Earth is too small for me

There used to be a man called the strongest. He defeated all the villains with one blow. His descendants were naturally the strongest. Then 2000 years passed. His descendant had been given his own star by the Earth Federation Government... A 3D third person shooter. A game for a single player only. It is a game in which the main character, "Strongest Legend, " is manipulated to defeat the enemy and head for the destination of the dungeon.
