1.Go to your start menu and go to my computer.
2.Go into your hardrive and find your nexon folder.
3.Click on combatarms.
4.Click on the folder called game.
5.click on BGM.
6.Remove any peice of music you want and replace it with your own from itunes or from your music. Rename the new music the same as the old one.
7. All you need to do to change the music for when the map is loading is too delete the Map_Loading then put your peice of music there and rename yours to Map_Loading.
*Note* Everytime nexon has a patch or update they replace the folders so you have to replace them every patch. Hope i helped!
I will be posting some glitching soon in the glitching section of combatarms. I found some in grave digger so check em out.
