When you visit the Dock Colony for the first time, a woman in front of the clinic tells you of a Fish Detector that her husband lost. Go to the Kukai Foundation's cleaning place and inspect the tuxedo to find the Fish Detector. Talk to the girl in the Iron Man bar, sitting at the lower left table. She says that she lost an important ring and asks you to find it. Go to the Private Beach and go in the water where the fish show up on the radar screen. Run up to every fish and press Circle. Sometimes you will get an item, and sometimes you will not. You can get a Med Kit, a Speed Stim, and the Engagement Ring. If you return to the beach on any return trips, the Med Kit, and Speed Stim will be there again. Give the ring back to the girl in the bar. She will give you the Decoder #8 to open the red door.
Whenever possible, fight. You will never know when a Boss is lurking around the corner. Utilize all of your T, E, and S points. Upgrade each attack accordingly and level up your characters. Also save your items (such as medkits and ethers). Whenever possible, evolve your Ethers. One of the most powerful character encountered using is KOS-MOS. She levels up quickly, and when she receives weapons and such she becomes more powerful. Note: In certain parts, KOS-MOS will not be a playble character. Keep your characters at even odds. The game is very unpredictable. Also take advantage of "Booster", as a lot of times you will die. All enemies possess the same abilities as you do. Whenever possible, stock up on Medkits and also upgrade your AGWS's.

Slide Deck Key
When you are onboard the Elsa, before the ship is attacked, you can speak to the repair robot in the A.G.W.S. hangar. He mentions that he is the hardest worker, and that while he was cleaning one of the cabins he lost his key to the Slide Deck. The key can be found on the couch in the lounge of Cabin 2 (the southern-most cabin).

Hazardous Area Map
On board the Elsa, you will see the pilot walking around in Hangar 1 (A.G.W.S. hangar), looking for a map. He does not give any concrete details, except to look everywhere, and that the captain wants it. To get the map, speak with the captain on the bridge. He will give it to you to take to the pilot.
Play poker in the casino long enough to buy the coveted Brave Soul. Then, either equip Jr. with it or have him extract and equip the skill. Jr. is ideal for the Brave Soul because he has many physical attacks. All his normal attacks use his guns, and he has the all-powerful Angelic Requiem at his disposal, which does physical damage to all enemies. Equip Jr. exclusively with tech attacks that do physical damage. Attacks such as Storm Waltz, Prelude to Battle, and Angelic Requiem are good, while Ether attacks such as Mystic Nocturne and Moonlit Serenade should be avoided. Angelic Requiem should be in his HI slot, if available. During battle, use a Hemlock on Jr. to hurt him badly, then immediately heal him for 150 to 300 points to keep him from dying too easily. Using Shion's Safety Level Ether is even better. Now that Jr. is thoroughly hurting, try attacking an enemy. Near the middle to end of the game, he can do over 500 to 700 damage with just his normal attacks, and anywhere from 700 to 1200 with his Tech attacks. As long as you can keep Jr. from taking too heavy a hit, or keep him protected with Safety Level, there should be few things that can stand up to him for long.
MOMO's first transformation
Go to the Cathedral Ship (inside the Gnosis). When you get to the stairs to go up (not the ladder), have MOMO as your lead character and search near the boxes. It should be there.
See Shion or MOMO in a swimsuit
When you are saving the people at the Kouki foundation, there is a chest in the hotel. When you get it, it will say "Swimsuit". You can equip it to Shion or MOMO. This allows their TP reward to increase by 25%. Also, when they are fighting they will be in a swimsuit. If you saw the intermission sequence where they are at the foundation's beach, you will see MOMO and Shion in a bathing suit. That is how they will appear as when they fight with the swimsuit equipped. Also, the same item can be won by completing Mission 4 of the Driller Game. A third and final swimsuit is to be found by defeating Great Joe. Note: Jr. and Chaos can also wear the swimsuit, and can be seen in swimming trunks.
See Shion without her coat
Immediate before the part where the Woglinde gets attacked, Shion goes to rest in her room. Notice that she takes off her coat. When the intermission sequence ends, you have the option to take a nap. Answer "No" and you can walk around as Shion without her coat.
Shion's Giant Robot Ethers
In the bottom of the Gear Shop in the Kukai Foundation, you can meet a strange professor who wants you to find parts so he can build a giant robot. Finding the six different parts, consisting of two arms, two legs, a torso, and a head will reward you with four different Ether attacks for Shion. These parts are located in the various Segment address rooms, which you find through exploring. The first attack is rewarded when you find both arms, and is called the Throni Blade. Next, you will find both legs which reward you with the Ether attack called the Dominion Tank. The head is the next item you can get, unlocking an attack called the Seraphim Bird. Finally, you will find the body which combines with all the other parts to create the summon of Erde Kaiser. This is the most powerful attack in the game, causing 9999 damage, but requires twelve Skills slots it makes it the only Ether that Shion can use.
Whenever you are viewing a previously watched scene, press Start then press Triangle. You will then skip the entire scene until you are in quest mode again. Pause game play and you will be prompted if you want to resume or skip the scene. This is useful when you have saved a game before a scene and get killed afterwards.
Moving quickly and silently
Tap R2 rapidly when walking around to can hover quickly without making a sound.
Hold L1 + L2 + R1 + R2 + Start + Select during game play.
You have to face Gargoyle in the Gnosis Cathedral Ship. The Gargoyle actually Commander Cherenkov. You need to have Shion, chaos, and KOS-MOS fight. Make sure that you have the upgraded frame and generator parts for Shion's and chaos's A.G.W.S. units. Equip both A.G.W.S. units with a sword since the Gargoyle and other Gnosis aren't good against close range attacks. Make sure everyone is at least level 18 or higher. When the battle starts, get into the A.G.W.S. units, and only attack the Gnosis on the right until it is dead. Why the Gnosis on the right? Because it can heal the Gargoyle 600 hp every turn. Then have KOS-MOS use med-kits on herself until she is fully healed. Finally attack the Gargoyle.
