Importing (very) old assets into UE4

Hi, I’m working on remaking a very old title from 2003 that was made in UE2 and the Unreal Development Kit (UDK), even though I can extract the assets from the original title, I don’t exactly want to rewrite the entire game from scratch.
This is strictly a passion project as I have replayed this game too many times when I was younger.
The game in question is Devastation: Resistance Breeds Revolution.

The maps are in a .dvs file format, meshes are .usx packages, and textures are .utx packages.
I cannot, for the life of me, find a way to export those files into something that’s at least somewhat readable by UE4.

The game comes with its own dev tools that allow you to open any asset from the game, include its own maps, textures etc.


I am not sure if there are any tools available for this. If there aren’t, at least I won’t have to spend hours looking for ways to do this.

Thank you in advance.
