Mega Man Battle Network plunges the Blue Bomber into a virtual world, where he must battle computer viruses.

With a premise strongly reminiscent of '80s sci-fi movie Tron, Battle Network has you play as two characters. As school boy Lan, you live, go to school and visit friends' houses in ACDC Town. Trouble is brewing in this seemingly quiet 'burb, though. It seems that a sinister criminal outfit called "WWW" is infecting computer networks in order to take over the world.

Like his classmates, Lan has a Personal information Terminal (PET) - in his case, Mega Man.EXE - that moves through Cyber World. By jacking into computer networks and smart devices, Lan unleashes Mega Man to explore and battle computer viruses.
