Revolver: Vengeance on the Frontier – the third in a series of expansions for Revolver – gives both players the option of buying cards from a separate, neutral Frontier deck with dollar coin tokens earned during the main game. Many of these cards feature a choice of useful options. Others are threats which can be played by either player, such as "Old Three Toes", a monstrous grizzly bear that is particularly difficult to kill.
The expansion further elaborates on the new winning condition added for McReady in Revolver: Hunt the Man Down, and many of the cards are also useful to both players at the San Manzanillo prison location.
Revolver: Vengeance on the Frontier also includes new cards for both players that give them the opportunity to customize their decks, bringing new variety and replayability to each game.
