You look down at your shiny new Desert Eagle and, yep, you're ready to blow this guy's head off. You don't know exactly where to find him, so you just think of places that would be good for a showdown and head there. Town square sounds appropriate, so you head to the middle of town and, yep, there he is, just waiting for you.
"Didn't think you'd have the balls to show," he says to you as you walk up.
"Who needs balls when you've got a .45?" you say.
"Damn good point," he says, lifting his own pistol to show you.
A brief firefight ensues, as per the usual tropes, and you both suffer a single grazing wound. A bullet clips your shoulder, and hurts like hell, but yours blasts a hole in your opponent's thigh, leaving him crippled, Now's your chance to act!
