Gantz

A massive unknown flying craft lays waste to the planet's leading military superpower. Choas reigns. Gantz teams from all over the world gather in Italy only to be overwhelmed and ripped to pieces by endless foes. And just as their destruction seems assured, the Gantz warriors are transferred home and released without explanation from their duty by the Gantz orb. Is this a reward for courageous service or simply an admission that Armageddon is now inevitable?
