Defeating Aprokrimon
First, destroy the five spike balls on the posts around him, avoiding the fire shots and wind blow. Whenever five flying things come to attack, just block. Do not try to jump on the area that he is on, as you will get shocked. After the spike balls are destroyed, he will shoot a purple attack that follows you. You must run around trying to hit him without getting hit. Magic and a gun weapon work well; you do not have to walk up to him, but they do smaller damage. Physical attacks are more powerful, but you must risk getting close to him.
Defeating Mecha Rouge X
To defeat Mecha Rouge X's first form, keep hitting him. After a few hits he will transport to one of the outside circles and summon three Mecha Rouges and a light will appear somewhere on the field. If the three Mecha Rouges get to the light, they will transform into copies of Mecha Rouge X with the same health, and it will take the same amount of time to defeat one of those as Mecha Rouge X. The easiest way to defeat Mecha Rouge X is to defeat only two copies. After that, weaken the third until you think he is defeated. Then, weaken the original to that point where it will require one hit to defeat him. Finish the last copy and defeat Mecha Rouge X's first form. You must now walk into the portal to fight Mecha Rouge X's second (cocoon) form. If done correctly, this form will be very easy to defeat. Hit the bottom of him. After a few hits he will generate purple rings around where you hit him. Move to the edge of the level. If you touch the purple from the purple rings you will get poisoned. Two things will come out of Mecha Rouge X, and there will be spotlights from bottom of them. Do not get under them or you will be stuck in that location and they will send out two spinning tops that will damage you. Just keep hitting the spot when there are not purple rings. Hit him as much as possible or he will regain health. Once you defeat him, go in the portal and get ready for the final fight with Mecha Ultimate X. Just stay under him and keep attacking to defeat him.
Dorumon
Reach level 16 with Agumon.
Double Axe description
The game states that Double Axe (all types) is a bash skill weapon. However, when you use it you will gain the blunt skill.
Easy experience
In single player mode, repeat the tutorial about fifteen times, then go to Death Valley. Once there, follow a path and fight some Goburimon; do not go across the bridge. Follow the path up and fight the Goburimon. They will give 10 experience points each. Break, then get the Gate Chip, use it, and repeat. Additionally, go to Death Valley, then to the Fortress. When you are inside the guard room, defeat everyone for 32 experience points per kill. After all the doors open, go outside and enter the fortress again. This must be done two or three times to reach the next level.
Easy tech ups
After you have unlocked the "Fortress" in Death Valley, whenever you need to equip a new weapon that is too high in tech points, just return to the Fortress and fight up and down the tower multiple times. You will receive between 10 to 60 tech ups in one revolution.

Get 1 HP for side quests
To get a Digivolution by having to end a side quest with 1 HP remaining, go to the Goblin level (this stage is the easiest). Make sure you have a Gate Disc with you. Fight and go to the area after the rolling barrels. When you get there and see the area where you must jump from the rock things to get to the other side, just fall. You will automatically be revived with 1 HP. Then, use the Gate Disc and return to the D.G.S. base. After your return with 1 HP, save the game. Next, go to the desired side quest that requires having 1 HP remaining to get the Digivolution. Note: While on the side quest, make sure you do not get hit by any enemies; this requires extreme practice and skill.
To get a Digivolution by having to end a side quest with 1 HP remaining in Card Retrieve on Hard mode, use the following trick. At the end there is a sand trap that will suck you in if you get too close to it. First, destroy all the enemies that can get in your way. Next, jump into the sand trap. You will be revived with 1 HP remaining. Note: When facing the master of the side quest, try to use MP type attacks or a gun type weapon.
