Nice...
But if Master Chief is shorter than Mario, he's a pretty short guy...
Anywho, on with the flash:
Graphics: Nicely done sprites...never imagined Master Chief as a sprite in the first place...but okay. Nice usage of sprites, I thought it would make a lot more sense if the lasers from the left side of the screen didn't just STOP at a certain distance, but either faded as it got farther like the real thing or at least trail off screen. Other than that great job! I especially liked the Warthog.
Audio: Didn't care much for it, but it was the entire spine of the flash, so it's 'aight.
Interactivity: Preloader, start button, and replay button. Common set that does the job.
Humor: I thought it was pretty funny.
Violence: Mediocre violence...especially for Halo!
Style: Pretty creative, but what's the connection between that song and Master Chief?...
Overall: It's coo'...
Phobos Technology, Phobotech.
BTW, Please don't tell me you really talk like you did on "Crack the Cookie" because that was just terrible voice acting...it sounded like Pat from SNL or something...anywho, Peace Out, Victor...
