Our work explores the application of the Waterfall model in game development through a case study involving an inexperienced team developing a Space Invaders clone. While Agile methodologies are widely favored in modern game development for their flexibility, the structured, phase-based nature of Waterfall presents certain advantages for teams with limited experience in iterative processes. We investigate how clearly defined stages- requirement analysis, design, implementation, testing, and maintenance-provide direction, minimize scope creep, and can support systematic progress and project success despite the team’s inexperience. Key findings suggest that Waterfall was effective in maintaining project control, with clear documentation and milestone tracking helping reduce ambiguity. However, the model also posed challenges in managing late-stage design changes and balancing creativity within a rigid structure. The paper compares these findings with insights from the literature on Agile and hybrid methodologies, especially in the context of novice teams. The case study concludes that although Waterfall’s predictability can benefit inexperienced developers, its success relies heavily on disciplined planning, well-defined roles, and the ability to adapt within a structured framework.
