From the publisher's website:

You're all bandits trying to rob this boomtown blind! Take down the bank, train, stagecoach, and even the brothel in this frantic and fun real-time dice shoot em' up! In Boomtown Bandits, players take turns placing two shooter tokens and a coward token around the town — face down to hide your coward's identity! All the tokens are then revealed. A Wild West "draw" occurs whenever any competing bandits try and rob the same location. This shootout is in the form of simultaneous dice rolling (with players rolling as many corresponding dice as they allocated tokens), and rolling is continuous until there's a hit or until a coward runs! Locations include seven loot cards, each with strategic weapons and abilities to help you in future fights. When any location is out of cards the game ends, bonuses are awarded and the bandit with the most loot wins! Who will rob the most money and be the baddest bandit of them all?
