The seventh spin-off series, Mega Man Star Force (aka Shooting Star Rockman in Japan) was set 200 years into the future, along the Network timeline during 220X. Players took control of Geo Stelar in a tactical role-playing quest to protect the world’s satellite network from everyday viruses and aliens of Planet FM. The series tweaked many of the systems introduced in Mega Man Battle Network and capitalized on the wireless functionality of the Nintendo DS, making it possible to trade Battle Cards and challenge a friend’s Mega Man in a 3x5 grid-based combat. Multiple versions of the games were released, each granting Mega Man a unique transformation.
