In the future, the Earth became so over-populated that the governments started building space stations, to which people would be later transferred. Those space stations were protected by giant robots powered by special crystals. Academy Z specialized in educating its students in everything concerning those robots. Two teams - Red and White - are competing to gather crystals for the robots, and learning to navigate them to become future protectors of humanity. Aya is a young girl who just joined the Red Team - first training in safe areas, but hoping to become a real robot pilot later.
The game plays mostly like a first-person dungeon crawler. The player navigates Aya's robot through pseudo-3D maze-like environments. Hostile robots appear randomly. The combat system is rather simple, with standard Japanese RPG-style options ("Attack", "Flee", "Use Item", etc.). Experience points are gained to level up and become stronger. There are also adventure elements in the game: at any time, pressing the Space key will bring a typical Japanese-style adventure interaction menu with options such as "Look", "Talk", etc. Movement outside of hostile areas is also done through menu commands.
