Before you depart for Citadark, Professor Krane will message you to meet him on the ground floor of his lab. Return there and he will show you a secret staircase into the basement, where he gives you the Master Ball.
There is only a single Master Ball in the game, and it will catch any Pokémon without fail, so be sure not to waste it.
When you are prepared, return to Gateon Port and depart for Citadark Isle in the Robo Kyogre.
Once you go inside the building, you'll find a healing machine and a PC. To the right will be Furgy, and to the left is an optional battle with Haben, who ambushes you from the ceiling.
Go to the elevator, Lovrina will come down and blame you for getting her in trouble by Greevil. She claims that XD001 is complete, and then challenge you.
After Bastil, continue down the hall and across the bridge through the center. You will find a box containing 5 Ultra Balls on the left side of the bridge. You will come across a door and another elevator guarded by Litnar.
The door on the right will lead you to a box containing 3 Hyper Potions, then you're free to continue up the elevator to 2F-1.
2F-1
There are several box puzzles here, pushing the block immediately after exiting the elevator will open the path to a box with 2 Revives, and pushing the block at the far right end of the room will open the path to a box with 2 White Herbs.
Grupel will ambush you as you attempt to enter the next room.
Go through the entrance after you beat the Hunter. Inside the next room, grab the PP Up. Go through the other exit to the previous room. There will be two more battles.
Go a little past them and you'll get an Elixir. Go back, past the Hunter and the Chaser, across the bridge, and you'll have to fight another Cipher Peon with two Shadow Pokémon.
The other entrances from 3F-1 will lead to the right side path with the PP Up, which you should have already collected. There is a hidden area to the upper right that cannot be accessed yet, so take the elevator up to 4F.
4F
You've made it out of the volcano! You'll see some moving platforms. Take the right platform and wait for the other platform to meet up with you. Take the adjacent platform down to the hidden room with two Max Potions. Go back up and this time, take the left platform. Follow the path down, only to be ambushed by a Cipher Peon.
There will be a stretch of ground below the spiral path. It will lead to a box with 1 PP Max. Head into the other entrance and you'll be in the same room, just on an isolated piece of land. The only way across is to wait for more moving platforms to take you up and over to the elevator. Take the elevator up to the next room.
5F
Take the Yellow hook and then the Pink hook. Grab the three Timer Balls in the nearby box. The rest of the hooks aren't accessible yet, so take the Red hook and go up the elevator.
Now you'll see glowing blue tiles, which, if you step on one, it will bring you back down to the lower floor. Grab the nearby chest which has three Max Ethers. Drop down the hole at the top-middle of the room.
While down here, grab the Max Revive. Take the orange hook, the pink hook, and the red hook. Take the elevator up again. Make your way to the northern wall, and make your way to the upper right.
Once on the right half of the room, head south and grab the four Full Heals. Drop down the glowing hole on the bottom right. Grab the two Revives. Take the cyan hook, pink hook and the red hook one last time.
Make your way back to the right side of the room and you will be attacked as you try to exit to the lower right.
Take the elevator up to 7F, which will be outside of the Citadark Isle Dome.
7F Dome exterior
Go left. You will be confronted by Snattle coming from the left side elevator, who is mad at you for embarrassing him on public TV. He will battle you so that Greevil will make him the governor of Orre.
After his defeat, he'll escape down the elevators again.
Remember that elevator at the beginning of Citadark Isle? The left side elevator is where it lead, and it's now accessible. When you first take it down, you have to go through a Cipher Peon.
After you defeat him, you can go inside the first floor entrance to heal your Pokémon. After you do, head back up the elevator.
In front of the big dome, you'll see Ardos, Greevil's bodyguard in blue.
After defeating him, you can head inside to find a healing machine and PC.
After a cutscene, Greevil locks you out of the interior of the building with a glass wall. Head back outside and start heading south, you'll be confronted by Gorigan who comes from the elevator on the left.
After defeating him, he will leave, and lower the glass wall, so you can access the healing machine and PC again.
In the top right corner of the room is a box with one Max Revive.
There are two optional fights with Cipher R&D, one is in the chair by the elevator you take up to face Greevil in the lower left.
When you are ready, take the elevator in the bottom left to the second level of the dome. Greevil will immediately challenge you, so only take the elevator when you are ready for the final battle.
Dome 2F
Greevil is waiting for you in the center of the dome, he congratulates you on ruining all his plans and exposing Cipher to the world, but his plans are complete.
He has already created a Shadow Pokémon that are "immune to purification", and intends to create an army that obey only him. XD001 descends from above.
Now is the ideal time to use your Master Ball and end the fight in a single turn, but if you want to save your Master Ball, be prepared for a fight.
After Shadow Lugia is snagged, Greevil will become extremely upset, cursing you for ruining his entire plan, and promises to completely destroy you and your Pokémon.
When the battle is finished, Greevil will fall to the ground, and Ardos will appear and say they should escape via helicopter and blow up the island with you, and everyone inside.
Greevil agrees at first, but Eldes steps in and convinces his father to turn themselves in to the authorities, as "the pure heart of this child won out over XD001, nothing remains of Cipher, we were wrong."
Greevil reluctantly realizes Eldes is correct, and Ardos leaves in silence. The storm around Citadark Isle clears and you return home. The entire Orre region celebrates your triumph over Cipher, and the credits roll. Congrats! You have completed the main story.
