The trading card game inspired a television anime in 2014.
The card game also inspired a PlayStation 3 game, a PC browser game, and two manga series in Shueisha’s V Jump magazine.
The original Z/X Zillions of enemy X trading card game advertises itself as the “first free” trading card game system because card shops and events hold meets that offer free decks.
The official website for the Z/X Code OverBoost smartphone game announced on Wednesday that the game will end service on July 20.
