Wrecking Crew

Wrecking Crew is a multiplayer medal in Halo: Reach, that is awarded once a player kills 15 enemies with the Gravity Hammer without dying. It was revealed post-beta along with several new and updated medals in the 05/28/10 Bungie Weekly update.

Trivia

 * The name of the medal is a reference to the 1985 NES game, which involved Mario using a large hammer to tear down buildings.
