This document summarizes the key aspects of Captain Strike, a mobile multiplayer online battle arena (MOBA) game developed by JOY Entertainment. It discusses the game engine, back-end systems, analytics/admin tools, and monetization approaches used. While developing the game internally provided benefits like flexibility and cost savings, it also required significant resources and led to bugs. The summary identifies areas for improvement such as using commercial game engines and analytics tools to reduce workload and adopt better monetization strategies used by other developers.
