This option appeared halfway through the series.Īfter a mission has been completed, points are tallied up, the participants are allowed to leave and do as they see fit until their next mission, with the exception of talking about Gantz which would lead to their heads exploding. Option 3: The participant can revive someone who has died during a mission from Gantz' memory.Option 2: The participant obtains a unique and extremely-powerful weapon.As a price, their memories of Gantz and the missions will be erased.

Option 1: The participant can return to their normal life, never having to be summoned by Gantz again.Once a participant has scored 100 points, a '100 point menu' will appear.

Gantz transports them to the area of the mission, and they cannot leave or return until all the enemies have been killed, or the time limit has run out. During the mission, normal people cannot see the players or the aliens. Except for a single mission, all the targets are aliens living on Earth, which take on a wide variety of forms. A picture and brief information is shown of some of the Gantz' targets Gantz orders them to go and kill them. When the Gantz sphere opens, green text appears on its surface, informing those present that their 'lives have ended and now belong to him'.
