I was playing the preview build and noticed that the Sonic Railgun has no firing noises. I also agree that the shotgun fires a bit too slowly, making its fire rate almost close to the super shotgun's. I'm not sure what the difference between the classes at the moment is either, other than the pistol/slot 4 rifle. And is there a leveling system? I saw it in the older video, but not while playing.
