Hint: Forest Of Dysis: Rare elf:
The rare elf "Zero" is found in Forest Of Dysis (the stage with the forest) when in easy mode. Once you are in the inside part of the stage where you fight the statue that raises water and throws purple beams, destroy the statue. Afterwards, jump the pit and slide on the left side wall through a secret passage. Keep sliding down and on the way you should find the rare elf. If you keep sliding down, you will reach a secret area with lots of crystals and an extra life.

Hint: Crystal Caves: Secret area:
When you start, go up the hill and destroy two robots. Then, go down but watch out for the spikes at the bottom of the hill. Start going up the second hill. Jump on the ledge but do not jump over the ledge. Instead, slide down the wall on the right in the pit and keep holding it. You should go into a secret area that has a cyber-elf capsule and a life. Note: When you get out, you will need the light-blue armor. If you do not have it, you will fall into the spikes.

Hint: Sand Wilderness: Extra life:
First, talk to the Operator and transfer yourself to Sand Wilderness (the first area that you are in). There is an extra life hidden there. It is after the second mini-Boss, after the bird in its nest next to a gunman, but before the two birds in one nest. You will find it when you are there; it should be in an opening under the gunman.

Hint: Sand Wilderness: Not what it looks like:
In the Sand Wilderness (the desert area) there are mecha-vultures. They launch from what appears to be a nest, but it is actually the ruined remains of an enemy robot. [Screenshot]

Hint: Defeating Bosses:
For easy wins against most Bosses, charge the Z-Saber and attack the Boss. Keep hitting him and, with five or six hits, he will be destroyed.

Hint: Defeating Scorpion Hunter:
At the end of the starting stage, you will face a Scorpion. This arachnid will block your buster shots with his claw-shield, as well as launch it at you. Trying to avoid that projectile slows down the battle, but there is a way around it. When the Scorpion launches his claw-shield at you, attack it with your Saber. It should take two or three hits with the Proto Form active in Hard mode. You might receive some damage while doing this, depending on your timing. When the claw-shield is destroyed, the Boss is pretty much open to attacks. Just dash in and hack his head with your Saber, or shoot from a distance with your Buster (the Saber works faster). This will cut the battle down drastically. [Screenshot 1] [Screenshot 2]

Hint: Buster Shield:
Attach Buster Shot as your main weapon, and Sheild Boomerang as your sub-weapon. Enter attack mode B, then hold R and press B. Note: You can charge the Buster Shield.

Hint: Final mastery:
When battling the final Boss, try this strategy. When he rises slightly higher into the air, dash under him and use the Upward Slash technique, which requires the Fire Chip equipped and the "Tenshouzan" EX skill. Also, try using the Active Form, as it is the fastest form in the game. This lets you get in and out faster. This will do an excellent amount of damage, and is fairly safe if you know what you are doing.

Hint: Ultimate form moves:
You can have special moves when in ultimate form. Two of them are Down/Forward + B with the Saber equipped, and Down/Forward + B with the Buster equipped. The saber one uses the charged saber attack without charging; the same with the Buster.

Glitch: Misspelling:
When you defeat every Boss, X will appear and start talking about the Dark Elf. He explains that he is trying to keep her asleep and says "With my remaining power, I'm still TYING NOT WAKE her up...," instead of "With my remaining power, I'm still TRYING NOT TO wake her up..."

After defeating the four bosses on the monitors, there is a scene where Elpizo tells the members of the resistance to fire at Neo Arcadia. Ciel comes in with the Scientist and tells Elpizo to give them time (or something similar). Before Elpizo teleports, he says "Don't worry. We can work this OUR later", instead of "We can work this OUT later."

Glitch: Thunderball:
First, go to the stage "Power Room". Keep going through the level until you come across the pink floors. Above from the pink floor should be a blue ceiling. Blow it up with the bombs that fly around the level. Beneath the pink floor is an enemy that changes elements. First it shoots fire. Make sure you are the electric element when doing this. After it shoots a fireball, it will shoot a thunderball. Quickly jump into the hole in the wall and get to the top. The thunderball will split, and follow you, and become glitched.

Glitch: Chain Rod:
To do this, you must be in the Forest Of Dysis (the first forest level). After you defeat the wall mid Boss, go where the energy restore is found and continue up. You will see a stone block. Push it out with the Chain Rod. Then, go down. There will be a small opening to the left. Jump on top of the stone block and stand on the very edge. Jump, then use your Chain Rod down and do not let go. Quickly swing to the opening and continue to hold Left. You will start turning invisible then go through the wall and appear below. If this did not work, you were not on the edge.
