Bier Pioniere: Bier Boom

From BoardGameGeek:

With our own House brand and further specialization, we are trying to differentiate ourselves from the competitors. Emerging by-products such as beer waste need to be managed, and we are tapping into new markets via the railroad. Some small changes can offer some new decision-making opportunities. This set contains 5 expansion modules that can be played individually or in any combination with the base game – however, we recommend not using more than 2 modules at the same time. Additionally, now you can enjoy Beer Pioneers as a new challenge in solo play. The rules and the necessary components for solo play are also included. -description from the publisher
