Mega Man Battle Network 3

MegaMan Battle Network 3, known as Battle Network Rockman.EXE 3 in Japan, takes place not long after MegaMan Battle Network 2. There are two versions: White (no subtitle in Japan) and Blue (Black in Japan). A NetNavi tournament called the N1 Grand Prix took place. Half of the game involved qualifying for the tournament.

Story
Months after the Netmafia Gospel tried to take over the world, Lan Hikari and friends return to their ordinary lives,until the crime organization World Three (WWW) started surfacing again. At the same time,a Netbattle tournament called the N1 Grand Prix was being held, in an attempt to find the strongest Netbattler in the Electopia,attracting people from neighboring countries into enterting.Lan and MegaMan manage to pass the prelimanary rounds,only after numourous attacks by the WWW in an effort to get the TetraCodes. Once Lan and MegaMan get into the N1 Grand Prix, the tournament was discovered as a set-up by WWW to intimidate the world about their return.

WWW had also revealed their plan to revive the monster Alpha (Proto in Japan) and take over the world. Lan and friends, with the help of Chaud Blaze(Eugene Chaud in Japan) had pieced together the WWW's plan after their attack on ACDC School,and then the Yoka Zoo,both hiding places of TetraCodes.Alpha was the original prototype of the internet. However, he went berserk and devoured any Navis and programs. The scientists were forced to seal Alpha to prevent further damage.

In addition to the TetraCodes, WWW had needed Bass in order to awaken Alpha. It was revealed that Dr. Wily, head of WWW, was moving behind-the-scenes in net mafia Gospel, and had put them to the task of creating a copy Bass specifically for the resurrection. This time, Wily didn't need a fake Bass because he tricked the true Bass into removing the final security measure. When Lan and MegaMan arrived, Alpha was awakened and after a battle with Bass, Alpha appears and devours Wily (who was in the net with a Pulse Transmission Program) and Bass, seeing that they started to fight Alpha. Once they destroyed Alpha,a door appeared, leading to a VisionBurst of SciLab,where Lan (also on the Net) and MegaMan met Tadashi Hikari,Lan and Hub's grandfather. Being only personality data,he was only able to give Lan and MegaMan an encoded letter to be delivered to Lan's father,and also remarking on how well Lan and Hub had become great friends and brothers,before the Vision Burst within Alpha collapses. Before being able to jack out,Alpha grabs Lan and MegaMan,until MegaMan sacrificed himself to save Lan.MegaMan was thought to be deleted,until Lan's father finally decoded the letter from his father,which contained MegaMan's backup data,and Tadashi Hikari's personality data.

Changes from previous versions
Once again, the game introduces a few changes to the folder building system. First, the Library has been split into 4 portions - Standard chips, Mega chips, Giga chips, and Program Advances. This allows for a more balanced folder whilst allowing for amazingly powerful chips to be used.

Standard chips are now limited to 4 copies per folder, and all Navi chips from the previous game are treated as Mega chips, along with some incredibly powerful chips. As you can only hold one copy of a Mega chip in the folder, this prevents the abuse of incredibly powerful chips like Full Custom, which was horribly exploited in the previous game, where it was allowed in 5's like every other chip. Giga chips are a new addition, giving way to really powerful chips like Balance or Navi Recycle. Only one Giga chip is allowed per folder.

The Navi Customizer (Navicust for short) is introduced in this game, too. Instead of receiving PowerUps which are used to permanently upgrade the Buster, the player now receives Navicust pieces that grant him different abilities, in addition to upgrading the Buster, like the ever-useful Undershirt. Some parts of the plot also require the use of certain parts, like Press or Black Mind. This game is the only version that uses Extra Codes and Colour compatibilities, seeing that after MegaMan loses Styles in the following game, the codes and compatibilities are of no use afterwards and are hence scrapped.

Styles now serve a different function too. Levelling up your style no longer improves the damage of your charged Buster, but instead grants you special Navicust pieces that can be used with the style. Some existing Styles are also given new innate abilities, like the Custom Style's ability to yield special chips when S-ranking viruses. Three new Styles are also introduced, with two of them being exclusive to either version. MegaMan now can only hold one Style, though.

Finishing off opponents while they are in the midst of attacking - also known as Countering - will give you Bug Frags. These are used in many areas - for trading, virus breeding, and for trading at the Bug Frag trader. This game also introduces the Number Lottery, where the player can input a certain number code to get an item. Often these items would range from subchips to rare items, unobtainable through any other means.

Trivia

 * The device that Cossak invented that allows living things to access the net bares a notable resemblance to the jack-in chairs from The Matrix trilogy, both in terms of function and design.
