We Are Roleplaying (W.A.R.) presents roleplaying in the Shattered Lands, a non-contact combat LARP with melee and missile weapons, and spells.
From the rules:
[These rules] provide you with a medieval style fantasy setting and you get to create a character that fully participates in the story. You will build your character from the ground up – race/culture, skills, costuming, etc. Once you design your character you will attend events, usually at a campsite, and actually get to become your character for the weekend. The difference between a LARP and a table-top roleplaying game is that instead of rolling dice, you’ll actually get to act out and partake of the story.
