Hidden Missions

Blizzard Entertainment created twelve Terran missions for StarCraft Episode I. However, Blizzard later decided to remove two of the missions, since they wanted each episode to have ten missions. These missions are hidden on older StarCraft installation CDs.

As they have been disabled, they are not generally considered canon for the StarCraft universe.

Biting the Bullet
In Biting the Bullet, which occurs after The Trump Card (in which the psi-emitter was activated), the Zerg on Antiga Prime are spreading, killing the civilians in the process.

Jim Raynor wants to rescue them by attacking the Zerg Hive Clusters, but General Edmund Duke says that's a foolish tactic, as the Zerg heavily outnumber the Sons of Korhal. Raynor calls him a coward, while Sarah Kerrigan tries to settle the argument.

Mengsk agrees with Raynor's tactics, and authorizes a Sons of Korhal attack on the Zerg, led by Duke and Raynor. While initially successful, destroying a Hive Cluster, the Zerg send a wave of reinforcements that Duke says they can't handle.

After barely fighting them off, they detect Protoss vessels in the vicinity. Raynor says they "play hardball", but the Protoss Executor, Tassadar, offers an alliance. He has witnessed their struggle against the Zerg. His fleet will cooperate with these Terrans to fight the Zerg.

Together, they destroy the other Hive Cluster and defeat the Zerg. The Sons of Korhal then abandon the planet, taking as many civilians as possible, before the Zerg overwhelm Antiga Prime and are then sterilized by the Protoss.

Trivia
General Edmund Duke commands the battle from his Siege Tank. This unit never makes an appearance in the official game, but is "rescued" for use in StarCraft: Loomings. The unit is available in the map editor.

Operation Silent Scream
The next mission takes place right after The Big Push. If it had been included, the psi-emitters would not have been activated at the end of that mission.

Arcturus Mengsk calls a meeting onboard his command ship, the Hyperion, in orbit over Tarsonis. He begins with a pep talk, saying the Terran Confederacy is about to fall. He orders his commander, former Magistrate of Mar Sara, to attack the city of New Gettysburg.

Lieutenant Sarah Kerrigan complains that this wasn't what they discussed. Even if they capture it, they won't be able to hold the area against the might of the Terran Confederacy.

However, General Edmund Duke says he will put down any attempted counter-strike. He refuses to tell Jim Raynor just what he is planning, however.

The raid involves an attack on Terran Confederacy infrastructure on the surface of Tarsonis. Sarah Kerrigan and Jim Raynor are there, leading the charge.

The war factories of Delta Squadron, Nova Squadron and Omega Squadron are all destroyed in a daring raid directed by Edmund Duke. During the raid, reinforcements are sent by General Duke at several points on the map.

Although the Sons of Korhal managed to cripple the Confederacy's ability to make war, they could not hold the area. This is when General Edmund Duke sprang his surprise.

He had secured the psi-emitters and they were now on-line. Sarah Kerrigan was outraged, and wanted to know who authorized their use. Arcturus Mengsk admitted that he authorized them, and overrides her protests, along with those of Jim Raynor.

This may have been when Nova Squadron made its escape on Nova Station.

Trivia
New Gettysburg is the name of one of Tarsonis' space platforms. It is not known if both the city and station bore the name, or if Blizzard liked the name enough to "rescue" it after Operation Silent Scream was removed.

Arcturus Mengsk's transmission comes from the battlecruiser accompanying the attack force, suggesting he was actually on the front lines. However, Blizzard Entertainment had not completed creating a unit for him. His unfinished unit, available in the Emerald Patch, is called The Leviathan. If Mengsk took residence on a new battlecruiser, this could explain how Jim Raynor was able to easily acquire the Hyperion for himself.

Arcturus Mengsk is never again seen on this battlecruiser, preferring to ride in the Norad III when his empire is conquered by the United Earth Directorate.

Once this map is beaten, the end transmission has the same exact lines as the previous map The Big Push.

This mission is featured in part of StarCraft: Liberty's Crusade.
