ガニメデ戦記Zero+ (The War Chronicles of Ganymede Zero+) is a two to four player card game from Japan in which Mechs are enhanced with transparent cards. In 209X, Nigaleos, who was contracted for development by the Veil Army, was developing two types of Mechs, one specialized in attack and one specialized in defense. The airframe was built at both the research base and the production base. The introduction of this 'Mech to the front line should have brought the battle on Ganymede to an end quickly. MEC engineers believed so and continued development. But Nigaleos executives had a different idea. Ganymede Senki Zero+ contains both ガニメデ戦記Zero and ガニメデ戦記Zero 2 and play with up to 4 people.
