@@randymarsh9488 besides the fact that MWIII should’ve been free DLC for MWII, having a battle pass in a $70 game is ridiculous. Battle pass system is for free2play games not fully priced triple a titles. Its robbery
For some reason for me it only changes the menu music, all of the music during matches is still the default one I've looked up how to fix it but all I've seen is people asking how to fix it without getting any answers
I believe that if you go the Customize tab, and then Music, you’ll find the audio pack, then just go the the bundle to buy it in the store. Let me know if that helped. That way, also, you turn it on or switch to the MWIII OST.
