Tempest

Tempest is a multiplayer map that is featured in the Noble Map Pack for Halo: Reach.

Universe and lore
The map is set in an open environment with many openings and chasms, for a diverse amount of combat in a Forerunner environment on an unspecified Halo installation, in a complex of structures comprising a part of the ring's weather control system.

Layout
One side of the map opens to an open beach, with towering cliffs and a river on the other side. The terrain rises near the center where several large rocks provide cover. On opposite sides of the center are two large Forerunner structures, serving as the bases, accompanied by smaller structures and passageways around them. Connecting the main structures is a beam of energy that will disable any aircraft passing through it with an EMP. Man Cannons located on the side structures allow fast access to the flanks of each base. An additional Man Cannon at the front of each base launches players to their Machine Gun Turret situated atop a rock overlooking the central battle. On both sides of the map, small caves serve as alternate routes to the bases. There is also a crashed Longsword providing cover on the beach side.

Callouts
The following are locations on the map that are so named on the player's heads-up display during gameplay:
 * Forest Base

Forge
Tempest is considered to be a map intended for Forging on, albeit not as extensively as Forge World. The map retains most of Forge World's large item palette, and is one of two maps planned to support the Thorage functionality in the upcoming Forge update for Halo: Reach as part of Halo: The Master Chief Collection.

Production notes
Tempest was initially concepted as Halo 3 multiplayer DLC, before its inclusion in the Noble Map Pack.

The working title for Tempest was "DLC Medium".

Trivia

 * Every now and again, the beam of energy that connects the two structures will charge. This will send a pulse of energy along the beam's trail, bouncing off the hexagon patterned tile and into the sky. This is reminiscent of the bases in Valhalla.
 * Unlike most other beam-emitting towers, which intermittently emit a single bolt of energy, the tower on this map emits a continuous laser-like beam every minute or so.
 * Near the waterfall closest to the forest tunnel, there are fish that resemble Bluegills. These fish can be shot and killed.
 * The edge of the installation can be seen both to the left and right of the map.
 * The crashed Longsword has the same ID numbers as the Longsword that crashes in the Halo 3 level The Ark.
 * This map is likely located on the same Halo installation as Forge World is. Though the architecture is more akin to Installation 05 while Forge World's is more like Installation 04.
 * The birds found on this map are invincible to anything except a Spartan Laser, Scorpion round, or Gauss round, which will reduce them to smoke.
 * A radio is found beneath the crashed Longsword. It repeats a conversation in four segments.
 * Players can put a teleporter inside the power source like the glass isn't there and teleport themselves inside it, similar to the back of the bases in Avalanche, and the area inside the glass in The Coliseum in Forge World, but for those they have to go right up to the glass.
 * The towers in the background are strikingly similar to the ones John-117 transversed in the Halo 2 campaign level Regret.
 * The Energy Beam that connects the two bases not only can disable vehicles but if you stand in it for to long it can kill you, counting as a death from the The Guardians.
 * The crashed Longsword is much smaller than all others. The cockpit is too small for a Spartan.
