 * Content=

Setting
The level begins on July 26, 2552 near Sword Base, an Office of Naval Intelligence research facility. The facility is located on the Babd Catha Ice Shelf in Eposz, near one of the poles of the planet.

Plot
Noble Team is deployed to Sword Base after a Covenant corvette begins attacking the facility. Due to the sensitive nature of the facility, orbital rounds are prohibited, forcing Noble Team to go groundside to defend the facility.

Two Falcons drop Noble Team around Sword Base. After Kat and Noble Six clear the courtyard outside the facility, they are ordered by Sword Control to proceed to the main gate. However, they are stopped by a pair of Wraiths, which Noble Six eliminates with a Target Locator.

A Pelican then drops off a Warthog, which Kat and Noble Six ride to reactivate a COM array to contact Command and an anti-air gun to help clear the skies. After completing their task, they meet up with the rest of the team at Sword Base.

They fight their way up through the atrium to the top floor, where Noble Six assists Emile in driving off several Phantoms and Banshees. A pair of Longswords are then able to push through as the corvette is destroyed by orbital defenses.

Noble Team is called back into Sword Base by Dr. Halsey, who reprimands Carter for not pursuing the Sangheili at the Visegrad Relay. She explains that the Sangheili were most likely part of an artifact retrieval strike team, and that the notes stored at the Visegrad Relay held very important information. Kat then hands over the data module she retrieved from the station. Carter and Halsey exchange barbs, and Noble Team leaves as Dr. Halsey examines the data module. }}
