Accept the mission from Janey in Serenity's Waste tale the vehicle and jump the escarpment in the Northern part. This way, you will reach Concordia.
After you get there, follow the corridor, where you find a Cu5tm-tp. Wait for him to give you the ticket and take it.
Follow the robot along the corridors, and finally give the Orbatron to it.
Meet up with Nina, in the next part of the location and enter the decontamination device.
After the procedure is over, take the health now vial, from Nina and keep along your path.
Reach the lift in the center of Concordia and use it. After you see what has happened, head towards the Northern part of the location.
After you reach Moxxi's bar, talk to Roland and Lilith. Then, approach the counter and talk to Moxxi.
Head Northwards and, in one of the rooms, you will find custom claptrap. Talk to him and use the safe. You can collect the weapon from inside.
Follow custom claptrap and you will find a crate to collect moonstones from. The way to the stash is up the stairs shown in the screenshot.
After you collect the moonstones, go to Earl. You can find him in the North-Western part of the city. Buy an upgrade from him (any one that you like) and head towards the first transmitter.
Reach the location shown in the above screenshot and, thanks to this, you will get to the rooftops.
After you have activated the first transmitter, go West, towards the second one. Walk over the rooftops.
The second transmitter is electrified. Turn around and jump onto the nearby roof. You will spot a generator that you need to destroy (shoot at it). Then, return to the transmitter.
The third transmitter is on Concordia's main roof. Jump over to the nearby rooftop (where you have destroyed the generator) and then, onto the main roof. Destroy the turrets, along your path. After you deal with the transmitter, collect the remains of the turrets to repair the damaged transmitter.
After you have activated it, climb down and use the main console. Then, head towards the Concordia's exit. The exit is blocked off so, go to Moxxi's bar and talk to the waiter claptrap.
After the conversation with the robot, turn around to face the one hand outlaw. Use it and press the button. Enter the room and talk to Moxxi. Then, head towards the exit. Before you leave, you can report to her on the mission and collect your reward, i.e. class mod for your character.
