Fortress factories are heavily fortified facilities dedicated to the production or extraction of goods in a specific area. Normal facilities are open to crime or raiding, but fortress factories can shrug off the common rabble with ease. Private security firms make a killing protecting these, while a highly dedicated and well-equipped force could snatch a good profit from whatever they can find inside a compound. Foreign companies doing black operations specially love fortress factories as they prevent them from being detected, give them a feeling of security and protecting their valuable assets.
