Paragon Asset Flipper Alert!

So many people claim to have their paragon remake released soon but i noticed that they all use paragon asset that are not on the market place… like sounds effect, map asset etc…
There is even one on Steam called Predecessor now in Alpha i noticed a lot of things that they use in their game that seems to come from the original .pak of paragon.
My question is ; is there any law behind all this or its literally free for all?

As long as they are using the assets in an Unreal Engine project then it’s allowed.

There are no laws because Epic wants people to use the assets. While I don’t want to do much with the models/sounds other than learn more about rigging, I personally think it’s fine to put them to some use.
