Catastrophe Now (Japanese: カタストロフ ナウ)[1] is a track used in Wild Arms 4 which plays during the very first battles of the game at Ciel Shelter and during a cutscene at Garra de Leon between Kresnik Ahtreide and Third Class Pilot Tony just before battle. The song also plays during the first battle with Augst Henriksen after he has turned himself into a Wild ARM.
