Digital forensics education faces significant challenges, characterized by steep learning curves, resource-intensive laboratory setups, and a lack of student engagement with traditional text-based exercises. This thesis presents the design, development, and evaluation of CyberForensics Arena, a web-based serious game designed to bridge the gap between theoretical knowledge and practical investigative skills. The platform immerses learners in a realistic 3D forensic laboratory, where they assume the role of an investigator solving complex cybercrimes. Unlike traditional training environments that rely on static quizzes or abstract command-line interfaces, CyberForensics Arena integrates an interactive 3D environment with a fully simulated Linux terminal. This hybrid approach enables students to perform authentic forensic procedures, such as disk imaging, memory analysis, and network packet inspection, within a cohesive narrative context.
