Very well done
Great work. The animation was very smooth, which is essential in this type of animations. Kinda missed weapons, but eh, possibly either you just didn't want them or it's more difficult to animate. *Shrugs* I'm no flash artist, so I wouldn't know. Also, could have been longer, but that's just me begging for more. Honestly, do a sequel.
Anyway, I also loved the ending. Very climactic, with the decapitation and all.
All in all, very good work. And I must say, this was almost as good as the SHOCK series.
