Guerilla Games’ Co-founder Developing 'European Alternative' to Unreal Engine

Guerrilla Games co-founder Arjan Brussee says he is building Immense Engine, a startup aimed at challenging Unreal Engine.

The Netherlands-based engine is designed as an AI-native rendering platform with modular agentic components.

It will use Europe-hosted cloud infrastructure, positioning it as a European alternative with stronger data-compliance appeal.

The project could make Europe a bigger player in game-engine software and test whether AI-first architecture improves development tools.
