So far no Anaconda sound, but the sound is definitely NOT the same as anywhere else I have landed. Lots of background static now. Maybe it's evolving? So many ships around I had to go open to get a quiet sample.
I wish I'd recorded the sound when I was landed 850LY from NGC6357, but I assure you, it was exactly the sound in the videos. To the extent that, when I played the videos while still in game, I couldn't really tell when the vid stopped and the in game sound took over. I'm sure it's because I was landed and pointed at the LMC. In the vid, it's impossible to tell what the ship is pointing towards because of the dust / mist unfortunately.
