One month has passed since the battle ended with the Dark Chip Syndicate for the earth's existence.

Now back under the new name "Nebula", this evil organization is attempting to take complete control over the global internet.

Now players must team up with other cyber heroes to liberate the Nebula-controlled areas of the internet and stop this malevolent organization from taking hold.

The "Soul Unison" system returns, allowing players to utilize the special abilities from allies and defeated enemies encountered in the game, enabling Megaman to use their powers during battle.

Furthermore, the tempting "Dark Chip" will re-emerge.

Using the new "Chaos Union" system, players can fuse this attractive chip with an ally's 'soul' allowing them to control the power of the darkness.
