On March 17, 2005, Konami published a game for the PlayStation 2 based on the Gantz series, titled Gantz: The Game.

It features the characters and plot up to the Buddha Alien mission (though the vampires and the Shorty Aliens are present). The game may be classified as a third-person shooter, although it does have a few Role-playing game elements put together. The game also includes extras including Free Play mode, a Mini Mode, Magazine Browser mode, Gantz Rankings, a special preview movie and the scenario completion statistic.This game was never released outside of Japan.
