Glacier (Halo: Reach map)
Glacier is a Firefight map in Halo: Reach. The map is set in an underground glacial cavern beneath Sword Base and features a Forerunner structure. It is part of a section in the campaign level The Package.
Glacier is a medium-sized asymmetrical Firefight map. The map consists of a main building where the player spawns and numerous snowy pathways separated by jagged rock pieces: a main pathway in the center, a circular pathway to the right, which also leads to two bridges and another pathway to the left that encircles an inaccessible building. The base and its pathway are also encircled by numerous rocks that make excellent cover. At the bottom of those rocks is a weapon holder which contains a Spartan Laser. There are also weapon racks for a Sniper Rifle and a Rocket Launcher. The Target Locator does not appear due to the map being underground. The building can also be climbed by using a jetpack and can serve as an excellent sniping position. The main spawn building has an exterior section with an awning overhead and an interior section with a small exit to the left, which leads to the exterior of the left pathway.
