Good,but it does need a few changes....
I love these type of flash movies,my friends and I play halo/halo 2 CTF online.And your flash movie is no exception.But try to make some better animation,some more humor(I loved the rocket launcher part),some more action(not much of it),make the characters talk too(but still keep the subtitles),and make it longer.Do that,and I and many other people,will love your video.
