Buck Wild medal

Shotgun Riot (unconfirmed name) is a new multiplayer medal in Halo: Reach, first seen on a screenshot of the new Bungie.net medals page. It is awarded when a player gets 15 kills with a Shotgun without dying, it is represented as a Running Riot! medal with three shotgun shells in the middle. The medal's official name remains unconfirmed, however if Bungie's naming convention continues as it has done with the new Be the Bullet medal, then the final name is probably something shotgun related.
