Yeah, remember that? Word's going 'round that if you send that in to Valve - like, actually mail it, in an envelope - they send you info on a product called the Ambassador. Also, the Spy achievement - Diplomacy. New weapon? Perhaps the effects of the Gun V. Engineer in Meet the Spy. Though I don't see the Spy as a "Boom Headshot" person, only time will tell. Edit: Could be a Peacemaker, as many non-steamforumtards have suggested. Ambassador = Peacemaker... kind of.
