Definately a big improvement.
Wowwie, that was a great improvement on the last installment's everything, cept maybe the music.
The Goods:
*Artwork was definately better, although the Zerg still could use a little more of a organic feel, (i.e. Random organs just outside their "skeleton" and things like that)
*Styles still very original, you can't find a lot of people who can do 3D animation.
*Faces had a little bit of improvement
*Overall just great
The Bads:
*The voice acting wasn't at it's best, The ghost's voice was a little bit too muffled at points, and sometimes they should have staggering tones, like with more umph when they're in danger and things like that
*More gore...but it didn't look the realist, it could use a bit of touching up.
*Play buttons, scene selection, all that stuff is present.
Great job, i look forward to all your future stuff.
