Not bad but room for improvement
It's show's that you put time into your flash. And while there is room for improvement it's not bad for your first flash submitted. I liked the different style of animation. Though I think you should work on your character animation, and design. To give them a more realistic look (example - the dead guard lying on the ground could look better). Also your frame rate could use some speeding up. Example being the helecopter piloet talking, or when Knox is talking to the cheif the movement (blinking, talking) is slow. Your sound FX were good. But you should up the vocal level's being as in some part's you can't really hear the people talking over the background music. For the background music it was well displayed, but repetitive. A way to find some good background music is in the Music Portal here on Newground's they have just about every type of music you could think of. Overall for a first submission this is a decent flash. I look forward to seeing the next episode in the series (if you have chosen to make it) and the improvement's to come.
