the project as a small, deliberate step toward rebalancing the power structure of game development. The goal is to ensure that if a creator builds a system on top of a framework, they are not merely renting access to their own work, but are instead in control of the foundational architecture.
Hall predicts that the industry is on the cusp of seeing a proliferation of similar frameworks. He suggests that the cost of developing alternatives to the monolithic engines of today is set to plummet, driven by improvements in software development efficiency and the desire for more autonomy. "I think we’re going to see many more frameworks like Brutal emerge in this environment," Hall stated. "Not because everyone will abandon existing engines, but because the cost of making alternatives is going to fall dramatically."
The philosophy behind Brutal is rooted in the idea of perpetual ownership and exit options. For Hall, the true value of an open-source framework lies in the ability to "fork" the code. If a company that provides a development tool eventually stops acting in the best interests of its users, the users should possess the inherent right to take that technology and continue their work independently. This principle of self-reliance is central to the project’s mission.
While Brutal is unlikely to solve every challenge facing the modern game developer, it offers a tangible alternative for those looking to reclaim control over their technical stack. By fostering an ecosystem where the tools are open, the overhead is low, and the licensing is transparent, Hall and his collaborators are challenging the industry to reconsider whether the convenience of a "black box" engine is truly worth the potential loss of creative and economic independence. As more developers look for ways to insulate themselves from the whims of large corporations, projects like Brutal may well become the foundation for a new, more resilient era of game development. For Hall, the path forward is clear: if the industry is to remain sustainable for independent voices, the tools they use must be as free and as accountable as the games they seek to build.
