Play Megaman Battle Network 4 Blue Moon Online
Explore the real world and cyberspace as Lan and Megaman, battling viruses and other Navis while strategically using Battle Chips in real-time combat.

Megaman Battle Network 4 Blue Moon came out on the Game Boy Advance in 2003, developed by Capcom. It was part of a wave of action RPGs that really made the most of the handheld's hardware, blending real time combat with strategic planning in a way that felt fresh at the time.
You control Lan and his NetNavi Megaman, exploring both the real world and the cyber network, fighting viruses and other Navis to stop a new global threat. The core of the game is its hybrid battle system: you move on a grid in real time while selecting Battle Chips from a randomized folder to attack, dodge, or set traps. The game is structured around tournament arcs that you replay multiple times to unlock new areas, which can feel repetitive, but the constant need to adapt your chip folder and timing keeps the combat engaging. It feels like solving a fast, fluid puzzle with every encounter.
