Can you put mods on GTA 5 on ps4?
Apparently, yes. Kind of.
Well, technically, you can actually get GTA V mods on PS4, but not officially. Rockstar Games hasn’t endorsed the use of mods, nor is it an intentional feature of the console version of the game. If you do want to install GTA V mods on your PS4, you’ll need to make use of an exploit within the PS4’s firmware, as well as go about not updating your system or the game. As a result, it’s far from a practical thing to do if you find yourself playing a lot of different games on your system.
