In game music
 

In my short time testing the beta, while in-game mechanics are paramount, there is 1 thing that stand out on a nostalgic level. Music.

Velkators labyrinth had the zone theme music playing in a loop, which really added to the nostalgic factor and the Kael arena had combat theme 2 playing in a loop. I'm not sure if this is client side or triggered as an in game sound, however it's currently missing from the game.

Any thoughts?

Can't speak for Kael Drakkel but Velk's Lab was playing the music just fine for me. Check in the options (alt-o) that music is turned on ;)
