The user General_Han_Solo has made some fantastic upgrades to my original contribution. Anyone is welcome to port, edit or use these textures for that if they want, of course. As for Rebel Strike, I don't remember if that uses the same assets, but I don't have the game nor the specs to run it at the moment, so maybe in the future I'll do a retexture for that. Updates for this will be slow, since I have the Xenoblade pack as a bigger priority. As the time of writing this, I believe this is the most recent and efficient Z Freeze build.
If you need help setting up or playing the game, head here. I'm not good at drawing realistic stuff, so I focused on the hud, which was my goal to begin with. Also note that the 'Space' folder is basically just optional, since those are edited images from around the web or the game itself (this game has a surprising amount of high quality textures). Feel free to delete the folder you're not going to use. The download includes 'Fast' and 'Safe' folders, so people with lower specs can still use them.
