i've reached the vishnans blowing the almighty **** out of the 3 shivan destroyers (which would make a kickass cutscene i think), and so far

the voice acting is the best i've heard in any campaign save retail,
though i haven't actually played very many with voice acting. agree with all who already stated the females are outstanding. taylor sounds sexy

(sorry if that comes out creepy

). the radio filtering you asked about, i'd call perfect. the vishnans sound awsome, though i would have had trouble understanding them without the text. (only heard them once so far). visuals are nothing short of awe inspiring. did the pulse cannon effect change, or am i just not remembering the original very well?
but now let me nitpick. as with someone else who already posted (i forget who), there were one or two weak points with taylor i noticed in the early missions. i'm not really sure how to describe it... overacted maybe? and on that note, i found MUCH of samuel overly dramatic, particularly in the briefs/debriefs. this is space combat with aliens intent on wiping out the human race, not shakespearan theater.

the nebula beyond the portal is well done, but way too bright in my opinion. it seems like half the possible orientations have you blinded by sun glare, and when you're not, it is still rather harshly bright. i found it difficult to use the hud in these missions.
the cutscenes are even better than before, but i have one bug to report and one suggestion. tagged on the off chance someone reading this hasn't ever played BP.
the lucifer's model was messed up in the escape pod's cutscene. i have a screenshot, if someone can remind me where they save

also for that cutscene, i was under the impression we were watching the battle from the fleeing pod's perspective. this being the case, there are 2 problems with this cutscene - 1) (minor) it passes RIGHT next to the lucifer. i would imagine an escape pod wouldn't want to pass that close. 2) the camera pans to the other side of the battle. this couldn't have been recorded from the escape pod, unless it somehow got to traveling many hundred m/s. i really liked the panning effect, but it doesn't fit in with the EP aspect.
