Defenders of the Galaxy is a three-player scenario map for StarCraft.
A Galactic Defender and various Galactic Heroes defend each player's nexus from terran and zerg Galactic Dominators. The player begins with an arbiter and two dragoons. To obtain Galactic Heroes a player must move their arbiter to the protoss shuttle, terran dropship, or the zerg overlord. The heroes include the scout, Tassadar, Sarah Kerrigan, and a science vessel. Using these units, the player must defend their nexus from invading forces. The longer one lasts, the more points they receive. The player with the most points wins.
