Eh, for your first flash
I'd have to say.. im impressed, your style is good, but theres a couple things you need to work out.
Graphics - I gave a 4, becuse theres not a whole lot of animation, but some good drawings
Style - fucking 10 all the way, MGS vs CS? brilliant.
Sound - Bleh, i dont like the offsprings to much, so i gave it a 3
Voilence - 6, becuse they got exploding heads, which is one thing you need to work on. :)
-Mystic- 3/5
