The goal of this final thesis is to present the technical aspects of video game development within the Unreal Engine environment, with an emphasis on the action roguelike genre. This type of game combines fast-paced action and randomly generated challenges, giving players a dynamic experience full of unpredictable elements. Throughout game development, the developer uses tools such as Blueprints (visual scripting) and the C++ programming language, which are key to creating complex systems within the Unreal Engine. Making these kinds of games requires knowledge of various aspects of development, including level design, working with 3D models, animations, and programming AI enemies and their behaviors. During the development process, special attention was paid to balancing the gameplay, ensuring that each pass through the game offers a unique experience. This is achieved by random generation of levels, and changes in the appearance and abilities of enemies, which keeps the game fresh even after multiple playthroughs.
