GANTZ

Two students are hit by a train and awaken in a mysterious apartment where they learn that they now belong to "Gantz" an enigmatic spherical entity. Gantz fits the two teens with black super powered suits and advanced weaponry before sending them on many game-like missions where they get points for killing aliens. 100 points will allow them to leave or send someone else back to life. If they fail they can perish forever. (Madman Entertainment)
