Saints Row IV is an action-adventure game released for Xbox 360, where players assume the role of the protagonist who is now the President of the United States. The game diverges from earlier installments by introducing an alien invasion led by the Zin. Much of the gameplay occurs within a simulated version of Steelport, where players must navigate challenges to rescue their allies and escape from the alien control.
Unlike the first three games in the franchise, Saints Row 4 does not center around the main character defeating three rival gangs in order to take over a city. The Saints have now become a household name, and their leader has become the president of the Unites States. The antagonists in Saints Row 4 are an invading alien race known as the Zin. Most of the game takes place within a computer simulation of the city of Steelport controlled by the Zin, where the protagonist is attempting to free himself and his companions.
