A lot of potential...
In response to your submission summary, I do know what WH40K is, and I STILL found this a bit odd. Not that it was incomprehensible or unfunny, rather that the presentation style was a bit iffy. I'd have advised a different soundtrack, as the blaring, rather imposing Beethoven's 5th remix didn't really complement the zany movements of the Tyranids - perhaps some high-energy funk or breakbeat would have been better. In terms of colour, it was all a bit dark, too. Quite funny overall, though, and excellent graphics. Not bad at all, but didn't live up to what it might have been.
