Revolver: The Tarnished Star – the fourth in a series of expansions for Revolver – adds an optional "duel" scene at Rattlesnake Creek and an extra decision for the McReady player that may equip the imprisoned Santiago with a hidden weapon.
Revolver: The Tarnished Star also includes new cards for both players that give them the opportunity to customize their decks, bringing new variety and replayability to each game.
