See also: Mass Effect System Guide The Milky Way galaxy , a barred spiral galaxy containing between two and four hundred billion stars, is the setting for the events of Mass Effect. The player will explore many systems and planets as listed below in a bevy of story-driven missions and optional assignments across the mass relay network. The galaxy is navigable through the Galaxy Map on the SSV Normandy in Mass Effect , and the Normandy SR-2 in Mass Effect 2 and Mass Effect 3 .
