X's Ultimate Armor
First, get the Tianna Key for the the locked door in the Tianna Camp. Then, go to the locked door and open it. Inside you will fight a Boss that is accompanied by two Belladonnas. Defeat them, and after the fight break the red crystal to get X's Ultimate Armor Hyper Mode.
Lagrano Ruins Key.
To get the Lagrano Ruins Key, you need to use the Deployment Center. Keep deploying your robots until they can find the key. After a few times, you will see it listed on the right-hand side of the screen when you check on the returned robots. After going through the door in Largano Ruins, you will find a secret item/force metal/weapon shop.
Absolute Zero Hyper mode.
First, complete Chapter 8. Then, repeatedly deploy well-chosen units to the Melda Ore Plant in order to gain the Melda Key. Once you gain the key, go to the Melda Ore Plant and open the previously locked door (once you teleport there, go inside the plant and enter the locked door instead of entering the first elevator). Continue through the new area until you encounter a duck-like enemy. Defeat him and break the purple crystal behind him to gain the Absolute Zero Hyper mode. It should not be too difficult to defeat the enemy -- just continue to use X's and Zero's current Hyper Mode and Action Triggers and make sure you do not attack him with an element he is currently absorbing (a message will appear at the top of the screen whenever his absorbing element changes). Defeating this enemy is a lot easier than defeating the enemy which guards X's Second Hyper Mode.
Defeating Preon Nurse
Find a Preon Nurse in any unit. Destroy all enemies except the nurse. When the nurse is the last one remaining, steal its Reboot and Tank Energy 10. While you wait for its turn, keep using Zenny+ attacks on it. After the first turn of the nurse, it will say that it surrenders will use All Life 25 on your party. Then, destroy the nurse in order to get the Zenny bonus that you put on it before it attacks again. If you do not destroy it after it heals you, it will use an attack called "Then Thanks" and run away, giving you nothing.
