I know the normal version was already made, but it conflicted with a mod using the same song. Here's my version :)

Ada Mercenaries (Normal) Replaces Ruin 65th 1st - TEKKEN 7

Ada Mercenaries (Mayhem) Replaces Lights - TEKKEN 4

Place in your "TEKKEN 8\Polaris\Content\Paks\Mods". "_P" should already be applied to the .PAK file. If that doesnt work, place in the '\~mods' or '\LogicMods' folder if you have a LogicMods folder instead.
