LDG-Gaming

This is a good deal, but this time it's about the CryEngine and not a game. They've made a bundle with assets (textures, animations, characters/animals...) in Pay What You Want, some of you may be interested:

I'm not an expert, but can this be bought and it's assets be implemented into UT2004? If so I don't mind buying and gifting to the server.
