Abstract: This research project presents the development of a video game entitled “Chyilax” – an innovative three-dimensional video game about a person’s struggle against mental breakdown while trying to alleviate its symptoms. The game was developed to be a medium that would raise awareness about the risks and conditions of mental health breakdown. The player can choose to take the role of either a college student or a working adult, both experience symptoms due to a tangled situation in their past. The player was tasked to help the protagonist to overcome the symptoms before it leads to a nervous breakdown. In order to help the protagonist, make up with the people who got involved in their past circumstances through puzzle-solving, role-playing, and problem-solving. Chyilax was developed using Unity as its game engine while 3D models were created using Autodesk Maya. The project was tested and evaluated via a virtual open house. The questionnaires were collated online using an online form that assesses the following as criteria for the game: effectiveness, visuals, mechanics, audio, and enjoyment while the website: functionality, usability, reliability, performance, and supportability as criteria. The game received an overall mean of 4.32 while the website received an overall mean of 4.35, both of which have a verbal interpretation of “Strongly Agree”, which interprets that the objectives were achieved and drawn impact to raise awareness on issues focusing on mental breakdown.
