From gamewire: The new expansion has been co-designed by the sheriff himself, Emiliano Sciarra, designer of Bang!, and by some of the people who entered the contest held by daVinci and its partners, submitting new ideas for a card. With more than 500 entries, the jury had his tough time to select a fistful of them that will mark the history of gaming. The expansion is compatible with the original High Noon, so you can shuffles the decks together to have a different game each time! - BoardGameGeek
