Bethesda was looking to bring the world of modding to Fallout 4 and Skyrim to PlayStation 4 like they did with the Xbox One versions of the games. However, the developer has confirmed that mods will not be coming to PlayStation 4 and the blame has been placed squarely at the feet of Sony.
The announcement on the Bethesda website mentions that Sony would not approve mods in a way which worked
After months of discussion with Sony, we regret to say that while we have long been ready to offer mod support on PlayStation 4, Sony has informed us they will not approve user mods the way they should work: where users can do anything they want for either Fallout 4 or Skyrim Special Edition.
Like you, we are disappointed by Sony’s decision given the considerable time and effort we have put into this project, and the amount of time our fans have waited for mod support to arrive. We consider this an important initiative and we hope to find other ways user mods can be available for our PlayStation audience. However, until Sony will allow us to offer proper mod support for PS4, that content for Fallout 4 and Skyrim on PlayStation 4 will not be available.
We will provide an update if and when this situation changes.
Bethesda has previously shown a player demand for mods after announcing that mods received 50 times more traffic on Xbox One than on PC. Of course, PC players don’t have to go through Bethesda to get mods like Xbox One owners do, but it is still significant amounts of traffic.
Fallout 4 is available for PC, PlayStation 4 and Xbox One. Skyrim is available for PC, PlayStation 3 and Xbox 360. Skyrim Special Edition is available for PlayStation 4 and Xbox One starting on the 28th October 2016.
