this is great, thou few minuses in my opinion, that are basically a matter of taste...

first, "music" felt a little bit repetitive... second, robot(geth, or whatever...i cant remember their race name :) ) at the end...it has these mechanisms on his head, also a lens in his eye, that is a great visual material to make sound for (thou i noticed that you did almost the same sound as in original trailer)..

ok, the good thing is that i really like your version of glitches and letters typing/appearing over the original trailer ;)

p.s.: sorry for my not so very good english ;)

WOW! Well done. Love the glitch sounds, and the text as @Linas mentioned. I also like how everything goes quiet after "KILLED IN ACTION" for a moment.

I did find that the robot at the end was a little low in volume, would have liked to have heard more as the energy comes on, and the servos kick in, leading to the flare. Also I probably would have gone for more crescendo in the score at that point to REALLY kick the audience in the pants for the big reveal. That's the point you can really play with dynamics, building up to loud and then having it all go away as the name comes up. BUT... those are more taste/aesthetic things.

I agree with what's already been said about the metallic/scrape element ("music"), it's a bit repetitive and dulls the flow of the piece. It's texture is great though!

If you wanted to rework that element, I'd say to mess with the duration/timing of the phrases, change the frequency content, and apply some additional filtering every now and then. Give that piece of your design some movement and life, and it will really help your pacing.
