Prison Architect — Going Green is a top-down real-time management strategy add-on. The expansion brings farming, exporting, and smuggling to your correctional facility. Now criminals will be able to grow potatoes, wheat, apples and much more. The harvest can be exported or used in local kitchens. But at the same time, you need to be prepared for a new type of smuggling, as prisoners can secretly grow unidentified herbs in the fields and steal ingredients from the kitchen to make booze.
The add-on requires the original version of Prison Architect.
