Your back's against the wall and you're facing impossible odds, chances are you aren't going to walk away from this one... But damn it, you're sure as hell gonna take as many of these bastards with you as possible...

What music do you want playing in the background as you go down fighting?

This will be my backup!


You just HAVE to love Ennio Morricone.

If not I'll settle with:

[Yokai]

Hmm, depends on the weapon and the enemy, I think.

Spoiler: Guns against gas mask mooks

Spoiler: Sword against orcs/skeletons/etc.

This would be entirely slow-motion of course.

Spoiler: .357 against just about anything
