Oh and I like the story developement you had at the start of the vid, everyone arming and then running at each other to set the stage. but after that it was just endless battle you need some sort of ending or progression of battle even though it's non linear. have everyone of one team die or something.

not bad, you had to many go-to-black's though, you might be able to get away with 2 of those but maybe use 1 of them for a slo mo explosion or a super montage series of like 40 clips in 8 seconds. that would look good.
