Synopsis of Halo: The Flood

Like the prequel of this book, Halo: The Flood is made of six sections.

Before you read on to learn what happened in each section, be warned that there will be spoilers ahead.

Section I, II, and III

Halo: The Flood begins with a United Nations Space Command spaceship leaving slipspace, retreating from Reach. The crew of Pillar of Autumn encounters a gigantic ring orbiting around a gas planet. This ring is known as Installation 04 or Alpha Halo.

A group of Covenant ships notice Pillar of Autumn but stop themselves from firing, fearing the potential risk of damaging the ring. The crew of Pillar of Autumn take advantage of this hesitation, destroying four Covenant spaceships. Meanwhile, the crew of Pillar of Autumn is trying to wake up the last Spartan-II, the Master Chief.

Their efforts are in vain. The Covenant manage to board the Pillar of Autumn, so its crew finds itself with no other option other than abandon the spaceship. Master Chief remains behind, for the AI system known as Cortana has too much information about the humans.

Master Chief eventually lands on the surface of Halo, the ring, where humans. are preparing retaliation. Pillar of Autumn deteriorates when entering Halo’s atmosphere.

Master Chief helps rescue some Marines. Together, they board another ship, from which they manage to rescue Captain Keyes. He tells them that he has realized that the Covenant believe Halo to be a weapon of great power, which is why he tasks the Master Chief to find the control room of Halo before the Covenant.

Section IV and V

As tasked, the super soldier Master Chief and the AI system Cortana succeed in finding the control room of Halo. They learn that Halo isn’t a weapon, and Cortana asks for Captain Keyes.

Master Chief goes search for the captain, but the former soon discovers that the latter was attacked and killed.

Out of nowhere, Master Chief is teleported by an AI that lives in Halo, named 343 Guilty Spark. It explains that the creatures abound are called Flood, and it’s a reproduce that contamines the host with the goal of reproducing more of itself. The AI asks the Master Chief for his help.

While this is happening, the Covenant army is attacking Halo, precisely where Master Chief stood just minutes ago. The United Nations Space Command fight back the Covenant forces, but an attack by the Flood stops them on their tracks.

When Master Chief is helping 343 Guilty Spark, the AI system Cortana stops him. It explains that Halo will kill all sentient life in the galaxy. To stop Guilty Spark, Master Chief and Cortana team up to destroy Halo before it’s too late.

Section VI

As Cortana and Master Chief tries to destroy Halo, 343 Guilty Spark and his robots try to stop them.

A countdown to the explosion has begun.

Master Chief and Cortana manage to escape Halo just in time before the explosion. Cortana is happy with the result, but Master Chief is not satisfied. He explains how the Covenant are still everywhere, risking planet Earth’s very existence.
