''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.

''Six years ago, a Covenant fleet attacked the city of New Mombasa. Any school kid can tell you that much. But many details of that attack were known only at the highest levels of government... Until now.''

''While fighting raged throughout the city, Covenant forces secretly hunted for the portal to the Ark. But they were also looking for something else...
