Today serious games, i.e. software applications developed with game technology and design principles for a primary purpose other than pure entertainment, include games used for educational, persuasive, pedagogical, political, or health and training purposes. This paper describes the work-in-progress development of an interactive 3D training application generated using components of the Unreal game engine that facilitate the learning of various fundamental coaching methods via the interactive completion of a variety of interrelated tasks. Apart from highlighting the contribution and innovation of this approach, a synopsis of the coach training content of the serious game and its purpose is also presented here, as well as an architecture overview of the implementation of the prototype application. Finally, future directions for the completion and evaluation of this serious game are also discussed.
