Deep Silver and Volition today release Saints Row IV across North and Latin America and on August 23, 2013 in the rest of the world.

Defend the freedom of the world as the President and assemble your own cabinet comprised of your trusted Third Street Saints.
Enter the virtual simulation of Steelport and use your newly gained superpowers to oppose the alien invasion, kick alien posteriors and stand face to face with the Supreme Overlord of the Zin Empire, @EmperorZinyak.
Only in Saints Row IV!

In Saints Row IV, the head honcho of the Saints has been elected to the Presidency of the United States. But the Saints are just getting started. Now the larger-than-life insanity of the Saints series gets a new twist with a catastrophic alien invasion, and the aliens have transported the Saints to a bizarro-Steelport simulation. Wield gargantuan superpowers and fight to free humanity from alien granddaddy Zinyak’s mental grasp. Escape the simulation that’s trapped the Saints crew, or die trying. Saints Row IV lets players delve into an arsenal of alien weaponry and technology that will turn each Saint into an ultimate entity of destruction. Utilize out-of-this-world superpowers to fight all the way to the top. With intensified action and enhanced customization, players can use their newfound superpowers and leap over buildings, outrun the fastest sports cars, or send enemies flying with telekinesis in the greatest, most insane installment of Saints Row yet.
