PR sound: Sounds fine when you're firing it, but it should be the original legit sounds when someone else is firing it. I didn't really hear it that well in this video.
As far as the different xeno types: It should add more strategy to the multiplayer. I agree, being a Marine I won't have a problem mowing down / dying by the same xenos. If I were inclined to be a xeno though, options are nice to plan different strategies. It will keep multiplayer interesting, it's going to (HAS) come at the cost of p*ssing off a lot of fans though.
Really until we play it and feel how it works, we're speculating that change is baaaaad. And yup, it definitely could be. We'll see... If in the end it keeps me, and lots of others on the servers, I'm all for it.
