Mission to Destroy Installation 04

On September 22, 2552, Spartan John-117 set out on a mission to destroy Installation 04, bringing an end to the conflict on the ring.

Prelude
On September 19, 2552, the exited slipspace over Installation 04 and engaged the Covenant Fleet of Particular Justice in orbit. The vessel was critically damaged and eventually forced to crash-land on the ring, with all hands evacuating via any means available. For the next three days, marine forces led by Captain Jacob Keyes and Major Antonio Silva would engage the Covenant across the surface of the ringworld in a campaign of raids and strike, with the Covenant retaliating in turn.

On September 20, Captain Keyes would lead an investigation to a believed-Covenant weapons cache, only to lead to an outbreak of the Flood contagion, which soon began to rapidly manifest itself across the ring. Simultaneously, Spartan John-117 would learn that Halo's purpose was that of a weapon to wipe out all life in the galaxy, intending to starve the Flood, and set out to destroy the installation to prevent the ring from falling into Covenant hands, and prevent the Flood from escaping.
