Play MegaMan Battle Network 4 Blue Moon (U)(Rising Sun) Online

MegaMan Battle Network 4 Blue Moon came out on the Game Boy Advance in 2004, developed and published by Capcom. It was part of a busy era for the handheld, where many action RPGs blended real time and turn based systems in creative ways. This entry continued the series' hybrid approach, splitting gameplay between a top down overworld and strategic combat arenas.

You control Lan in the real world, talking to characters and advancing the plot, while MegaMan explores cyberspace in screen by screen segments. The main goal involves progressing through a series of net tournaments, battling other NetNavis and deleting viruses. Combat uses a grid based system where you select Battle Chips from a randomized hand, aiming attacks and dodging enemy patterns in real time. The game introduces Souls, temporary transformations that grant unique abilities, and features exclusive chips not found in the Red Sun version. Pacing can feel uneven due to repeated tournament structures, and some boss fights demand quick reflexes. Playing it feels like managing a fast paced, tactical duel where every chip choice matters.
