Saints Row 3 Cheats For Xbox 360, PS3, Nintendo Switch and PC
Cheats, Codes, and Secrets - Saints Row 3 Wiki Guide - IGN
Saints Row is a ludicrous open world action series about doing ludicrous things with ludicrous powers and, also, dildo bats. Abilities you unlock throughout Saints Row the Third let you sprint forever, reload guns instantly, and walk away from explosions without a scratch, but it doesn't have the fourth game's crazy super powers, which give you telekinesis and let you super jump across the world. With these Saints Row 3 cheats, however, you can still play god. The Saints Row the Third cheats below let you spawn in weapons and vehicles, and also let you manipulate some of the game's major systems. You can change the weather, earn instant gang notoriety, or turn all the pedestrians into zombies. As far as we know, these Saints Row 3 cheats will all work in Saints Row the Third Remastered the same as they do in the original game.
