Wow...
This was...incredible...wow...
I'm stunned by the class of this flash movie...
The graphics where beautifull, although the animations could be smoother. Everything is in Halo (2) style, so no problems there either.
The music is taken directly from the series, so it matches perfectly. The sound effects do what they need to do, with some great voice acting (especially Master Chief & Cortana are perfect, and the aliens to of course ).
The blood effects could be better, but overall it didn't bother me that much.
And about the humor: amazing! For me this could get a perfect 10 out of 10, if it wasn't for the 4th mission (The Flood). Personally I don't like this one. Don't get me wrong: it's still a good flash movie, but the animations are not as good as in the other movies and the humor isn't as catchy...
Overall this animation rocks and if you guys take some time to make every mission as funny as (mainly) the first 3, this would be the best submission to newgrounds yet. Good luck...
