In Mega Man Star Force, players explore towns and interact with people in the real world while the action-packed battles take place in the virtual dimension. Enemy encounters take place on a three by five grid, where players use a portfolio of Battle Cards that each have distinct attributes and attack powers. As the story progresses, players will acquire additional cards and can build an arsenal that reflects their personal strategy. Players can also connect wirelessly via the Nintendo Wi-Fi connection with friends to create a "Brother Band" network, where they can share cards and status upgrades.
