There's a duel mode in Chivalry now, thanks to the latest update. And boy is it a doozy, or it was while in beta: take a look at Criken2 here, who shows us how to duel like a champion/idiot. For the presidents. You'll even learn advanced tactics, like psyching your enemies out and tricking them into pressing the self-destruct button.
