Sword Base

Sword Base is a multiplayer map appearing in Halo: Reach.

Universe and lore
The map is set in the Office of Naval Intelligence's SWORD Base, situated along the Babd Catha Ice Shelf of the Eposz super-continent on the Human Inner Colony world of Reach. The base was attacked by the Covenant early in the Fall of Reach, and was destroyed somewhat during Operation: WHITE GLOVE much later.

Prior to this though, the atrium boasted a minor collection of recovered artifacts and materiel from elsewhere, including those that were recovered in Operation: GUARDIAN LANCE on Jericho VII.

Layout
The map is described as "the stepson of Prisoner and Boarding Action". It is a small, asymmetrical slayer map with three gravity lifts and a series of bridges and walkways leading over a central atrium. It features many external and internal stairways and rooms, making it an appealing map for Infection games as there are many strategically controllable areas and vantage points.

The following are locations on the map that are so named on the player's HUD during gameplay:

Production notes
It was featured in the Halo: Reach Multiplayer Beta.

Sword base has changed very much from the beta version, the walls around the facility having been destroyed and burnt, with large amount of debris on the ground. The Gravity Lift in the center has also been weakened.

Trivia
Using the Forge turret glitch, one can get behind the large door found on the ground level, and out of the map.
