Partie 1
<toggledisplay showtext="Version originale" hidetext=Masquer> The first invasion efforts and the Spartans' early victory.
Although Halo 3: ODST begins on October 20, 2552, its story really starts much earlier. Some time before the Covenant's occupation of Earth, the Prophet of Truth managed to discover the location of humanity's home world—a distant, backwater planet known as Earth. Seeing this as an opportunity to obliterate the last stronghold of his enemy, he went quickly to work.
Truth swiftly commissioned a massive fleet and privately summoned over five hundred warships to a command-and-control station called Unyielding Hierophant. When UNSC forces uncovered this plot during the events of Halo: First Strike, they initiated a covert assault of the station. Led by the Master Chief, a strike team of SPARTAN-II super-soldiers infiltrated Unyielding Hierophant and destroyed it, along with the vast majority of ships in its charge.
The station's ultimate goal and its eventual destruction were suppressed by the Prophet of Truth—Unyielding Hierophant's original purpose has since remained a closely guarded secret. </toggledisplay>
Partie 2
<toggledisplay showtext="Version originale" hidetext=Masquer> The Prophet of Regret's inadequate invasion force collapses.
Shortly after the station was destroyed, the Prophet of Regret also discovered something significant about the planet Earth—it hid an ancient Forerunner artifact of great implication. Buried below its surface was an ancient machine capable of generating a portal to a remote facility known as the Ark—the place where the Covenant could finally initiate their Great Journey. Yet Regret remained oblivious to the fact that the planet was humanity's home.
Anxious to exploit the artifact's power, Regret led a meager detachment of fifteen ships to Earth. After Truth learned of Regret's brash and foolhardy move, he quickly sent an enormous support and excavation fleet to Earth.
When Regret arrived near the planet on October 20, 2552, the Prophet was so intoxicated by religious fervor and the untapped potential of the Forerunner machine, he ignored the strength of Earth's defenses and sped toward the planet's surface. At the coastal city of New Mombasa, he ferried down troops in search of this machine but was soon forced to retreat when UNSC forces converged on his position.
While Regret was unable to locate the Ark's gateway portal, he managed to divine the location of a new Forerunner ringworld—Delta Halo—to which he would escape, ultimately meeting his own end during the events of Halo 2. </toggledisplay>
Partie 3
<toggledisplay showtext="Version originale" hidetext=Masquer> Truth's plan and the Covenant's occupation of Earth.
The city of New Mombasa was nearly destroyed by Regret's venture into Slipspace, and the Covenant forces which remained above the planet were now without a leader. Although the Elite commanders continued to engage the human forces in space, the Prophet of Truth had moved his own plans forward—machinations which would forever change the Covenant.
Well before even that day, Truth had begun to doubt the reliability and loyalty of the Elites, who were, at that time, the heart and head of the Covenant military. Though Regret's ineffective invasion of the human home world was problematic, Truth would use it to his advantage. Not only was the support and excavation fleet he had already sent to Earth commanded exclusively by Brutes, but he would also leverage the abandoned Brutes who had served in Regret's initial fleet.
Aboard those vessels, the Brutes were ready and willing to unflinchingly obey the Prophet's commands. Once Truth gave the word, these soldiers forcefully overthrew the Elites and assumed complete control of the battle above Earth. Upon further orders from Truth, they aggressively deployed significant infantry directly into New Mombasa and picked up where Regret had left off while holding the human forces at bay until Truth's reinforcements arrived.
Despite Regret’s failure to secure the planet, Truth's plans would still be executed. </toggledisplay>
