In 2048, the world is enthralled by the Immortal Grand Prix (IGPX), a high‑speed fighting race that outpaces any existing motorsport. The craze is so intense that a dedicated city was constructed around a massive track for the competitions. Each IGPX event pits two teams of three high‑tech humanoid mechs, IG machines, piloted by humans. The teams race at speeds exceeding 400 km/h, completing three laps of a 60 km course while battling each other for first place. Victory depends solely on machine performance, pilot skill, and teamwork.
