While on Tarsis I get basically zero sound. I don't know if it was like this the entire weekend, but it sounds way way quieter than any other location. Even the UI sounds quieter there.
It's like a spooky ghost town where Zoe occasionally says something, but I can barely hear it.
Definitely not going for spooky ghost town lol. I'm pretty sure you'll be happy with the main game, we spent a lot of time polishing it up. If not, let us know!
