Koprulu Sector - Antiga Prime

Antiga Prime was a colony of the Terran Confederacy during the events of the first game; however, the colonists had become disillusioned by the Confederacy, and with help from the Sons of Korhal initiated a rebellion. Lieutenant Sarah Kerrigan and Marshall Jim Raynor succeeded in destroying Confederate forces garrisoning the colony and established a base for the Sons of Korhal.

When a large Confederate attack force landed near their base, the rebel leader Arcturus Mengsk ordered a psi emitter be used to lure the Zerg into attacking the Confederates. Raynor and Kerrigan objected to this plan, but were overruled. The ploy succeeded, and as the Zerg swarmed over the Confederates — and subsequently the entire planet — the rebels escaped. The Protoss fleet led by Executor Tassadar later arrived and incinerated all life on the world.
