The player can steal, drive, and customize vehicles, and purchase weapons and clothing.
Saints Row IV shares most of its gameplay aspects with the previous installment, being primarily played as a third-person shooter in an open world map scattered with campaign quests, secondary objectives, and various collectibles. Objectives are often based around hacking the simulation in order to work towards escaping it. The simulation has Steelport constantly cloaked in the darkness of night, with largely computer-themed twists on classic Saints Row elements. The game's plot sees invading aliens place the player into a computer-simulated version of Steelport early on, and the bulk of the game takes place within this simulation.
