The add-on “Biogas” expands the features of the original game by aspects of the green power generation. For that purpose, new expansions, crops and production cycles were added to the original gameplay. Harvest special crops for energy generation and transport these products to the biogas facility. In addition to the energy generation a complete new production cycle of the daily farming live was added. You can now mow the grass and bring in the hay. This classical task expands your possibilities and improves the level of realism in this simulation.
