Mega Man Battle Network 4: Blue Moon

The game blends story exploration with grid-based battles. In combat, MegaMan.EXE moves within a six-panel field, dodging enemy attacks and firing Battle Chips drawn from a custom folder. Progress is driven by main story missions, network exploration, side requests, and a bracket-style tournament structure. Chip codes, elemental matchups, and folder composition all matter, and the Blue Moon version changes some exclusive encounters, rewards, and scenarios compared with Red Sun.

Build your folder around a few consistent chip codes so you can chain attacks reliably. Learn enemy patterns before committing to aggressive setups, and use movement to avoid wide-area attacks. Keep recovery and defense chips in reserve for boss fights, and take time to explore network areas for HP upgrades and useful subchips. Blue Moon exclusives can make certain encounters and rewards more efficient, so plan your route around the version's advantages.

Tips and tricks

• A folder with fewer chip codes is usually easier to use consistently in battle.
• Keep at least one strong recovery option for longer boss encounters.
• Use panels, barriers, and movement timing to avoid damage before counterattacking.
