- Guerrilla co-founder Arjan Brussee is developing an engine with full AI integration to rival UE5.
- The former Epic dev thinks new software built on AI-based principles could do the work of 10 people.
- Titled The Immense Engine, this software will be fully hosted in Europe.
Unreal Engine 5 has developed an unspoken dominance in the gaming world since its inception. Besides studios that employ an in-house engine, most developers utilise the Epic software. However, titles using Unreal Engine 5 have notoriously suffered from performance issues, with the Metal Gear Solid 3 remake being a recent example of this.
Developers have started to trim the engine’s key features to achieve better results with Phantom Blade Zero and Arc Raiders, implementing this method. However, studios could obtain a formidable alternative to Unreal Engine 5 if Guerrilla co-founder Arjan Brussee succeeds in his efforts.
Why it matters: Unreal Engine 5 is in no way horrible, but having options is never bad, and if the software gets some competition, Epic might work harder on its next iteration.
In an interview with De Technology, former Epic programmer Arjan Brussee revealed that he is building a new game engine called The Immense Engine with a Dutch startup that will offer developers a European alternative to American and Chinese software.
The rise of AI means that we need to approach the development of this kind of crucial software differently. If you are smart and know how to put a good framework of AI agents to work, you can do the work of ten or fifteen people.
The Guerrilla co-founder explained that he sees this new engine as an opportunity to build something with the full integration of AI. Unlike Unreal, which is made by and for people who are used to manual work, The Immense Engine will be built on entirely new construction principles that utilise a framework of AI agents.
AI agents like Claude and ChatGPT will be present as modules inside this new software, and new features for any LLM can be easily integrated into the engine. Brussee is approaching the development of The Immense Engine differently due to AI’s meteoric rise, and the Dutch industry veteran thinks developers can do the work of 10 people by utilising AI agents.

Moreover, Arjan Brussee also emphasized the importance of this software being European, as the region doesn’t have an engine natively built and hosted by Europeans. Therefore, if or when he succeeds in building it, The Immense Engine could also be utilised for Defence and Logistics.
