here is one of the files to the costume and some pixel animation changes mod. This can only be applied on a normal version of the game by replacing the files
Some visual MODs, didn't bother with the other one but the one I tried changes the title screen animations, standing pictures, some X-ray scenes and some of the pixel animations. It's a WIP so the guy doing the MOD will probably keep adding/changing stuff.
Here, backup your WWW folder then replace the files as asked.
