Drew Carter

Drew was drafted for WW4 as a tactician and rifleman.
When it was finally over, went on his way home to finally see his 4-year old boy Andy, only to have the helicopter carrying him and a lot of his friends attacked, sending them plummeting to their doom.

Drew was the only survivor, finding himself in a city forgotten, left for dead during the war.
This city is called BattleTown by the residents, who are under a regime called the Red Crown, who force poor survivors to participate in gladiatorial events for food and supplies using their superior weaponry.

Drew thought that he would spend the rest of his life fighting in an arena, but a small group rescued him and brought him to a safe haven, where they plot to dismantle this twisted game.
