After winning we get a trophy and the elevator stops working. We have to jack back into the battling terminal. After the cutscene we fight Gutsman or Aquaman (based on the game version). After that we can go to the airport.

We get access to the 10-chip trader in the Colosseum.

Upon arriving in Netopia, you'll get an email to go to the riverside to meet a local representative. He is just to the left from where you get to the area. After talking to everybody in the area you have to go back to talk to him again.

You'll meet an old man who'll force you into a battle with some viruses.
You can also haggle the women to sell you chocolates for 250 zenny.
After that we get kidnapped... again.

If you go examine the statue at the corner of your room, you'll notice that there's a jack-in for it. Once you are inside the Net, talk to the program and you'll get the Hotel P-Code. Now head out the warp into Netopia Area.

Go left and up the ramp to get KeyDataA.

When you come down the ramp head even more left to get KeyDataD.
Now go down from where you enterred the P-code and left and down again forr KeyDataC.
And when you go right you will find KeyDataB.

Now jack out to trigger the next cutscene.

Now it's a new day. Go to the Colosseum and interact will the face on the wall.

Because LAN gave a compliment to Pauline he invites us to the Water Festival in his village. There is only one place to jack in so go to the totem and fight the navi to get the P-code. He'll then throw you into a test of three netbattles.

Walk around to the big open area.
Now go to Netopia Net to get to Sharo Net to pick up the WaterGod Idol. The screenshot is from the other side. You must go through Netopia.
Then return to the big open area and talk to the navi standing there. After the cutscene you get LionKey. Jack back into Netfrica and use the key on the blue gate on the other side of the large area.
The LionKey will unlock the first door. For the second door, you'll have to answer some questions to unlock it. In order of questions, choose 4, then 2, 60, green, and lastly 22. For the last door, you'll have to go through some battles.


Pick up the RecoverDrop, then jack out and go to the WaterGod statue. The next part is a maze. I recomment you look at Mega Man Battle Network 4: Red Sun - Water God Computer Map by danstu[gamefaqs.gamespot.com] or use my graph below. The correct path is:

comp1 → comp5 → comp3 → comp2 → comp10 → comp8 → comp16

If the comp color is red it means you need to netbattle. Comp16 has 5 battles that start when you interact with the statue. The graph should make sense.


Comp5

Comp8

Water God

Now after clearing the battles go delete the hell navi.

In Sharo, head up to the Space Center that's at the top of Sharo. Talk to the man in the lobby. He will give Lan the opportunity to join Raika in his mission, if he can beat some viruses.

The man will give Lan a CopyKey, which will get him to the hideout in UnderNet6. Now, we'll need the C-Slider to proceed along with the mission. To obtain the C-Slider, look up the C-Slider in the miscalanious tab of this guide. Then go to the Sharo Area from Netfrica Net and continue to UnderNet1.

Now you have to go to UnderNet6 while being snipped by SearchMan. It's not that hard to get to UnderNet6. When there open the blue gate and delete the heelNavi.

Jack in the hotel and go up the ramp.
Now go to the airport and to Sharo.
Talk to the guy on the floor and he will tell you that you need fire battle chips. The ones you need are:

• FlameLine F (common encounter)
  
• BlackBomb Z (Purple mystery data behind the C-Slider Navi)
  
• HeatBreath K (Netopia Net Navi Merchant)
  
• HeatShot C (Higsby's chip order)

Go to any snow pile. MegaMan will tell you that you need a shove. Then go to the first house.

Beware that the antennas have mystery data that can only be obtained in this scenario.

Antenna 1 RegUp1
Antenna 2 HP Memory
Antenna 3 BugBomb G
Antenna 4 Battery program

The viruses are not hard, because they are mostly MettEX. So I don't list them in detail. After using the torch in everry Antenna we can go delete ColdMan.

The green navi and his operator want us to play soccer called FootBomb.
Go to to your guest room, jack into the statue, and then go to Netopia Net. Next to the gate to netfrica there is a brown navi. He needs a Guard1 A chip.
Now go into the statue next to the river and talk to the green navi. You have to just kick the bomb into the goal and that's it. After that go to Netfrica Net and talk to the green navi again.
Now jack into the status in front of the colosseum and talk to the navi again.
Now go delete him in the tournament.

Go take the airplaine to Netfrica and talk to the man in the village, then jack into the totem. Talk to the navi next to the warp to get the netcode. Then go up the ramp.
Now go to the first dummy. A + Left is block. All others are the arrow on screen + A.
Now go back to kendoMan. After that we can go start our fight. But Mr. Famous won't show up so we have to go to Netfrica and jack into the Lion statue in the corner.
Now destroy the purple transmitters. Also don't forget to pick up the regular memory in the corner.

After the cutscene we delete a green navi. Go to the hotel and jack into the Netopia Net.
Talk to the orange navi. Then go talk to Raoul in front of the Colosseum.
He explains the situation. Then we have to get The BraveryMark, StrengthMark, WisdomMark, and
KindnessMark from the net.
Now go to Yumland.
Now open the curse door and pick up the doll.
Now talk to Thunderman in Netopia area after that go delete him in the Colosseum.

This scenario needs the C-slider.
We go to the undernet from Netfrica -> Sharo -> Undernet.
Now we get to the first gate.
Now we need to get the key. It's a bit back.
We get to undernet 2 where we need the Blue and the Green key.
The Blue key is all around and can be seen from the gate.
The Green key is next to the conveyor belt
Now we need 3 keys
[/previewimgThe Yellow key is on the right side of the map
The White key is to the left.
Now go from Undernet 6 to Undernet 5. And after the cutscene you can go delete protoman.

Talk to the navi in Yumland and open the gate to start the cutscene.
After that talk to megaman by pressing L a bunch of times. Then go back to the junk pile. Now delete te viruses. After the cutscene go to Yumland.


Go to Yumland and talk to the man in front of the mall statue, then talk to the woman in then corner. Then jack into the big Buddha statue and talk to the green program. Then go delete JunkMan.

After we win we go to NAXA.

We get a few cutscenes. After that we have to go around the world and fix the internet. Go to every area and destory the jammer that is located between maps. I'm not gonna list them all, because they are easy to spot and in a logical location. You have to go to:

• Sharo Net
  
• Netfrica
  
• Yumland

After that go to Netopia Area and talk to the navi on the picture.

Now go to Town Area2 and open the upper door on the lower floor.
Just go on the path till you reach the heel navi.
Now go to NAXA Lobby and talk to the guy in center. After that we can jack into the Meteor.
Watch out for black holes. They reset the area. Spam A and B to avoid them.
This section is kinda boring to explain. So I recommend you look at the map instead.
Megaman BN4 maps [www.interordi.com] Just touch them in order.

When you reach MeteorComp4 you will delete LaserMan. Then a DarkSoul version of yourself (same chips and HP etc.) and finally Duo.


Now the game will offer us the option to start the second run or continue the first. Continue the first if you missed any collectables.

Lotto numbers, C-slider, navi locations etc.

The Number Trader appears inside Higsby's when Castillo becomes available. You can use the Lotto numbers at any time. I perfer to get it over with as fast as posible. There are a total of 32 Lotto Numbers.

To unlock the C-slider you need to buy 3 parts on the net and have access to Netfrica Area.

BoardPart: In Town Area2 for 2000 zenny in the lower part.

JetPart: In Park Area1 go past the broken path, on the right side. From here go to Town Area3. In here, take the far right side of the fork and talk to the Green Navi. He'll offer you the JetParts for 3000 zenny.

WingPart: From ACDC 2 head to Yumland area, take the green path until you hit the corner with a yellow path lacing ownwards under a high walkway. Under the walkway, there will be a purple Navi who will sell you the WingPart for 4000 zenny.


In Sharo (from NetFrica), take the two belts going upwards, and head down the ramp. Talk to the Navi there, and he'll warn you that the narrow path leads to the Undernet. He then tells you that to pass, you'll need to find the Slide Master that's around the area.


Open the blue gate to the left in Sharo with 500 zenny. Go up and talk to the girl Navi. Her grandpa was the Slide Master. Hand over the parts, and she'll make the C-Slider that you need.
