For every country, there is a black ball named Gantz, it transport the recently dead people into a small room on a ‘mission day’ (any normal person can enter the room after dying, such as getting run over by a vehicle, murdered, accident, disease, old age, even cancer will be cured once in the room) which all the participants will be forced to hunt and kill aliens, each mission usually much stronger than the last. They are given weapons of new technology and a suit which enhances their physical strength, endurance, power, agility and protect from harm against most blunt attacks but most new players are not aware of this, as rules or any knowledge will not be given out and must learn through trail and error which is often deadly or through a veteran that is willing to explain the situation.
If the player survives the mission, they will be able to be set free for a certain amount of time before the next calling of a mission. The players do not know that each person has a bomb implanted inside their brain after the teleportation to the room with the black ball, the bomb will be trigger whenever on a mission the player crosses over past the set location of the boundaries , which is similar to the Japanese film ‘ Battle Royale’ or tell anyone who is not involved with Gantz, this is simply to hide the presents and keep Gantz a secret.
During a mission, they are send outside of the room with the black ball while during these missions they might encounter normal humans not involved with the game, those people can not see or hear them until the mission is over and are still alive after the mission.
Any fatal injury, loss of blood or limbs will return after the transportation back to the room (arm/ legs cut off) if still alive and breathing which they will be given ‘points’ to reach 100 points then to use, the amount of points given depend on how many and how strong the aliens the player as killed, once 100 points have been achieved a list of 3 option will be given.
Further note:
As we all know, humans have hearing range is between 20Hz and 20,000Hz
human eye can see respond to wavelength in air from 380 to 750 nm
The Gantz technology known as the ‘controller’ is a radar device used for searching aliens which can also be used to turn humans invisible to the naked eye by changing frequencies.
aliens live in ranges that is invisible to normal human senses and only when Gantz teleports a person to a mission, Gantz changes the frequency along with them.
The veteran Nishi claims that once the catastrophe time countdown reaches zero, there will be destruction that ’Power’ and ’Authority’ will be gone and chaos will start, no rules, no law and order. Nuclear war will start, as Humans not involved with Gantz have seen the deadly Aliens and that Aliens have and will become visible to the human eye on the day of Catastrophe (Apocalypse/ End of the world/ Doomsday); Humans will use Nuclear weapons to fight against the Alien Invasion rather than the Gantz Technology.
Vampires seem to be ally with the Allies, or at least in good terms with them.
The Vampires call the Gantz members ‘Hunters’ and that the Vampires are helping the aliens to get rid of the worlds secret defence (Gantz)
