Details: Originally released in 2015. This is a stand alone game independent from Saints Row IV. I purchased the game for PC through Steam for $3.74. I spent about four hours playing the game.
Gat Out of Hell is standalone downloadable content for Saints Row IV, similar to how Freedom Cry was standalone DLC for Assassin’s Creed IV. That means you don’t need Saints Row IV to play this game, but it continues the story and looks the same technically.
