Hmm, the animation is decent, the concept is fairly original for a zombie flick, (Video game trailer) and the muzzle flares were inventive. But it's truly the camera movements that stand out. (0:35, for example. Which is impressive even though it's a bit choppy.) I like the use of bigger 'swinging' movements, and it's too bad the trailer drops all of those for still frames later on. It's also too bad that it switches aspect ratios later on destroying the immersion factor. There's a bit of light-flicker, and there's really only a minute of video, so whiles it's not without it's flaws, it's decent nonetheless.
