Mega Man Battle Network 3 walkthrough

Introduction
"The year is 200X. The world's machines are joined in a worldwide network. But there is a dark side to this convenience as well: Computer viruses, and an increase in NetCrime. The Virus Lab at Scilab... conducts ways of dealing with these viruses. One day... the students of ACDC School, in ACDC Town in DenCity, took a field trip to the Scilab's Virus Lab."

Main Characters:
Lan Hikari: A fifth-grader at ACDC School. Though his grades aren't too great, his virus busting skills are top-notch, defeating the WWW and the criminal netmafia Gospel. His Navi MegaMan.EXE was carved out of the memory of Lan's twin brother Hub, who died at an early age.

Mayl Sakurai: Lan's friend and classmate. Thoughout the series, she and her Navi, Roll.EXE, develop feelings for Lan and his Navi.

Dex Oyama: Another friend and a classmate of Lan. Arrogant and hardheaded, he is also academically troubled, but shows a loving side with his his little brother, Chisao. He and his Navi often have feelings for Mayl and her Navi, but is often turned down. His Navi GutsMan.EXE is shown to be very strong.

Yai Ayanokoji: Also Lan's classmate and friend, she is the daughter to very rich parents. She is also very smart, considering that she's too young for fifth grade. Though not seen in battle, her Navi Glyde.EXE is known to defend himself with rare and powerful chips.

Eugene Chaud: An Official NetBattler, and a rival to Lan. Though he has a cold attitude to Lan, he sometimes helps him when the going gets tough. His Navi ProtoMan.EXE is also extremely skilled.

Day 1
Talk to all the students and Miss Mari will tell everyone to jack in so press R and follow the tutorial if you don't already know. After the field trip talk to your friends and leave school and go to the playground. A man named Sunayama offers Lan and his friends the chance to battle live on television, and N1 preliminaries are being held in ACDC Square. Enter Lan's house, talk to your mom, enter your room, read Dex's e-mail and jack into your computer.

ACDC Area:
''A helpful tip to know is that some viruses have elemental weaknesses. When a virus is attacked by a chip they are weak against, or if it's on a certain type of panel, The damage dealt is double, and maybe quadrupled if both factors are included. The way elements affect each other in the game goes like this: (Aqua>Fire>Wood>Elec>repeat)''

There are also certain panels that can affect your attacks and the entire battlefield:
 * Cracked Panel: If you stand on a cracked panel and step off of it, the panel will break and cannot be stood on unless you have AirShoes.


 * Ice Panel: If the panel is on a middle row or column, Megaman and the enemy will slip and be pushed to the other side of it. Aqua Styles and Aqua viruses prevent slipping on these panels. Double damage occurs with Elec chips.


 * Lava Panel: Megaman and a non-Fire elemental virus will get damaged walking over these panels. Heat Styles and Fire viruses can walk over these panels without getting damaged. Double damage occurs with Aqua chips which also eliminate Lava Panels.

​To make things easier, these letters will represent the elements of viruses and chips:
 * Grass Panel: A normal panel to walk on, these panels recover HP one by one with Wood Styles and Wood viruses. Double damage occurs with Fire chips which also eliminate Grass Panels.
 * Sand Panel: These panels slow down Megaman as he walks over them, no matter what style. Tornado chips and PowerAttacks do double damage.
 * Metal Panel: These panels cannot be cracked.
 * Poison Panel: Megaman's HP and the virus' HP will drain one by one as long as they stand on it. Causes deletion when health drops to 0.
 * Holy Panel: Reduces the damage of enemy attacks to half while standing on them, which can also halve the damage of your attacks when used by viruses.
 * (X)- None
 * (A)- Aqua
 * (F)- Fire
 * (W)- Wood
 * (E)- Elec

Viruses Encountered:


 * (X)Mettaur: A helmet-wearing virus. Moves up and down, firing shockwaves down your row. In groups, one attacks, while the other remains stationary. Drops (X)Guard and (X)ShockWave chips.


 * (X)Canodumb: A stationary cannon virus. When Megaman lines up with the virus, a cursor goes down the row, then shoots if the cursor catches Megaman. Drops (X)Cannon chips.
 * (E)Eleball: A small, floating virus. Viruses like these that float can go over cracked panels without breaking them, and are not affected by special panels (except Poison and Holy). Moves diagonally, damaging Megaman if in their way. If Megaman faces them, they will stop and fire electric sparks on the surrounding panels. Drops (E)Plasma1 chips.
 * (X)Boomer: Another floating virus. Moving up and down, the boomerang it holds blocks against your shots and chips. When the boomerang circles the entire field, the Boomer becomes vulnerable to attack. Drops (W)Boomer1 chips.

Follow the arrows to ACDC 3, and look for a warp point on the lower level to go to ACDC Square. Talk to the Navi east of the warp point to enter round 1 of the N1 preliminaries. Round 1 is simple: The Navi asks you three true "O" or false "X" questions, and you have to give him the right answers by collecting X and O data scattered throughout ACDC and bringing it back to the Navi. Answer "YES!" to "Do you want to be the No. 1 NetBattler" to start the round. Here's the first question: Red means "Stop"! Look for the "O" data in ACDC 3, at a dead end past the cyber squirrel. Bring it back to the Navi for your second question: A ton of lead is heavier than a ton of feathers. Look for the "X" data in the plaza in ACDC 2. Bring it back to the Navi for your last question: Adding every number from 1 to 10 gives 54. Look for the "X" data all the way back to the beginning of ACDC 1 via your PC. Bring it back to the Navi to conclude round 1 of the N1 preliminaries. After a nice dinner, use the YaiCode that Glyde gave you back at ACDC Square to access Yai's PC in ACDC 2 and meet up with her. Talk to everyone to start the one-hour chat. After the chat, Dex realizes that he forgot his disk for a school assignment, but when we get to the front gate, we realize that it's locked, and the lock is somewhere on the Net. Go to ACDC 2 and go to the place where you found the "X" data. Press A in front of the key to unlock the school gate. Read Mayl's e-mail, jack out, and go inside the school. Go to your homeroom and check the third animal cage to obtain Dex's disk. When you almost exit the school, there are strange noises coming from the Teacher's Lounge. Go to the Teacher's Lounge and go inside the door. A voice on the other side talks about a strange object called a TetraCode. When you enter the Principal's office, the unknown person's Navi, FlashMan, uses Hypno Flash and hypnotizes Mayl, Dex, and Yai. Before FlashMan catches you, you flee the scene. Check the school to find where everyone's gone. Talk to Mayl in the first hallway and get a Roll chip. Enter the next door to find Yai in the next hallway and talk to her. Then go into your homeroom and talk to Dex. Lan realizes he needs something to block the light, so check the room next to you and check the top left desk for a Parasol. Go back to the Principal's Office and use the Parasol to block the Hypno Flash so you can jack into the Principal's PC.
 * (E)Bunny: A virus resembling well...a bunny! Jumps from panel to panel, firing electric rings down their rows. Causes paralysis, leaving Megaman open to other attacks. Drops (E)ZapRing1 chips.

Principal's PC:
Viruses Encountered: Inside the Principal's PC, your walk is cut short by three security doors. Talk to the program and he says you need "Keydata" to open the security doors, but the area is too dark to search for them. Using the hint "Cleaners1", go to the same room you found the Parasol in, and turn on the light switch so the Principal's PC is bright enough to search for Keydata. As the lights flicker on and off, so does mystery data in the area, and the three Keydatas are each hidden inside pieces of mystery data. Obtain KeydataA to unlock the first door to KeydataB, obtain KeydataB to unlock the second door to KeydataC, and obtain KeydataC to unlock the door to the next area. The next area is also dark, and you need three passwords to get to FlashMan. Go back to the Teacher's Lounge, and turn the light on over there to light up the next area.
