Kingdom Hearts Birth by Sleep Walkthrough

Birth by Sleep is different from the other Kingdom Hearts, because you can play with three characters, each following a different path. You will need to complete all stories to truly finish the game.

I decided to follow the recommended order to play with them: Terra, then Ventus, then Aqua. Of course, you are free to choose a different order, even though the story might get confusing – or maybe less surprising at times, depending.

This is a full walkthrough, meaning you will also find treasures location and advice for boss fights. I played in Critical Mode while writing it, so some fights might be easier and require less stategy than this guide suggests.

If you want a basic walkthrough, I invite you to read the Birth by Sleep Speed Run guide instead (not yet available). On the contrary, the 100% completion guide will tell you everything you need to do and when.

This guide was made while playing the Final Mix version. A PSP guide will be redacted at a later date.

First game

After the cut scene, you will take control of Ventus. This is a classic tutorial. You can try out all characters in combat, and later, you will have to choose one to start the game.

Terra's path

Land of Departure

After another cut scene, you are thrown into a fight. You will receive a Maximum HP bonus and the Critical Impact Command Style.

When the next cut scene is over, you will unlock Ventus and Aqua's D-Links and the Land of Departure (Keyblade) Command Board.

Enchanted Dominion

Waterside

You have to fight groups of Unversed right when you land.
Search the area a bit to find the two chests and then go to the only available exit.

Forest Clearing

Follow the path. You will have to cross a long bridge and kill some Unversed on the way to the castle.

Audience Chamber

Don't mind the sticker for now, as you can't reach it until you have specific abilities. Go up the stairs.

Hallway
Aurora's Chamber

After a cut scene, you unlock Maleficent's D-Link.

Tower Room

Before turning back, you can go to the Tower Room to get a few treasures. Then, go back to where you came from, all the way to the Audience Chamber. Get ready for a boss fight.

Wheel Master

While playing Kingdom Hearts, you will notice that learning bosses patterns is important, especially on higher difficulties.

The Wheel Master has three parts that you can target: himself, his wheel and his spindle. You can destroy the last two to make things easier.

When you hit the boss enough with combos, it will be stunned for a few seconds. Don't let this chance slip by!

You receive a Deck Slot, the Diamond Dust Command Style and the Fairy Stars Keyblade after the cut scene.

Land of Departure

You might as well get the treasures there now.

Mountain Path
Summit

Castle of Dreams

Forest

You are thrown into a battle with Unversed upon arrival. After the fight, turn around and go to the next area to get a treasure and sticker.

The Chateau

Go back when you are done and this time, head towards the castle.

Palace Courtyard

In the water, you might find special enemies that drop ice cream ingredients. You can't use them yet, but if you are a completionist, you might as well start gathering them now! The Unversed will despawn at some point, so you need to be fast. Every time they receive damage, they drop an item. It's best to hit them weakly but fast to get more items.

Go up the stairs to continue the story.

Corridor

You will fight a lot of Unversed while Cinderella walks on her own. In the corridor, stay close to her, because some monsters will spawn behind her. In the next room, though, once you have beaten the first wave, you can go on ahead a bit, as long as you don't go too far away. You receive the Counter Hammer command as a reward. You can equip it now under the Block command.

Foyer

After the cut scene, go down the stairs, then on your left.

Passage

You need High Jump for the sticker.

Antechamber

Head to the Balroom and get ready for the boss fight.

Ballroom
Symphony Master

This boss has four parts: himself, and three instruments. He's kind of slow, so you shouldn't have any trouble reacting to his attacks.

If you hit the maestro enough, it will fall for a short while. As for the previous boss, take this opportunity to use your commands!

Stop and Poison both work on the instruments.

After the fight and the cut scene, you receive Cinderella's D-Link, the Stroke of Midnight Keyblade and unlock the Castle of Dreams (Royal) Command Board.
Don't forget to come back for the chest in the Palace Courtyard if you want, or wait until you have High Jump for the sticker (in a while).

Dwarf Woodlands

Magic Mirror Chamber

After the cut scene, you can save your game and leave the room.

Vault

There are several treasures in this room. Two big chests are actually Spiderchests, be careful when you open them.
On your right, you will see green bubbles; jump on them and they will push you upwards. There is another device towards the exit, and you have to use a fire command on it to activate it. Use the first one to exit the area.

Underground Waterway

You just have to follow the wall on your right to reach the next area, but treasures take time to get.
There is a wheel in front of you: hit it to open a metal gate, but only for a few seconds. It's located opposite the wheel. You will find a chest here and another wheel, which open two other gates. Jump down, get the first chest, and by the time you are done, you will have to do it again to reach the second gate, with two other chests. Unversed dropping ice cream ingredients might also spawn there.

You can't reach the sticker near the first wheel until you have a maxed out Air Slide.

Courtyard

One of the chests isn't reachable yet, as you need Air Slide for it.

Flower Glade

After a cut scene, you will have to fight several waves of Unversed. You obtain Air Slide. Get the two treasures of this area, then go back to the Courtyard and climb on the arch by grabbing the wall on the left, then Air Slide to reach the chest. Then, go back to the Mirror Chamber.

Magic Mirror

This boss will often make replicas of himself. You have to attack the real one to make the others disappear. Look at his face: he's the only one smiling.

After the fight and the cut scene, you obtain a Maximum HP Bonus, the Firestorm Command Style and the Treasure Trove Keyblade.

The Mysterious Tower

Before going inside, open the three chests in the area. In the tower, you will find another chest. You can then go up the stairs for a cut scene. You will need to come back with High Jump for the sticker in the Chamber.

Radiant Garden

Central Square

As always, you have to fight Unversed when you land. Open the chests and go to the next area.

Castle Town

After the cut scene, enter Merlin's House.

Merlin's House

Check the book to unlock The 100 Acre Woods (Honey Pot) Command Board.

Fountain Court

In this area, you need to jump on the water jet to get higher and use your Air Slide to reach other platforms more easily. You will have to wait until you have Sonic Impact to reach the sticker.

Aqueduct

Avoid walking in the water until you reach the Unversed that throw wind blades at you. When you get close enough, they stop their range attacks.

Trinity Armor

You won't be alone for this fight. Here are the boss' moves and how to avoid taking damage:

You get a Maximum HP Bonus and the Rockbreaker Command Style. After the fight, go back all the way to Central Square and go down the stairs.

Outer Gardens

You need High Jump for the sticker. Check the door in the middle of the area to access the Purification Facility.

Purification Facility

Get ready for another boss fight.

Braig

The fight begins with a long-range camera. Get ready to guard to send back the attack, and the camera will return to its usual position.

This fight is mostly about guarding, as you can reflect most attacks this way. Here are his moves:

After the fight, you receive the Dark Volley Shotlock and the Xehanort's Report 2. Come back after the cut scene to get the treasures in this area.

Disney Town

Raceway

After the cut scene, you can play the Rumble Racing mini-game. You can win it by using the shortcut each turn. You receive a Hi-Potion, unlock the race in the Mirage Arena as well as the Disney Town (Toon) Command Board.

You can come back after the race to get this world treasure chests.

Main Plaza

You can play the Ice Cream Beat mini-game in this area.

Gizmo Gallery

Use several Thunder-based attacks on the electric meter to activate the area machinery.
Jump on the Mickey-shaped cog and you will find two chests. Use the other cog and you will have a choice: left or right.
On the right, you will have to jump on four mechanical hands to reach a chest (Air Sliding from the last one to the platform is easier).
On the left, there are two hands and cylinders. Jump on them then Air Slide to reach a chest and the entrance to the next area. You can also reach the sticker with Air Slide.

Pete's Rec Room

This room is a bit special. You will have to be a pinball ball to reach chests and another area. The gate at the center will open after your hit enough bumpers. Look at the picture below for more information.

There is a chest on the left, two in the middle, one being sealed by the gate and the other near the exit to the Raceway. The last chest is on the right, near the ceiling.

You can reach the exit to the Raceway in the middle of the pinball machine. From there, you will be able to reach the sticker on the platform you can see from the roof, when you have Sonic Impact.

Olympus Coliseum

Be prepared to fight some Unversed when you land.

Coliseum Gates

You need High Jump to reach the sticker.

Vestibule

You have to win the games by defeating Unversed waves, then the boss (in two phases).

Zack

Zack is skilled with his sword, but this isn't the hardest part of the fight.

After a cut scene, you will have to fight again, and this time, Zack has new abilities in addition to the ones above.

You receive the Sonic Impact command, the Mark of a Hero Keyblade and forge a D-Link with Zack.

Deep Space

Turo Prison Block

Before reaching this world, you will have to defend yourself against Unversed while traveling on your Keyblade. You receive a Maximum HP Bonus at the end of the fight.

In the first area, use the elevators and Air Slide to get every treasure. The highest cell on one side can be reached with a High Jump (that you receive in this room) and Air Slide from the highest cell of the other side.

Turo Transporter
Durgon Transporter
Launch Deck

Use the computer to turn on/off the gravity and be able to jump higher. However, you can't reach the door to the Machinery Bay Access if the gravity is turned off, so you might want to go there first, to save some time.

Machinery Bay Access
Ship Hub
Control Room
Ship Corridor

You will have to come back after the boss fight to get two of the chests, as a door leading to them will open.

Experiment 221

This boss likes to fly around the field, so range attacks might be a good idea.

Ignite works pretty well for this fight, like with most bosses.

You forge a D-Link with Experiment 626 and receive the Hyperdrive Keyblade. The Deep Space (Spaceship) Command Board is also unlocked. As a side note, you can also unlock Pete's D-Link by playing this new board!

Never Land

Rainbow Falls: Crest

As always, you are 'warmly' welcomed by Unversed when landing.

Gully
Jungle Clearing
Mermaid Lagoon

One of the chests is a bit hidden: swim inside the small cave near the north-east exit.

Cliff Path

The big rocks can be broken by hitting them with a combo, or baiting a cannonball on them. You can also High Jump and Air Slide to reach a palm tree, which allows you to reach the highest chest in the Lagoon.

Cove
Skull Rock: Entrance
Skull Rock: Cavern

If you entered through the hidden entrance on the west side, you can reach the other platform by using High Jump, then double Air Slide + Sonic Impact.

Peter Pan

This boss will fly around the field most of the time, making it difficult to touch him without range attacks. He only has one simple attack: when he's flying and his hands start glowing, he will descend towards you and attack. There is really not much to this fight, and you only need to remove half of his life to win.

You receive the Blade Charge Command Style, and forge a D-Link with Peter Pan.
After the cut scene, go back inside the Cavern to fight some more. You are surrounded by flying Unversed. Defeat them to receive the Pixie Petal Keyblade as well as the Never Land (Skull) Command Board.

After another cut scene, you receive a second Keyblade: Ends of the Earth. You can go back to Never Land to visit the remaining areas and get a few more treasures.

Peter's Hideout
Rainbow Falls: Base

You need to High Jump then Air Slide + Sonic Impact to reach the sticker.

Badlands

After a cut scene, you receive the Dark Impulse Command Style.

Land of Departure

Master Eraqus

This boss excels at parrying your attacks, physical or magical.

You get a Maximum HP Bonus at the end of the fight, as well as the Chaos Ripper Keyblade and Xehanort's Report 8.

Now might be a good time to visit all the worlds again to get the stickers you couldn't reach previously. If you followed this guide, you should need the following ones:

Keyblade Graveyard

Seat of War

When you land, turn around to get the chests behind you. Then continue to the next area.

Twister Trench

In this area, you will see several tornadoes moving around. When you get closer, they will come towards you, and if they touch you, a fight will start. There are different patterns inside: normal fight, slow enemies, fast enemies or giant Unversed (this is the worst, in my opinion, they can be hard to target when they fly).

Fissure

You will find your last Save Point and Moogle Shop here. Get ready for the final boss(es)!

Master Xehanort and Vanitas

You can focus on Xehanort at this point. Shotlocks work well for this, but keep a close eye on Vanitas especially when you are targeting. When his HP reaches 50%, you enter the next phase.

Master Xehanort

Tips are incoming.

Between phases, you will receive a Maximum HP Bonus, and be rewarded with the Xehanort's Report 2.

Congratulations, Terra's path is finished! If you followed this guide, you still have two stories to complete. Let's go!

Ventus' path

Please note that this section will be way less verbal than Terra's, as most information are already given there. However, you will find maps for Ventus for every world and the list of treasures, as well as boss advice and the like. Basically, if you feel like you're missing information, it probably is in Terra's walkthrough, and you should be able to find your way easily just by looking at the map and following the given area order.

Land of Departure

After another cut scene, you are thrown into a fight. You will receive a Maximum HP bonus and the Fever Pitch Command Style.

When the next cut scene is over, you will unlock Terra and Aqua's D-Links. Ensues another cut scene after which you will receive the Xehanort's Letter and unlock the Land of Departure (Keyblade) Command Board.

Dwarf Woodlands

Mountain Trail
Mine Entrance
The Mine

You have to find the dwarves. Go straight ahead to find a chest, and two dwarves in the crates to the right. Be careful, one of them defends himself!
Follow the path and you will find two other crates, one of them running away from you. Further ahead, there is another one that is even faster.
Finally, hit mine cart a few times – be careful not to stand in front of it!

Cottage Clearing

Follow the river to find the chest with Poison inside. To reach the sticker, jump on the stump, then towards the sticker while hitting with your Keyblade.

The Cottage
Deep Woods

After a cut scene, you have to protect Snow White while she crosses the woods. Stay close to her since she tends to wander a bit. You receive a Maximum HP Bonus.
Go back into the woods and get ready for a boss fight.

Mad Trent

This boss is easier to defeat with range attacks, since the poison puddles are released close to it. Strike Raid and Shotlocks work pretty well.

You receive a Deck capacity Bonus, the Firestorm Command Style, the Treasure Trove Keyblade and forge a D-Link with Snow White. You can come back if you want to get the chest in the Flower Glade, past the Deep Woods.

Flower Glade

Castle of Dreams

Mousehole

After the cut scene, continue to the left.

Cinderella's Room

Jump on the yarn ball to make it roll. It will help you reach higher grounds: the chair so you can jump on the dresser, then the bed from where you can jump on the bedside table. When you're done, go back to the Mousehole.

Wardrobe Room

In this room, you have to gather several items.

You can reach a chest by jumping on a furnishing with the yarn ball. You will find another chest on a pile of boxes. Go to the Mousehole again but through the north-eastern entrance.

Mousehole

Use the forks to reach the highest platforms. You can either go right or left here.

Wardrobe Room

If you went to the left, you get the Pink Thread and you can walk on the books to reach the last chest of the Wardrobe Room. If you chose the right path, you get the White Button.

After a cut scene, go back to the Wardrobe Room and get ready for a boss fight!

Lucifer

Like the previous boss, it will be easier to attack him from afar. However, when he jumps on you, avoid and then quickly come back and hit him so you can ride him with □. Press the buttons being displayed and he will be temporarily stunned after a few times. Use the Bronco Strike when available! And there is really not much more to it.

You receive the Diamond Dust Command Style, the Cinderella's D-Link, the Stroke of Midnight Keyblade and unlock the Castle of Dreams (Royal) Command Board.

Enchanted Dominion

Aurora's Chamber

You need to go all the way to Forbidden Mountain, past the Waterside. You can get the chest in the Tower Room first.

Tower Room
Hallway
Audience Chamber

You need Glide for the sticker.

Forest Clearing
Waterside
Forbidden Mountain
Gates

There are several chests here that you can't get before coming back later.
Be careful as Maleficent's minions are crawling around here. The ones with a pike will get close then attack, and archers will shoot at you from afar. You can make them run around wildly by using magic on them, or any kind of elemental attack, even if it's physical.

Maleficent's Throne

You will have to fight against Maleficent's minions. Use the same tactic as before so you're not overwhelmed by their numbers. Staying close to one of their spawn points can help as they won't surround you as easily.

Hall

I will give text explanations here, but the map above might be easier to understand. This room is full of invisible walls and colored teleporters. Those of the same color are connected.

Follow the wall to your right until you see the blue teleporter. Use it.
Follow the only available path and use the orange teleporter.
Go down the stairs.

Dungeon

When you get to the edge of the platform, don't fall down. First, you can get the chest on the isolated platform using Sliding Dash. Then, go back and jump to the other platform. Open the chest, follow the path to find some stairs and you will be back into the Hall.
There is only one way to go and it leads to a chest and a green teleporter. You will reach a dead-end with two chests. You can then go back all the way to the dungeon.
This time, fall down and go down the stairs to your right.
You are back in the Hall. There is only one way, with a teleporter that switches color between yellow and purple. Touch it when it's purple to get a chest and a sticker, go back, then wait for yellow.
Follow the path that leads to the red teleporter. After a cut scene, get back to Maleficent's Throne and get ready for a boss fight.

Maleficent

Depending on the difficulty you chose, she might be a bit of a challenge. Paying attention to what she says and where she teleports to will help predict her next move and act accordingly.

You receive a Maximum HP Bonus, the Thunderbolt Command Style and the Fairy Stars Keyblade.
You can come back now for the remaining chests at the Gates. Two paths unlocked.
First, when you enter the Gates, jump on the broken platform and again. Go to the right then up the stairs to find two chests. The last one is near Maleficent's Throne entrance. The corner of the wall to the left crumbled and you can jump on it too.

The Badlands

Masked boy

Tips incoming

You receive High Jump and Mickey's D-Link at the end of the fight.

Radiant Garden

Central Square
Gardens

Be careful in this area, as there are a lot of Mandrakes that can hit you from far away, even through bushes.

Front Doors

Come back after the cut scene for the chest, and if your High Jump is high level enough, you can also get the sticker. Then go back to Central Square, and follow the Unversed.

Castle Town

Go to Merlin's House before moving on.

Merlin's House

Read the book to unlock The Hundred Acre Wood (Honey Pot) Command Board.

Fountain Court

Use the water jets to reach the platforms. You can reach the sticker by jumping then hitting the air with your Keyblade, or using Sliding Dash.

Aqueduct

Be careful as there are Mandrakes in the water. Get ready for a boss battle when reaching the next area.

Trinity Armor

This is basically the same strategy as with Terra:

You get a Maximum HP Bonus and the Cyclone Command Style. Go back the Central Square and get ready for another fight. You will get the Reversal Command after the fight.
Now, go down the stairs to the south.

Entryway
Outer Gardens

After a cut scene, go back to Central Square–yes, again. You receive the Keyblade Frolic Flames.

Disney Town

Main Plaza

After the cut scene, talk to Huey, Dewey and Louie. You will need to help them make ice cream in the Ice Cream Beat mini-game. You unlock the Disney Town (Toon) Command Board. You can come back right away for a few chests.

Gizmo Gallery

Activate the machinery with Thunder-based attacks and/or the Thunderbolt Command Style. Use the Mickey-shaped cogs and the mechanical hands to reach the chests (two on the right and a sticker, one next to the cog, one to the left).

Pete's Rec Room

There is a huge pinball in this room, that you need to use in order to reach chests and the Raceway exit. There are two chests on the left, one in the middle behind bars (that will unlock once you hit enough bumpers), one next to the exit, and one next to the ceiling on the right, along with a sticker.

Raceway

You need the Glide Command to reach the Superglide chest. But you can already get the chest next to Pete's Rec Room entrance and the sticker on the right.

Olympus Coliseum

Town Near Thebes

You have to fight some Unversed when you land.

Coliseum Gates
Vestibule

Talk to Hercules. You have to break more urns than him in the allotted time. Hit the barrel to make it fall on the side and jump on it so you can break the urns faster. Be careful as Hercules can also use it!

You receive a Maximum HP Bonus. The second phase gives you a Deck capacity Bonus. After the cut scene, go back to the first area, where you will fight Unversed alongside Hercules. Commands like Gravity/ra/ga, Magnet/ra/ga or Tornado Strike work pretty well.

You're rewarded with the Air Slide Command, the Mark of a Hero Keyblade and forge a D-Link with Zack.

Deep Space

Before reaching the ship, you have to fight a boss Unversed. Attack when it moves around, and use your Barrier when it flails its tentacles or charges you. You don't need to kill it. You receive the Wingblade Command Style.

Durgon Transporter

After a cut scene, go back to the Durgon Transporter for the chest if you want.

Ship Corridor

You will have to fight several waves of Unversed in the corridor. Depending on the difficulty you chose and your level, I would recommend using the Mark of the Hero Keyblade to make things easier.

Control Room
Ship Hub

Use the computer to turn off the gravity so you can jump high enough. Turn it off halfway to get a chest then turn it on again to reach the door near the ceiling.

Launch Deck

You can block the guns attacks to throw them back at them. Get the three chests, turn off the gravity to get the fourth and the sticker, then turn it off again to reach the exit.

Machinery Bay Access

Machinery Bay

You will have to come back after the boss battle to reach the chests–except if you manage to get them during the fight. One of them is above the gravity computer, the other near the middle, up the bridge.

Ignite works well for this boss.

You receive a Maximum HP Bonus, forge a D-Link with Experiment 626, obtain the Hyperdrive Keyblade and unlock the Deep Space (Spaceship) Command Board.

Never Land

Seacoast

Turn around after landing to get a chest. You can continue this way to get another chest in the next area, then turn back.

Rainbow Falls: Base

You can get the sticker with a Sliding Dash, but you can also wait for the Glide Command.

Mermaid Lagoon

You can reach the sticker with two Air Slides from the little island with the chest with an Elixir inside.

Jungle Clearing
Peter's Hideout
Gully

Next, go to the Indian Camp.

Indian Camp

You have to fight waves of Unversed in the area. After that, go back all the way to the Mermaid Lagoon, where you receive the Glide Command after a cut scene.

Cliff Path

You can break the stones by hitting them with a combo or baiting cannonballs on it. A chest is hidden between one.

Cove

Get ready for a boss fight, and wait for it to be over to get two of the chests.

Captain Hook

Compared to Terra's boss when he was in Never Land, this one is much harder, especially if you're playing Critical. Ignite works well again, and being patient definitely helps.
Block and counter-attack and try to push him to the sides of the small island you're fighting on. When he staggers, just hit him to make him fall. The crocodile will love it!

You receive Peter Pan's D-Link, the Pixie Petal Keyblade and unlock the Never Land (Skull) Command Board.

Mysterious Tower

Mysterious Tower
Tower Entrance

Go up the stairs for a final cut scene.

You forge a D-Link with Donald and Goofie after the cut scene.

The Badlands + Land of Departure

After several cut scenes, you receive the Lost Memory and Xehanort's Report 9. It's time to gather the remaining treasures and stickers!

Keyblade Graveyard

Seat of War

Turn around after you arrive to get a few chests and a sticker, then continue towards the next area.

Twister Trench

If you already played with Terra, you know this area. Tornadoes will come towards you if you get too close and when they catch up, you will have to fight Unversed. The pattern inside can be either of: normal, fast/slow enemies, or huge ones. There are three chests in the middle, one on each side near the next area's entrance, and the sticker on the right side.

Fissure

Get ready for Ventus' final boss! To be honest, I found it harder than Terra's, probably because he's faster and I was level 20 or 25 when I did it.

Vanitas (first phase)

You get a Maximum HP Bonus at the end of this phase.

Vanitas (second phase)

Congratulations! You receive Xehanort's Report 10 and, if you followed this guide, you only have Aqua's story left.

Aqua's Path

Please note that this section will be way less verbal than Terra's, as most information are already given there. However, you will find maps for Aqua for every world and the list of treasures, as well as boss advice and the like. Basically, if you feel like you're missing information, it probably is in Terra's walkthrough, and you should be able to find your way easily just by looking at the map and following the given area order.

Land of Departure

After a fight, you receive a Maximum HP Bonus, the Spellweaver Command Style, forge a D-Link with Ventus and Terra and unlock the Land of Departure Command Board.

Land of Departure

Summit

Dwarf Woodlands

Cottage Clearing
The Cottage
Deep Woods
Flower Glade
Courtyard
Underground Waterway

If you came here with Terra, you already know how the gates work. If not, here is a recap: the first wheel opens the gate in front of it, next to the entrance to the Vault. Then, up the stairs, you will find a second wheel that opens two gates. You can't get both chests in one go so you have to open them twice. Also, unlike Terra, the Prize Pods are not behind the third gate, but at the Flower Glade instead.

Vault
Mirror

Tips incoming.

Enchanted Dominion

Forbidden Mountain

After a cut scene, follow the path up to the castle.

Gates

As always, this area is teeming with Maleficent's minions. They run around when hit with magic or elemental-based attacks.
Two of the chests can be opened a bit later, on your way out.

Maleficent's Throne
Dungeon Cell
Dungeon

You will have to come back for the sticker after getting Doubleflight, but you can reach the second chest by using a Sliding Dash, like for Ventus.

Hall

There are no invisible walls in the Hall this time–but no treasures either. Don't forget to open the chest next to Maleficent's Throne in the next room, then get ready for a fight in the next area.
You have to open the gates to escape. When your ally calls for you, use □ then X to jump. Don't forget to get the two chests you couldn't reach before.
You obtain High Jump when it's over.

As always, use Thunder-based attacks on the electric meter and use the Mickey-shaped cogs, hands and cylinders to reach all the chests.

When you land, you have to fight against Unversed, yet again. Exit the Control Room by the door on your right. There is nothing to get in the Ship Corridor, so keep going.

Durgon Transporter

You can either fight or ignore the Unversed and keep going until you reach the Ship Exterior. There is another scripted battle where you fight on your Keyblade. You can use the pillars to gain speed and rotate through the center, but using your Keyblade commands might be easier and/or faster. You receive Air Slide. You're back in the Durgon Transporter room. Eliminate the enemies and use the teleporter.

Turo Transporter

Go to the next area and get ready for a fight against waves of Unversed. You receive a Maximum HP Bonus and Aerial Slam. After the cut scene, come back in the room for the chests and sticker.
