Breakneck

Breakneck is a multiplayer map included in Halo: Combat Evolved Anniversary and the Anniversary Map Pack for Halo: Reach. It is a remake of Headlong from Halo 2. It is the only Halo: Reach multiplayer map to be set on Earth.

Universe and lore
Breakneck is set in the city of New Mombasa, in a part of the docks known as Section 21, which closely resembles the Section 14 featured in Headlong. The area is lined by buildings on all but one side, which opens up to the sea with a view of a structure resembling the Uplift Nature Reserve and the city center. The playable area is dominated by a New Branch construction site, a hotel and an elevated road under construction.

New Mombasa's Superintendent is seemingly connected to the area as it's avatar can be seen on many parts of the map. The advertisement for the civilian Hog still appears on this map.

Trivia

 * The location of the map in New Mombasa, Section 21, is a reference to Section 14, the setting of Headlong. Both are also 7 references, as 14 and 21 are consecutive multiples of 7.
 * On the southern sea wall of the map, a screenshot of Headlong can be found.
 * The placement of the map in New Mombasa appears to be inconsistent with the city's Halo 3: ODST incarnation. Assuming the locations of the city's landmarks, such as the bridge of the Uplift Reserve, are consistent with ODST, the map should be situated near the southernmost main section of the Reserve. No skyscrapers or streets are present in the area in ODST. In addition, according to the player's HUD compass, the city center and the Mombasa tether are situated to the south and southwest of the map, respectively. Based on the way the city is presented in ODST, the aforementioned landmarks would be located to the north and northwest of the Uplift Reserve and thus the map's playable area.
 * The monument that resembles the Seventh Column near the water has noticeably changed since Halo 2. This is because the symbol is Bungie's registered trademark.
