Hidden trailer
Allow the game to remain idle for two to three minutes at the main title screen. The screen will fade and a trailer for Kingdom Hearts 2 will begin playing, showing the credits with an instrumental version of the theme song "Sanctuary" playing in the background.

Drive mode training
Go to Timeless River. Make sure your Drive is full. Pick any of the four doors in front of you and enter it. Kill all the Heartless in the area with any transformation then return to Disney Castle before your Drive gauge is emptied. When you return to Disney Castle, your Drive meter is full again. Keep doing this until your Drive level is at maximum.

Drive mode costumes and intermission sequences
If you finish fighting a Boss while in a drive mode, the costume will remain in the drive form. However the character you fused with will still appear in the intermission sequence after the fight.

Drive meter refill
If your Drive gauge is almost empty when in your transformed state, quickly go to a save point and go to Gummi Ship. Then, go to any world desired. When you are in the world selected, notice that your Drive gauge is full.

To fill your Drive gauge up to maximum, go to the "Underworld" and replay the first round of the Cerberus Cup (not Paradox). Then, quit the round. You do not have to do any fighting. Your Drive should be at maximum when you return to the entrance.

Health refill
When you have low health and no magic or potions, but a fill drive meter, turn into any form. You will have full health.

Anti Sora/Anti Form transformation
When you Drive gauge is at 4, check you transformation. If you only have one transformation that would be the Anti transformation. If your life is on the red and your gauge is full, press Triangle and you will be in your anti transformation.

If your life is on the red and your gauge is full, press Triangle and you will be in your Anti transformation. You must to check if there is a reaction before pressing Triangle.

To go into Anti-Form you need enough Anti Points, which are obtained through changing into forms. Master, Valor, and Wisdom Form give you 1 Anti Point. Transforming into Anti Form makes you lose 4 Anti Points. Transforming into Final Form makes you lose 10 Anti Points.

Final Form
After the intermission sequence where Sora faces off against a member of Organization XIII in The World That Never Was, you can unlock the Final Form. Like The Anti-Form, this drive appears randomly during a battle. However, after you have used it once you can use it whenever desired. The easiest way to do this is to go to Olympus Coliseum and enter the Cerebus Cup. By doing this you can use your Drive gauge to transform, and if you do not get it immediately you can press Start and retry. Do it again until you get the Final Form.

Use the following trick to unlock Final Form or Anti-Form at will. This is good way of increasing your chances are to finish The World That Never Was and let the door to Kingdom Hearts open. Instead of completing the game, fill your Drive up and go back downstairs. Drive into Master form and let the Nobody with the red blocks hit you until you are about to lose the form. Retreat back up the stairs to use the Form cheat, then go back down and repeat the process until you land a Final Form drive. At that point, return to the stairs and save the game. Note that low health or Drive abuse does not increase your chance of an Anti-Form drive.

To unlock the Final Form, when you are fighting the Nobody in Organization XIII use the Master Form transformation. If Sora transforms into a silver and black suit with both Keyblades floating behind him, immediately revert back to his original state. When this is done, check your Drive Forms. Final Form will be available.

Goofy: Nobody Guard
In order to get Goofy's second best weapon, Nobody Guard, find and kill the Gambling Nobodies. Note: This may take some time.

Sora: Ultima Weapon
Sora's Ultima Weapon is obtained through item synthesis. Once you have obtained seven Orichalcum+s and the other ingredients, you will be able to synthesize it if you have an Energy Crystal. Note: You must be at least a level 2 Moogle to use energy items (for example, shards, stones, gems, and crystals). The items required are as follows.

Ultimate Recipe
Go to the mansion in Twilight Town. This is at the end of the game when you go with Sora. Once the machine is up and running to go to Roxas's Twilight Town, do not enter it. Instead, go through the other room where you went to fight Axel With roxas at the start of the game. Then, go into the next room with the hallway with the pods where Goofy and Donald were found. There are a few chests in there. The Ultimate Recipe is the in the chest next to Donald and Goofy's pod.

Seven Orichalcum+
1. Clear Atlantica.
2. Clear 100 Acre Wood.
3. Find the chest in the World That Never Was at the Brink Of Despair just before you go into the castle. There will be a big chest next to the save point. This is not the Orichalcum+. Turn around at this location and follow the short path across from the save point with the Orichalcum+ chest.
4. Clear Goddess of Fate Cup in the Underworld Coliseum.
5. Chest in Twilight Town, in Sunset Terrace where you went earlier in the game for the Seven Wonders. Jump on top of the train and you will see a chest on the roof of the big building (the one closest to to the sunset station).
6. Chest in Space Paranoids during the second visit there, just before you fight Commander Sark and the MCP.
7. Collect every single material in the game and give it to the Synthesis Moogle. He will give you an Orichalcum+. You need every single material (shards, stones, gems, and crystals, including a regular Orichalcum).

Other ingredients
Energy Crystal: Required to halve the amount of Orichalcum+s you need. Dropped by Bookmasters in Radiant Gardens (Hollow Bastion) near Merlin's house. These are the characters that float with green hats and books.

Twilight and Dense Crystals: Nobodies on Naught's Skyway. Go to naught's skyway just after the Hall Of Empty Melodies. Fight the Nobodies there and they will drop Twilight and Dense items.

Serenity Crystals: You can get these from the Moogles for giving them complete sets of materials.

Mythril Crystals: Found in random item chests

Donald: Enemy weapons
It is possible for Donald and Goofy to get enemy-based weapons, just as in the original Kingdom Hearts. To get Donald's enemy weapon, the Nobody Lance, kill some of the Dragon-like Nobodies that carry spears until you get one. It is his second best weapon. To get Donald's enemy-weapon, the Shaman's Relic, go to the Pride Lands. Go to Wildebeest Valley. Equip Lucky Lucky to all your party members and defeat as many Shamans as possible. Sooner or later you will get the Shaman's Relic.

Goofy: Enemy weapon
To get Goofy's enemy weapon, the Akashic Record, kill some of the book-wielding Heartless in Hollow Bastion/Radiant Garden. It is his second best weapon.

Hades Paradox Cup
Have all four drive forms and summons maximized at level 7 to unlock the Hades Paradox Cup, which is a level 99 Underworld Coliseum tournament with 50 rounds.

Fenrir
To get the most powerful weapon in this game you must defeat Sephiroth. Be careful, because he has fifteen health bars and is very strong. To fight him, go to Radiant Garden/Hollow Bastion at The Dark Depth area (beyond the area where you must defeat 1,000 Heartless). You can only fight with him after you defeat the MCP (Space Paranoids). After you defeat him, you must talk to Cloud (you can see him at Market Place of Radiant Garden/Hollow Bastion). Then, talk with Sephiroth again. After that, you will get Fenril, which as a 7 Atk and 1 Mag.

Battle Of A Thousand Heartless
Despite the name, this battle can be very easy. Equip Oathkeeper and the abilities Reaction Boost, Explosion, and EXP Up for some extra levels. First, use Rising Sun to get yourself into a corner. Then, keep on using air combos on the floating Heartless and ground combos and Rising Sun on the infantry. Whenever you can, Snag a floater and use Sparkle Ray, then finish off the survivors. Oathkeeper will give you fast powerful combos; Explosion can kill about eight Heartless every time you use it; and EXP Up will ensure that you get lots of levels if you have low health. After the fight you will see some intermission sequences, have a chance to go back to other worlds and finish them, and obtain the Gullwing keychain from Yuna, Rikku, and Paine.

Defeating the Grim Reaper
When facing the Grim Reaper the second time, have Donald and Jack in your party. Have Donald and yourself cast Blizzard and Thunder then pick up the medallions. Use the reaction command Hinder and the combo move Loot Launch when the Grim Reaper starts taking medallions from the chest. When all of the medallions are in the chest, switch Donald for Goofy then transform into Valor and keep attacking. When you transform back to Sora, switch Goofy for Donald then repeat the strategy. If you accidentally transform into Anti-Sora (black Sora with yellow eyes), lock on and keep attacking.

Defeating the last Xemnas
You must be at level 50 to do this trick. At the beginning, Xemnas will throw you into the air and say "We shall go together". When he does this, continue to use "Reversal" by pressing Triangle until you cannot do it anymore. Make sure you dodge all of his attacks, especially the ones with his double swords. These attacks can instantly kill you if you are not at full health. When he says "Mine", he will throw energy at you. Quickly use "Reversal" to get closer to him so that you can attack him. When half of his health is gone, he will begin to shot lasers at you. Try your best to dodge these, but it may be difficult. After he is done doing that, Riku will have to save Sora, but Xemnas will try to stop you by throwing orbs or hurting you with his shield. When he attempts to use his shield, have Riku use Dark Aura until he has backed up far away then continue towards Sora. Continue to do this until you have a command at the top labeled "Rescue" by pressing Triangle. After doing that, Xemnas will throw you into the air again. Do the same as in the beginning. Continue to dodge attacks and use "Reversal" to get closer to him. Make sure that when he is at his last bar of health, that both Sora and Riku have a lot of health. Xemnas will completely change the battlefield and send lots of lasers at you. First have Riku reflect them by pressing Triangle, then when your health is low, deflect them by pressing X. You should survive until then end of the frenzy. Then, simply attack Xemnas to finish the battle.

Defeating Sephiroth
Put on Berserk, MP Rage, MP Haste, and Trinity Limit. First attack him with Trinity then use Berserk immediately afterwards. When he teleports, quickly run away. Dodge him until he uses the big sword combo. Press Triangle as soon as it appears to block it and leave him open. Then, use Trinity on him, or if you do not have your MP back, keep attacking with Berserk. Make sure to hit him when he says "Sin Harvest". Note: Ultima Weapon helps a lot.

It is recommended that you be at level 85 in order to get Second Chance ability. However, it is possible to do it at level 65 when you get the Beserk Charge. The abilities you should equip are Guard, Finishing Leap, Retaliating Slash, Guard Break, all the Aerial abilities, Once More, Defender, Finishing Plus, and Berserk Charge. Item Boost, both Combo and Aerial Combo Boost are also recommended. Your armor and accessories do not make a difference in this battle. Make sure you fill all you item slots with Hi-Potions, as Elixirs will just be a waste. Set your shortcuts with Hi-Potion, Cure, Reflect, and any other command. Sephiroth has eight attacks, all of which are possible to dodge and counterattack. The first attack is his Dash attack. Simply block it with the Reaction command. His Sword Combo can be blocked by using Guard or by running away and counterattacking when he finishes. His third attack is the Upward Slash. You can either Guard it or get hit and use the Retaliating Slash before he can begin a combo. His Dark Orb attack can be dodged by either attacking them or by using Reflect. The Flame attack can only be dodged by running away. If you get to close you will be sucked in and thrown to the other side. His trademark attack, Sin Harvest, is incredibly deadly. You can either hit him before he gets too high or ready a well timed Cure of Hi-Potion. After he uses Sin Harvest he always goes directly into a Dash attack. The seventh attack is his second trademark attack, Meteor. The only way to dodge it is to jump left and right. Should you get hit, use the Aerial Recovery and continue dodging. His last attack is an upgraded version of his Sword combo. It can be blocked the same way but you cannot run away from it. Note: If you get down to his last bar, make sure you have MP as the game will only let you win with a finishing combo.

Be at least level 65. For a weapon, equip Ultima Weapon. For abilities, equip Guard, Retaliating Slash, Slide Dash, Explosion, Aerial Sweep, Aerial Spiral, Aerial Finish, Counter Guard, High Jump, Aerial Dodge, Berserk Charge, Leaf Bracer, 2 MP Rages, Second Chance, Once More, and optionally Trinity Limit and Scan. For items, equip lots of Elixirs and Hi-Potions. Sephiroth will start with a move that slashes through you. You must use the action command to dodge it. If you did this, he will be left open for a free combo or two. When he teleports and knocks you into the air, use Retaliating Slash for a few hits on him. When he charges at you swinging his sword, use Guard until he is done, then attack him. Note: Make sure to block this because it takes away about three quarters of your HP. When you have knocked a few HP bars off him, he will send blue spheres around you. Destroy them quickly because Sephiroth will charge you and the spheres will hit you. This is where High Jump and Aerial Dodge are useful. He will eventually float up in the air and say "Heartless Angel". Double jump and attack him quickly. This move takes out all your MP and all except 1 HP (if you put on Second Chance/Once More). Make sure to block it. Also, be careful about the fire pillars. When you have whittled him down to 3 or 4 HP bars he will shoot down lots of meteors at you. Make your way to him and get him. You will eventually kill him. Make sure to use Curaga and items sparingly and only in emergencies.

Hollow Bastion: Waterway: Better vision
When you finish the Heart door puzzle after Riku fight #1 and go down into the base level, you will eventually go through a door to an area called "Waterway". If you cannot see in there, turn the contrast and brightness all the way up on your television.

Easy experience
Go to the "Pridelands" level and go into the King's Den. Then, exit to the Peak. There will some flying enemies. Kill them, then exit back into the King's Den. Go back out to the Peak and the enemies will have respawned. Repeat this as many times as desired.

Go to the "Pridelands" level. Put on the ability Experience Boost and equip the Gullwings Keyblade. Take off all healing abilities from your allies and get in a critical condition. Go to the peak of Kings Den and use Magnega to kill off a group of the enemies there. You will gain 30,000 experience points for defeating them. Once you defeat all of them, go back in, exit out, then defeat them again.

When you summon, your Drive gauge becomes the Summon gauge. Go to the Underworld entrance and make sure you have full Drive. Summon anything, such as Chicken Little. Because you get one experience point for every 1 point of Summon gauge used, you can get experience by just letting your game remain idle. As long as your summon is out, you will gain experience until the Summon gauge runs out. When you start out, you only need 6 points to get to Summon level 2. Summon, then just remain idle at the Underworld entrance until the gauge runs out, then repeat the process. Once your Drive gauge runs out, enter a tournament and quit it. You will exit with a full Drive gauge, then repeat the process. At 6 Drive Gauge points you can get from level 1 summon to level 7 (the maximum) in about one hour.

"The World That Never Was" is a good training location. For your normal levels, just fight all the Nobodies. For your Valor levels, go to Naughts Skyway and go to the area where a group of Nobodies come out. They also give you about 400 experience points. For your Wisdom form, just start right in the beginning of the level where all the Shadows are found. For Master form, go to Beast's castle and search it for Crimson Jazzes and Morning Stars. They mostly drop the big Drive balls, and you will get 3 experience points. For the Final form, go back to Naughts Skyway and kill all the Nobodies that keep reappearing.

You will need the Gullwing Keyblade and the Experience Boost ability for this trick. After you complete Pride Rock, equip the Gullwing Blade. When your life is critical you will get more experience with it. Put on the Experience Boost ability. Make sure you turn off Donald's and Simba's healing abilities. Go through the King's den and go up to the peak. You will see a number of little yellow flying Heartless. Do not attack them yet. Allow them attack you until your life gets to critical level. After that, start slaughtering them. After you kill them, all go back to the King's Den, heal, then do it again.

When the Heartless attack The Destiny Islands, stay there and kill them. They only give 1 experience point, but they are easy to defeat.

Go to the "Pride Lands" after completing it a second time. Go the area where you defeated Scar to find a lot of Rapid Thrusters. If you defeat all of them, you will get 12,656 experience points. You can repeat this battle by going to the Stone Hollow then going back to the Peak. There are 226 Rapid Thrusters.

Easy gold
To get gold quickly, go to the Mansion in Twilight Town. Have your characters set on Sora Attack and go into the large open room. Make the Gamblers appear, but do not kill them. Instead, keep playing there card game action command. Having both of them out at the same time and your characters equipped with the abilities to make more gold fall and more items drop will let you get up to 500 gold per game, and even the Nobody Defense shield for Goofy. Since this does not kill the Gambler, it can be done repeatedly. Wait for the Xs and Os to slow down to achieve an easy win.

Leveling up Final form
To level up the Final Form, go to The World That Never Was at The save point just before the door to Kingdom Hearts. The theory behind the transformation is that fighting a Nobody while in drive form increases your chances of unlocking Final Form, and fighting Shadows increases your chance of an Anti-Form drive. It seems that getting hit increases your chances even more than hitting them. The number of hits raises the chances dramatically when in a combo. Like the Combo Boost lands a critical at the final hit of a combo based on the number of hits in a combo, the chances raise even more while the combo the Nobody/Heartless does is both long and completed. The red block Nobody has a huge combo and always lands the final blow. You are almost guaranteed a Final Form unlock using those Nobodies. One happens to be near the last save point, which is a separation map (zoning to that map utilizes the Drive cheat). It is the best place to level Final Form, because finding Nobodies in abundance is difficult at the end of the game -- sspecially since the Final Form uses up the drive gauge like never before.

To level up the Final Form, go to Twilight Town and enter through the tower area where Master Yen Sid presides. Go outside and defeat as many Nobodies as possible. Then, return to the save point, exit the world, and repeat.

To level up the Final Form, go to "The World That Never Was" and land at the Proof of Existence room. Then, go up the stairs directly ahead of the save point to get to Naught's Approach. Once the Nobodies appear, change into Final Form and start attacking. If your Drive Gauge goes to one, go back into Proof of Existence then go to the world map from the save point.

Final Form levels up based on the number of Nobodies destroyed. This is easy to do at Yen-sid's tower in "Twilight Town", accessed by the blue train at the station. Remember to do this near a save point. Whenever you are in a Drive mode you can exit to the world map and land in the same location. This will restore the drive gauge to maximum.

To easily level Final Form, go to "The World That Never Was". Go to either Proof Of Existence, or Twilight's View. Go to Naughts Skyway and go to the section where there are many Creepers. Wait until there are quite a few of them. Then, use Final Form and just keep attacking. You should be able to destroy 15 to 45 Nobodies.

Leveling up Master form
In order to level up the Master Form quickly, go to the land on Dragon's throne room. Go out the door and switch to your Master form. Kill all the Heartless there. The Drive Orbs should give you about 75 experience points for Master Form. To kill the enemies in the hallway faster, use your Thunder magic. When all the enemies are dead, run back to the save point before your Drive gauge reaches zero. Then, go to the world map and repeat the process.

To level up the Master Form, go to Land Of The Dragons, throne room. Kill the horsemen using Oathkeeper and follow the Wind Keyblades. Attack by four attacks, Fire magic, and four attacks again. This will kill them in about two seconds apiece. You will get 90 experience points for each run, and Follow the Wind ensures that you collect every Drive Ball.

To level up the Master Form, go to Aladdin's world and enter through the peddler's shop. Go outside and defeat as many Heartless as possible. Then, return to the peddler's shop, exit the world, and repeat.

The Master Form levels up by collecting Drive Orbs. The best place to do this is in the "Land Of Dragons".

Go to Beast's Castle and enter the parlor. First, go to the front doors and kill the Morningstars and the Statues outside. Run back inside and go up the steps. Kill the Crimson Jazz and Morningstars. If at anytime you are on your last Drive bar, go to the save point and save. Eventually you will be able to go all the way to Beast's room, gaining anywhere from 25 to 150 experience points each time.

Leveling up Wisdom and Valor forms
To level up the Wisdom or Valor Form, go to The World That Never Was. At the first save point, kill the never ending Heartless. Because you have six gauges, drive, run out, drive, and return to the world map. Unequip all specials by Goofy to ensure that you get the kills. Also, equip his default weapon.

To level up the Valor and Wisdom Form, go to Timeless River and enter Mickey's house. Defeat all the Heartless and continue on to the scene of fire. Defeat all the Heartless and continue to the Lilliput area. Defeat all the Heartless, then exit Timeless River and repeat. You may need to exit Timeless River earlier, depending on your form level.

For the Valor Form, experience depends on the number of hits you land on enemies. Try fighting in the Borough at the "Radiant Garden"/"Hollow Bastion" world, the second time around.

Because Wisdom Form gains experience for every Heartless destroyed while in that form, try fighting at Fragment Crossing in the "World That Never Was".

To easily level up the Valor, Master or Wisdom Drive form, first complete Space Paranoids. Next, go to any one of the four starting points for that level (for example, pitcell, I.O. com. tower, etc.). Next, go to a group of enemies (preferably with Devastators for Valor and Master, or weak enemies like Strafers for Wisdom) and change to your form. Kill all the enemies in the level. Then before you switch out of Drive mode, go to a computer terminal and leave Space Paranoids. When you return to Ansem's study, you will have full Drive health and magic. If you do not make it and your Drive runs out, go to Olympus Coliseum, enter any tournament, and quit. You will have full Drive. Then, just go back to Ansem's study and repeat until you have the desired Drive level.

Revive character
If you die against certain bosses you can revive yourself as Mickey with the command "I won't give up" (for example, against the Shadow Stalker and Dark Thorn Bosses in Beast's Castle and Xaldin when you return to Beast's Castle). Mickey is better than Sora and has stronger attacks. If you cannot defeat the Boss with Mickey you must revive Sora and his party.

Fatal Crest Keyblade
Complete the The Goddess of Fate Cup in the Underworld.

Restore magic
In Cave of the Dead: Entrance (Olympic Coliseum), clear out all the Heartless/Nobodies. Then, use Magnet and all the floating white balls will explode, emitting magic. This is a quick and easy way to restore all of your magic.

Enemy items
Both Donald and Goofy can get enemy items. Goofy gets the Heartless Shield and the Astackick Record. Donald gets the Nobody Lance and another item.

Heartless Shield: Go to Port Royal and keep killing all the enemies until you get one.

The Bouncer references
On two occasions, there are references to the old Square game called The Bouncer. The first of these is Roxas. His hair is similar to that of Sion Barzahd in The Bouncer, and he also wears a similar necklace. The second is Pence. His jersey clearly reads "Dog Street" on the right side of his clothing. This is Sion Barzahd's favorite brand as well.

Kingdom Hearts: Chain Of Memories reference
While in the white room in the old mansion in Twilight Town, the options on your menu (lower left-hand corner) are marked with Kingdom Hearts: Chain Of Memories cards.
