The player explores the real world from a top-down perspective as Lan and enters cyberspace through connected devices. In cyberspace, MegaMan.EXE moves across a three-by-six combat grid, fights viruses, solves environmental puzzles, and searches for paths through themed areas.

Battles are real-time. MegaMan can move, fire his MegaBuster, and use a folder of selected Battle Chips. A Custom screen periodically pauses the action so the player can choose chips, while NaviCust programs, equipment, and version-specific powers expand MegaMan's abilities.

The story advances through school investigations, area exploration, boss battles, and liberation-style missions. New chips, upgrades, forms, and programs provide progression, while optional enemies and challenges encourage folder optimization.

Build folders around a small number of compatible chip codes so useful combinations appear consistently on the Custom screen. Keep reliable defensive options, such as AreaGrab or recovery chips, alongside your main damage plan.

Use MegaMan's movement to avoid attacks rather than trading damage. Learn enemy patterns, then punish openings with chips that hit across rows or lock down a panel.

Explore every story area after major events. Hidden paths, blue Mystery Data, shops, and optional bosses provide chips and upgrades that can make later liberation missions substantially easier.
