Nice animated.
Nice animated, I can give you that. The story lined... well I can't come up with a single zombie movie were there is a really good one, so I guess that's okay.
It's just... that I hate most of the sounds used. "Hello, is anyone there?" drove me crazy with all the loops. And of all the sounds in the world, you decided to use Hydralisk from StarCraft, and their flying kamikaze bombers' diyng sound. Didn't fit, is my opinion.
