The final paper entitled making a 3D video game in Unreal Engine 5 includes the entire research, development and implementation of a 3D puzzle game using Unreal Engine 5. The paper describes in detail the goals and purpose of the game, a basic overview of the work structure and key aspects of the research and development process. The work is based on the application of object-oriented programming and visual programming through the blueprints, as well as the use of the C++ for the development of complex game components. Unreal Engine 5 was chosen as the main tool for game development due to its powerful and advanced functionality, cross-platform support and the ability to integrate with various tools. The paper describes in detail the creation of the project, the development of the environment and characters, the implementation of game mechanics and interactions, and the addition of new components and puzzles at higher levels of the game. Through the content of this final paper, a deeper insight into the process of 3D game development within Unreal Engine 5 will be gained, the key elements of object-oriented and visual programming and the application of the C++ language in game creation will be explored. Also, the importance of Unreal Engine 5 as a powerful and flexible tool for creating high-quality 3D games was highlighted.
