An extremely long-ranged missile launcher unit was being considered for the terran faction over the course of development for StarCraft II: Heart of the Swarm. Produced from the factory, the rationale behind the unit was to provide a new dynamic in terran vs. terran multiplayer games, in order to make it easier for players to break siege tank lines more easily.
