A standalone expansion to Saints Row IV, meaning players do not need a copy of Saints Row IV to play Gat out of Hell.

The player controls Johnny Gat or Kinzie Kensington in an open world environment. Gat out of Hell shares many gameplay aspects with the previous installments, being primarily played as a third-person shooter in an open world city scattered with quests, secondary objectives, and various collectibles. Unlike past Saints Row games, players cannot customize the playable characters; however, by importing a Saints Row IV save, players can import their custom Boss character to replace the default Boss.
