Replaces Into Nirvana of TEKKEN 5. Theme probably has other kind of names but that was the first one that popped up.
Place in your "TEKKEN 8\Polaris\Content\Paks\Mods" if that doesnt work place in the ~mods folder. If you have a LogicMods folder instead and the mod doesnt work add _P to the end of the .PAK file.
