Virtual reality (VR) has become one of the most important technological tools for educational innovation in recent years. This paper presents a modularly developed VR-based serious game: a survival simulator and its areas of application. The application exploits the possibilities of immersive VR in learning environments and problem-solving situations, for example, it provides an opportunity to acquire practical skills and competencies in safe and realistic situations; and it can improve motivation and increase creativity. The technological novelty of the application lies in its modularity, and thus its easy customizability. From an educational methodological point of view, its uniqueness lies in the fact that the content and the simulation scenario can be customized based on professional consultation before the development of the process. The application develops resource use, object recognition, spatial orientation and navigation skills through a survival simulation in nature. It can also be used well in behavioral assessment, as well as in the development of decision-making and problem-solving skills in various competencies. This article provides suggestions for the application and further development possibilities of the application.
