Rio de Janeiro

Rio de Janeiro is a major city in the South American country of Brazil.

History
In late 2557 or early 2558, Rio de Janeiro's population swelled as an increasing number of asylum seekers from the former Covenant emigrated to Earth; Spartan branch fireteam Majestic, minus Gabriel Thorne, was deployed sometime after to maintain order. Later, a Sangheili terrorist attempted to detonate a contraband HAVOK nuclear warhead in the city, but was ultimately stopped by UNSC special operations forces.
