Mega Man Battle Network Legacy Collection gathers the action-RPG spin-off series in one package, letting players relive its unique blend of network-hacking adventure and grid-based battle system. The story follows a boy and his NetNavi battling viruses across a digitized world.

Players collect battle chips, customize their NetNavi's loadout, and fight through grid-based encounters across the collected games. Its distinct fusion of RPG and card-battle mechanics sets the series apart from mainline Mega Man games.
