This is the fourth game in the Saints Row series, which is a popular action video game series that was created by the Canadian developer Victor Games.

The story of Saints Row IV takes place in the United States, which is the last main entry in the series. The story of the game is based on the real-world events of September 11, 2001, the terrorist attacks in the United States, and the politics of the country.

The game's main characters are the same as those of the previous games: the character known as the Boss is the leader of a group of terrorists, and the other characters are members of the military and the police.

In Saints Row IV, the Boss is in the midst of a crisis, which leads to the destruction of the world and the death of all the people.

The player is sent on a mission to prevent the terrorist leader from launching a nuclear attack and destroying the world.
