==Transcript==
{Cutscene}

''As the Spartan escaped with the [[Conduit]], he received an emergency distress call from a top secret [[New Phoenix ONI facility|ONI base]] in [[New Phoenix]]. Researchers there were studying a mysterious [[Forerunner]] artifact. When the [[Jul 'Mdama's Covenant faction|Covenant]] used the Conduit at the [[Altar]], they activated [[Slipspace portal|portals]] all over the [[Milky Way|galaxy]]. One of those portals was in New Phoenix, and... Well, you can guess what came next.''

''What's more, the only way to close the portal was to bring the Conduit to the base—and use it to deactivate the Forerunner device.''

''The Spartan raced towards [[Earth]]... But the [[Promethean]] invasion had already begun.''

{Closing cutscene}

''Outstanding performance in our simulation, Spartan! There's no telling how many lives would have been lost if the Promethean onslaught had continued.''

''Instead, we closed the portal and stopped them in their tracks. As for the Conduit itself? It jumped into [[slipspace]] before we could grab it. Official press reports referred to a "[[Shaw-Fujikawa Translight Engine|slipspace drive]] coil accident." Had people learned the truth, the resulting panic could have destabilized the [[Unified Earth Government]] at a crucial time.''

''Luckily for us,  that didn't happen. But the Conduit isn't the only Forerunner artifact out there. The lost treasures of Forerunner civilization offer us great opportunity, and even greater peril.''

-{All missions gold}
-''Greetings Spartan! Congratulations on your exceptional performance in our simulation! I've got a classified update for you, if you're into that sorta thing...''
-''Since the events in New Phoenix, ONI has been working day and night to track down the missing Conduit. We suspect it broadcast an activation signal to Forerunner portals across the galaxy.''
-''Portals we don't even know about. And while some of those portals may be dormant, others are still very much active.''
-''We need a special team of Spartans to seek out these portals, shut 'em down, and stop the spread of the Promethean threat.''
