Mega Man Battle Network Unlockables

Beat Skullman, Elecman, Woodman, Sharkman, Protoman, Fireman, Numberman, Gutsman, Iceman and Colorman over busting level 5 to receive their own battle chip with one of their most powerful attacks.

When you get to the Higsby guy from the school incident has a business as a chip salesman (in front of the gates of the school), go inside and save your game next to the chip trading machines (the ones that resemble candy or mini-toy dispensers in real stores). You can now freely trade 3 or 10 chips for another one, depending on which machine you use. If you do not get a chip you want, turn off the game, turn it back on, and resume from your save. Repeat the chip trade until you get the one you want, or get a rare one.

Place at the least three Navi chips, five Cannons, and twelve of your choice and you should get that chip.

To encounter Bass from the classic Mega Man games, get 174 battle chips in your library. This is all the chips except for the one he drops, which is the Life Aura. Then, go to Internet area 16 where the two men are standing almost parallel. Walk around (it may take a while) and sooner or later you will encounter Bass. Put all the Recover 300 chips you have in his folder, as he is very difficult.

After you beat the Ice Man, go to the Waterworks. In the back of the room in the northwest corner is a man next to a soda machine. Talk to him and he will say that the machine is broken, and for you to jack in to fix it. Do what he says and talk to the purple robot in the middle to face three viruses. Defeat them and jack out. Talk to the man and he will give you a Repair G chip.
