It more sounds like the mod won’t work on the most current version of FO4, and because you can’t install older versions on Epic, it won’t work.
That’s a shockingly misleading title, even for vidya game “journalism”.
The headline is still true, I’m not sure what you think is misleading about it
Things can be true and also be misleading.
This is just shitty clickbait journalism. A more accurate headline “Anticipated Fallout 4 mod won’t work on current Fallout 4 versions” wouldn’t get the engagement and clicks that a more provocative bullshit title that indicates that Epic won’t let you play it does.
It more sounds like the mod won’t work on the most current version of FO4, and because you can’t install older versions on Epic, it won’t work.
So… What you’re saying is that it won’t work on Epic?
Just like other the fallout games on epic hopefully some nice person will create a patch for the exe.
