i don't know it. I'm trying to do that on my map too, but i have a problem. I can tell you something about that, but for a problem i don't really know why it doesn't work.  Make a new file .csv     you can rename it as you want. go in raw/soundaliases and look for the file: dlc_share.csv. Open it and copy the line up and a write down that should start with name mx_game_over,.......   I hope you know how the file soundalias works. (mx_game_over, name folder/name file song.wav   into your soundalias, make sure the line up is up and the other one leave some space and put it down. Save the file.csv and close it. Put it in raw/soundaliases.  Then you'll want to put of course the song, then go in root/sound_asset/Raw/sound and create a new folder with the same name you put in your soundalias and put it inside the song you want that will be played when you die, remember to rename it whatever you want but with the same name in the soundalias. Then open the Launcher, go to build the mod, thick build mod .ff fast files and build sound; compile and you should give an error, it doesn't matter, just go in root/raw/sound and you should find the folder you created and the song at the inside of it: namesong.wav; this means the song has been converted successfully. Copy the song converted go into mods folder, your mapname folder create a folder sound, create the folder with the same name like you did and put inside the song converted. After this go into your mods folder/MAPNAME folder/clientscripts folder and open your MAPNAME_amb.csc file. look for mx_game_over and edit that to the name in the soundalias file you created i put for example mx_game_over_custom. In fact back to your soundalias file created and edit the name inside the soundalias file: mx_game_over to mx_game_over_custom but you can edit that to whatever you want just make sure that its and the name in the mapname_amb.csc have the same write. Then i don't know if you must do that, but go into the file zombiemode.gsc, you should find it in root/raw/maps oh well, if u didn't put it into your mapname folder/ maps folder, just do it. Open it and look for mx_game_over and always edit it to mx_game_over_custom for example. After this open your Launcher again, thick everything, like the song put in mapname folder/ sound.......   So, thick everything and write in mod.csv which would be that thing under with all writes and write at the bottom: sound,your soundalias name,,all_sp. Then thick build mod.ff Fastfile and Build mod IWD as you often do. So, build your mod. I don't know why, but when i die, it quite works, i mean: when i die, my custom music doesn't begin, but it just stop the game over music standard, so when i die, it's completely silent I don't understand why, but that i stopped the music standard, it's already a big thing. I hope you'll read it and helped you with this. Bye
