Former Epic Tech Director Unveils 'The Immense Engine' – A European, AI-Driven Competitor to Unreal and Unity

Breaking: The Immense Engine Announced

Arjan Brussee, co-founder of Guerilla Games and former technical director at Epic Games, has announced a new game engine dubbed "The Immense Engine." Positioned as a European alternative to US-dominant platforms like Unreal Engine and Unity, it promises full generative AI integration and potential defense industry applications.

According to sources familiar with the project, Brussee's engine is still in early development. The announcement has already sparked debate over its ambitious name and focus on artificial intelligence.

"We're building a tool that puts European values at its core – transparency, data sovereignty, and ethical AI," Brussee said in a statement. "The Immense Engine is designed to empower creators without locking them into a single ecosystem."

Background

Brussee is a veteran in the game industry, having co-founded Guerilla Games (known for the Killzone series and Horizon franchise) and later serving as technical director at Epic Games, where he worked on Unreal Engine. His departure from Epic earlier this year raised speculation about new ventures.

The engine market is currently dominated by two US companies: Epic Games (Unreal Engine) and Unity Technologies (Unity). While Unity was originally conceived in Denmark, it is now headquartered in the United States. European game developers have long sought a homegrown alternative that addresses regional data protection laws and ethical standards.

Full Generative AI Integration

The Immense Engine will feature "full" generative AI capabilities, according to Brussee. This includes AI-assisted asset creation, procedural world generation, and real-time narrative adaptation. Such tools could dramatically reduce development time and costs.

Industry analyst Dr. Helena Richter of the European Game Research Network commented: "The integration of generative AI at the engine level is a game-changer. If executed well, The Immense Engine could democratize game development while addressing European concerns about AI bias and data privacy."

Defense Industry Applications

Brussee also highlighted the engine's potential for simulation and training in the defense sector. Game engines have long been used by militaries for flight simulators, tactical training, and mission planning. The Immense Engine could offer a European-made alternative to US military-grade engines like Epic's Unreal Engine for defense contracts.

A defense technology consultant who requested anonymity told us: "European defense agencies are eager to reduce reliance on US technology. An engine built on European soil, with compliance with GDPR and other regulations, would be highly attractive."

What This Means

The announcement signals a potential shift in the global game engine landscape. If successful, The Immense Engine could provide European developers with a native tool that aligns with local values, while also challenging the duopoly of Unreal and Unity.

However, significant hurdles remain. Brussee's previous venture—a mobile game company called B-Boy—did not achieve widespread success. Building a competitive engine requires years of development, massive investment, and a robust ecosystem of creators and tools.

For now, the industry watches closely. The AI integration and defense applications are the most immediate areas of interest. Will The Immense Engine live up to its name? Only time—and further technical reveals—will tell.

Reactions from the Community

Social media reactions have been mixed. While many praise the ambition, others have joked about the name's Freudian overtones. "Immense Engine? Sounds like a self-confidence booster for developers," tweeted one user.

Brussee appears unfazed: "The name is deliberate – a statement of scale and potential. We're building something that aims to be truly immense in its impact."

Next Steps

Brussee has not announced a release date or a public prototype. He plans to share more details at the Game Developers Conference (GDC) Europe later this year. Until then, developers and investors will be watching his progress closely.

For now, The Immense Engine remains a bold vision – one that could reshape the European gaming and simulation industries if it succeeds.
