Play MegaMan Battle Network 4 - Blue Moon (EU) Online
In MegaMan Battle Network 4 - Blue Moon, you jack into networks, collect battle chips, and engage in real-time battles against viruses and other players.

MegaMan Battle Network 4: Blue Moon came out on the Game Boy Advance in 2004, developed by Capcom. It was part of a series that blended action and RPG elements during a time when handheld games were really starting to explore deeper mechanics and interconnected worlds. This version, Blue Moon, offered a slightly different set of exclusive Navis and chips compared to its counterpart, Red Sun, giving players another angle on the same core narrative.
You control Lan and his NetNavi MegaMan, navigating both the real world and the cyber network in a mix of exploration and combat. Your main goal involves participating in a global NetBattling tournament, which pushes you to strengthen MegaMan and uncover a deeper conspiracy. The gameplay splits between talking to characters and solving simple puzzles on the overworld map, then diving into network areas where you engage in fast, tactical battles using a customizable folder of Battle Chips. These real-time fights happen on a grid, requiring quick positioning and smart chip selection to delete viruses or face rival Navis. The pacing can feel uneven due to the tournament structure and some repetition, but building a powerful chip library and executing combos stays satisfying. It feels strategic and responsive, especially when you pull off a well-timed Program Advance.
