After completing the mission "X Marks the Spot", you'll have to track down C3n50r807 one last time for a final mission. It's time to clean up the airwaves.
True Vault Hunter
Money: 4 Eridium
Gear: Grenade or Rocket Launcher
After talking to C3n50r807, you'll be sent to return to the Magnys Lighthouse. Not far from where you took the elevator up to the lighthouse proper, you'll find a house way out in the distance. To get to it, you'll have to follow the train tracks in the area and jump from section to section. Eventually, this will take you to the camp of the infringing DJ, Tanner.
Try and find some cover as soon as possible. You don't have a lot of room to back up so you want to be safe and start working on the enemies before you feel the need to pull back. Most, if not all of the enemies are going to be pirates here. There are going to be more than you expect so be careful trying to advance.
DJ Tanner himself is actually more like a Rat Bandit than a pirate. He doesn't scurry around as much but he hunches similarly. If you get rid of the regular Pirate enemies, taking DJ Tanner down shouldn't be too tough. He doesn't have any real exceptional qualities except for slightly higher health.
With the DJ dead, go around the north side of the house and find the ladder leading up. Climb to the top and smash the computer at the top. When it has been destroyed, return to C3n50r807 for your reward with the knowledge that you made Pandora a better place… for the children.
