Mafia III

This achievement can only be earned by assigning one Underboss (Burke, Cassandra, or Vito) all six optional districts (the first three are mandatorily assigned) throughout the course of the story. Once your favored Underboss has control over seven districts in the city, continue playing through the story while frequently checking the map to see when their kickback is available to pickup. Once their kickback is over $10k, head to their location and pickup the earning to unlock this achievement.

NOTE: Please keep in mind that this achievement will also lead to "Just You and Me" towards the end of your playthrough.
