This is interesting.
First, watch the Dead Island Official Trailer, with the sound on.
Kinda sad, isn't it?
Now, queue up some good zombie killing music (I personally use Rammstien's "Feuer Frei", but any nice, fast, busting heads open tunes should work), turn the volume in youtube off, hit play on both the music, and on youtube, and watch it again.
Not nearly as sad now, is it?
