Tips

An easy way to beat BassOmega

For this to work you will need:

Chips:
  1. WoodPower
  2. AreaGrab
  3. Any Wood chip to unite with

Navi Cust Programs:
  1. UnderShirt
  2. SuperArmor
  3. Collect

What you do is use WoodPower as your present chip to put grass panels on the square in front of you and in Bass's entire front row. Then, one you have AreaGrab, unite with WoodSoul, steal Bass's front row and stand on it. Using WoodSouls Twister you can deal 120 damage to him about every 7 seconds. After the battle you busting level will probably be 5. Don't worry! Collect will give you Delta Ray Edge.

Beating "Duo"

In order to beat the menace Duo you need to be fully loaded with program advances. It is strongly suggested that you have all three Gunsols. Also GunsolEx. The only spot you can hit him is in the row that his health his in.

If he is shooting the disability laser strongly try to dodge it. It can disable your customizer programs (but luckly not any HP+programs). Pack your custimizer with HP+500's so you can maximize your health.

Dark Chips

Do 800 damage quickly without dark chips

To do this, you'll need a few things. You'll need:
1. Aqua Soul(Blue Moon only)
2. A weak aqua chip to unite with.(bubbler will do)
3. Geyser chip
4. Area grab chip
5. Crack out/Dubl Crack/Tripl Crack chip
6. Full Synchro mode(Megaman has a purple circle around him in battle.

1st, you need to unite with aqua soul. Then you need to get a counter hit on the enemy before the 3 turns are up to get full syncrho mode. Then, you use area grab to get more room. Come up to the 1st row and use crakout on the middle row. Go back 3 spaces and, if you have geyser as your next chip, press and hold a to charge it up until you glow. Then move back 3 spaces and through the geyser.(you can't charge up geyser unless you have aqua soul on)

Fighting Bass

Unlike other games in the series, Bass is not part of the storyline. However, you must fight him before you can reach Black Earth. To reach him, you must have the S-ID (collect all 150 standard chips), and you must have all 6 soul unisons. To face him, go to the farthest corner of Undernet 5. There is a path that leads to a path below Forte.

Get Rid Of Darksoul

If you use too many darkchips, you will eventualy turn evil, but ( this is proboally so obvious ) but if you turn evil all you have to do is go to a place with low level viruses like the ADCD area 1, and equip your folder with chips like cannons, swords, and other chips that won't be affectied by dksoul, and start fighting enemys and eventually you will go back to normal.

Tip about Sword Soul, sword chips and Darkchips

You can get Sword Soul after you beat Protoman, unite with his soul needs a sword-type chip
Press and hold Button A can jump two spaces forward and use the sword chip with x2 damage
Press and hold Button B would activate chip "Wide Sword", 80 damage, attack the role in front of you, can cause counter

So, basicly, sword soul is pretty neat; now about the sword chips

Sword chips are very powerful indeed, but their attack range is usually very short, so you'll need many "AreaGrab" chips in your folder, letter S is great, * is even better, if you can get enough...
"Life Sword" is a great P.A., use it as frequently as you can, it has 400 damage, and a wide attacking range; team it up with an "AreaGrab", you can delate all viruses in a single hit if you are good enough
There are four ways to emerge "Life Sword"
ShortSword E
Wide Sword E
Long Sword E

ShortSword L
Wide Sword L
Long Sword L

ShortSword S
Wide Sword S
Long Sword S

ShortSword S
Wide Blade S
Long Blade S

I reconmande the ones uses letter S, once you get sword soul, you wouldn't want to try the one with Blade, because "Life Sword" is no longer a sword chip, you can't power it up using sword soul's ability, but you can power them up one by one, (80+130+130)x2=680, far better than "Life Sword", still, "Life Sword" is usefull in other ways

When using the chip "Varies Sword", hold Button A and you'll have a short period of time to enter the code, try it yourself
"NeoVaries Sword" can be used the same way, but how to use different attacks are not same, I introduce two ways:
down,right,up: X cut, the center is the space infront of you, that space takes doubled damage
left,right,left,right,Button B: Sword Wave, extremely strong, practice this well and you'll get triple delate at all times
When united with sword soul, "Varies Sword" and "NeoVaries Sword" won't work; so, don't waste your time trying

Another Tip, about Darkchips:
(first you have to finished Shademan with dark sword and get Junk Soul)
make megaman mad(HP becomes red), you'll see two dark chips in your folder, choose them, but don't use them, unless you wanna lose HP
The next turn, unite with Junk Soul, dodge all of enermies' attacks until custom is ready
Open custom, the dark chips you chose came back! Now you can use them without losing HP or become evil! And Junk Soul Recycles it many times, I think that many dark chips should be enough for any viruses... Maybe even Duo...

Then it will bring Life Sword and you can use it once in that battle unless you have more of the above.

WoodMan quest & SearchMan quest

If you are good at virus battles and never get deleted, then when you are doing the WoodMan & SearchMan quests, don't worry if you keep getting hit by their attacks, because if you have 1hp left then, their attacks won't do any damage. Hope this helps!
