Typhoons remain among the most frequent and destructive natural disasters in the Philippines, underscoring the need for innovative preparedness strategies. This study presents Storm Shield: A 3D Strategic Co-op Game, a local multiplayer educational game that simulates the three phases of a typhoon–Before, During, and After–through mission-based levels emphasizing teamwork, planning, and decision-making. Players assume roles within a disaster response team and perform tasks such as preparing emergency kits, assisting civilians, and managing post-typhoon recovery. The game integrates action, strategy, and educational mechanics, supported by a Content Management System (CMS) website that reinforces learning. Effectiveness was evaluated through post-play surveys using Key Performance Indicators (KPI) covering functionality, entertainment, player experience, and educational value. Results show that Storm Shield engages players while improving knowledge of disaster preparedness and response. By merging learning with entertainment, the project demonstrates the potential of serious games to support disaster risk reduction and contributes to Sustainable Development Goal (SDG) 11 by promoting resilient communities through interactive education.
