Wowhead just datamined a whole bunch of in-game music and sounds from the Warlords of Draenor alpha. Near the bottom of the massive post is a full listing of the ranged weapons sounds, which includes bows, crossbows, and guns. These sounds were split up into individual “reload” and “shoot” variations so I edited all of the variations together to give you a better idea of what it will sound like. Enjoy!
I think the sounds are a big improvement, especially the gun sounds. What do you think? Check the Wowhead post to see all the new audio.
