(Side Quest) Go to MSI (you'll be directed to him via waypoint), talk to the leader, Sanjar. Although you can be an ass to him, resist the urge and agree tp help him out. Upon completing the storyarc you can go back to the Broker and tell him that they have stopped broadcasting. You must help MSi to finish this trophy
