EDIT #2: Ok problem solved, think it was on my end. I rebooted, and it seems to be fully working.

All weapons/sounds seem to be working flawless.

Except the Bio Rifle, I don't hear a firing sound.
And the secondary globs don't have impact sounds.

(Except when you full charge it and the normal globs emit from the large one)
Still thats only the normal glob impact.

Anyone else having this problem?
Or can they confirm it for me?

Oops sorry can someone move this to Beta Demo Feedback section?
