BANG! Dodge City contains two decks of new BANG! cards, introducing new characters and new cards to shuffle together with the original deck. Moreover, it is possible to accommodate eight players: there are two Renegades in town!

The High Noon expansion is 13 cards: shuffle them and put the one called "High Noon" at the bottom. Each turn the Sheriff reveals a new High Noon card which every player must obey for the entire turn.
