Thanks to Derek, who does this webcomic, for the remix of our action trailer!
You, too, can remix our trailer audio: you can find the raw .wav file, and a shorter version of the action promo here.
Members of the AMV community are strongly encouraged to cut AMV trailers to this promo and put them on youtube. I think the only anime with enough explosions to cover the sound effects might be Trigun, but there’s also some shuriken sounds in there.
