This paper presents a novel approach in industrial maintenance training with the development of an interactive game using the Unity3D game engine, aimed at simulating the Compressor Air System maintenance process. Incorporating Extended Reality technologies, this educational tool strives to improve the practical skills and safety awareness of maintenance personnel by simulating real-life scenarios in an engaging environment. This facilitates a deeper understanding of technical challenges and maintenance operations. The study highlights the significance of game-based learning in technical education and virtual simulations’ role in enhancing the learning experience. Utilizing Unity3D platform's robust graphical and physics engines, the game constructs an immersive 3D industrial environment with interactive modules designed to assist technicians in overcoming common challenges, thereby sharpening critical skills such as decision-making, problem-solving, and analytical thinking. With realistic controls, the game guides participants through the compressor maintenance process, dynamically responding to user interactions. This method not only allows learners to refine their technical skills but also to perform maintenance tasks with an emphasis on safety. Performance evaluation is based on adherence to safety standards and technical accuracy, underscoring impact of game-based learning and virtual simulations in enriching technical education.
