''A Covenant carrier hovers above a city. A Phantom dropship flies rapidly over the city with a Pelican following closely. The scene turns into a hologram as the camera pans into Roland, who salutes the viewer.''

UNSC INFINITY BRIEFING ROOM

''2557 C.E.


 * Roland: Greetings Spartan! I'm Roland, the UNSC Infinity's AI. The Office of Naval Intelligence has cleared you to access a highly classified combat simulation. It's based on events that took place during the Battle of New Mombasa in 2552.''

''The scene switches to a devastated street. Two Unggoy and a Wraith advance through the street as the tank is unexpectedly hit by an explosive.''

''John-117 leaps out of a fire with an assault rifle in hand, firing. A Sangheili is hit in the head by a bullet as his shields flicker.''


 * Roland: Six years ago, a Covenant fleet attacked the city of New Mombasa. Any school kid can tell you that much.''

''Several Unggoy minors open fire. John-117 tosses a grenade between the Unggoy and kills them.


 * Roland: But many details of that attack were known only at the highest levels of government... Until now.''

''As the Unggoy corpses fly in the air, the camera pans into John-117 as he lowers his assault rifle. A Banshee flies above his head as he watches. A pelican fires a missile barrage at the Banshee as it goes around the corner.''

The camera swithces to the Solemn Penance above the city as several drop pods approach the from the sky.


 * Roland: While fighting raged throughout the city, Covenant forces secretly hunted for the portal to the Ark. But they were also looking for something else... The operation we'll study today began when we learned the Covenant found an artifact known as the Conduit.''

Several pods land and open, revealing several ODSTs.


 * Roland: Back in 'fifty-two, we sent a team of ODSTs in to secure the artifact.

A grid outline covers the scene as the ODSTs vanish and are replaced a Spartan-IV.


 * Roland: Our combat simulation is up and running, so let's see how you do playing through this operation as a lone Spartan. Good luck!
