Somewhat story related and aquired by taking down the boss El Yayo, Head of Production. To get to him you need take out some or all of his underbosses; La Gringa, El Wey, Marcus Jensen, Madre Coca and El EMisario. This is done by completing the main missions in each area marked with a yellow arrow followed by a yellow crown. To unlock the main missions you need to find all the yellow main mission intel folders throughout the region map.
