This:
With the part where I die being at about 4:36
Stunning.
EDIT: In my mind, the circumstance is that the horde is approaching, and me and a couple others are fighting them off to buy the last of the survivors time to escape. As the last of them gets onto there jeep, they toss me my rifle. As I catch it, and load it with a reassuring click, the song starts. The jeep rumbles off, taking with it our last chance of survival, the horde appears over the horizon. In the happier bit in the middle there are some flashbacks to good times as the horde gets closer, still out of range. I am woken by one of my companions, and we man our barricade just as it goes into the 6/8 bit. The camera zooms out and up as no matter how many we kill, there are always several more to take its place.
And then I die just at, as I said, 4:36
