In the Mirror Universe Event, a group of players faces four Terran battle groups occupying a Federation starbase. With the help of four Surveillance Satellites an additional battle group can be weakened. With the defeat of the enemy vessels, the Terran flagship I.S.S. Stadi comes through a portal from the Mirror Universe. With the destruction of the Stadi, the latest Terran invasion is stalled.
