Steam Park: Play Dirty, a modular expansion for Steam Park, allows you to introduce many different new features one at a time — or all together:

• New stands provide players with additional powers that allow for more diverse strategies to become the richest robot in town.
• Six new characters offer players help in building their amusement park, making every new game of Steam Park different and unique.
• Scary espionage dice allow players to copy the other players' actions, but at a cost!
• New rides that expand the old ones, making them more profitable as long as you can afford the cost up front.
• Components to allow for up to five players to enjoy the experience of creating an amusement park.
