Ghost Town

Ghost Town is a multiplayer map set in the same jungle as Sierra 117. It is a water purification facility built in the 24th Century that has since fallen into ruins. Its main function was to take melted water from Mount Kilimanjaro, purify it, then pump it to the rest of Africa. It consists of three buildings surrounded by hills and trees. The inside of one building features rubble and vegetation that has overgrown during years of the desolation. The level is a bridge between nature and failed human civilization. It has many levels and open air catwalks with sights down to semi protected alleys where you can "rain death from above". These catwalks have entrances to the main building as well. Ghost Town is featured as one of the maps in The Legendary Map Pack available now.

Bases
Ghost Town consists of three main buildings. The buildings are not symmetrical, as it is an asymmetrical map. The defenders spawn in the "Interior Base", seen in the lower right corner of the overhead image, while the attackers spawn in the Tunnel. Originally the attackers spawned in the building, and the defenders in the Tunnel, but it since it has changed.

The “Atrium” area: Is a long lean hallway with a walkway that connects to the Pump Station building. The Atrium area also houses the Sniper Rifle. It features rubble and vegetation that has overgrown during years of the desolation.

The Pump Station: A three story building with catwalks leading to the Interior Base. It has several entrances, and is connected to the Atrium via a wooden catwalk. On the opposite side of the building it is connected to the area where the Shotgun spawns by a similiar catwalk.

The Interior Base: This is where the Defenders spawn. It connects to the Pump Station via a catwalk where a Bruteshot spawns, and has an exit leading towards the Shotgun spawn.

The Tunnel: This is where the Attackers respawn. The Tunnel has three entrances/exits, made up of ruined parts of pipes, similar to those running parallell to the Tsavo Highway

Overview
Starting from the Mongoose in the upper left corner of the image (see overview image in the image section) is one of the two bases (the other is in the bottom right of the image). The “Atrium” area (the building in the upper right corner, indicated with a 3) is a long, lean and overgrown two-story hallway with a catwalk that connects to the Pump Station, a three story building with catwalks that exit to the Interior Base (again in the lower right corner) and second level walkways to the Shotgun (where the Bubble Shield is located). From Shotgun spawn, if players head to the right after coming from the Pump Station, they’ll be able to stay on a path that feeds down into the Overshield and there’s a second level walkway overhead housing the Rocket Launcher and grenades. Directly to the left and under the Plasma Grenades that spawn near the Rocket Launcher is a tunnel that curves behind and empties almost into the area where the number 2 Camera was taken.

The Pump Station’s main room is a bombed out shell of a structure with "God Rays" filtering through the ceiling - and that top floor has a walkway that leads toward Sniper in the Atrium and a walkway (where the Brute Shot spawns) that leads to the Interior base in the lower right corner. That multi-level base has a few connecting walkways that lead to an elevated and dilapidated structure that overlooks Active Camo, and a Gravity Lift spawn and is positioned above a dark hallway that funnels into the Atrium.

For the most part players have quick and dirty methods at their disposal, via quick jumps or equipment to get to the map’s second and third level catwalks and there are long sight lines from the Attackers’ base (Rocket Launcher side) down in front of Atrium and also down the Woods side (Shotgun side).

Forge

 * Wooden ramps similar to the "bridge" object in the Heroic Map Pack.
 * Wooden platforms attached to metal legs, effectively making a small watchtower.
 * Curved metal walls and concrete barriers are useful for filling in ruined gaps in the level.
 * Impassable and indestructible barred walls have been added too.
 * A new object called FX can change the color, tint, brightness and contrast of the whole level. It appears as a blue transparent orb with a small camera inside. You can combine them and use equipment to make cool effects.
 * You can access the upper area of the Atrium by placing a ramp or bridge between two support beams and then place a teleporter on top of the ramp/bridge.
 * Behind the concrete ramp in the Pump Station, there is a fenced off passageway which can be accessed by spawning a respawn inside. It is advised that you spawn a two-way teleporter node inside upon gaining access.
 * This method can also be used to access the ruined brick building between the Atrium and the Interior Base

Tactics

 * Grab the Overshield when the game begins. It may not help against the Rocket Launcher, but with so many brutal weapons, you can easily die on this map.
 * Remember, there is a Shotgun on this map. It is near the cut-down tree near the municipal house. Take it and use it at your disposal. This is also works well with the Overshield being nearby.
 * The Atrium can be a great place to hide or camp.
 * Dual Spikers and Plasma Rifles work great on this map.
 * Before going into matchmaking, make sure you have an understanding of the map, so you know where things are and where to go.
 * As it is always suggested that the destined, winning team either possesses the Energy Sword or the Gravity Hammer, controlling the Shotgun works toward the theory. A combination of a Battle Rifle and a Shotgun works equally well on this map.
 * Camp in some of the trees near the Overshield spawn.
 * Take advantage of the fact that no one in Multiplayer dual-wields Plasma Rifles, wipe them out and dominate, showing your opponents that the Plasma Rifles are not yet dead in Multiplayer.
 * This is an "open" map used for lively close combat, a similar, comparable map would be Guardian for its central, blood-drenched arena.

Trivia

 * This map's codename was O.K. Corral (A reference to the Gunfight at the O.K. Corral.)
 * Many thought this map would be a map similar to Tombstone because of the codename O.K. Corral which was a famous gunfight in Tombstone, Arizona.
 * Speculation was this map could have been a remake of Turf or Tombstone, considering the fact they both sport catwalks, alleys, and multiple levels.
 * It is set in and based on the same jungle as the Halo 3 campaign level Sierra 117.
 * The pipeline seen running parallel to Tsavo Highway is from this structure.
 * There was certain individuals within Bungie that wanted to name the map Mortar, but however the name Ghost Town stuck with the map instead.
 * The first part of the The Storm is also called "Ghost Town".
 * Bungie staffers also jokingly called Ghost Town "that Counter-Strike map" referencing the popular PC shooter game. Specifically referencing the combination of the maps "Italy" and "Aztec" which Ghost Town has more than a passing resemblance to.
 * You can hear artillery shells exploding in the background every once in a while on Ghost Town.
 * Swallows can be found on this map.
 * On occasion, items will spawn outside of the map.
 * The upper invisible barrier of Ghost Town is one of the lowest in the game, in order to keep people from camping on rooftops.
 * There is a hidden room in one corner of the map that has a fractured ceiling with rear and concrete sticking out as well as a hole in the brick wall, you can use the trick with the turret that people use to get out of The Pit's fence on the hole and there is 3 levels of hidden room to snipe in.
 * The map makes a great race track due to its rectangle shape appearance.
 * A lot of excellent hiding places, such as the slab of collapsed concrete below the large building, and the collapsed brick room between the Atrium and Interir Base, have invisible walls to stop people from camping.
 * If you listen you can hear the sound of Sniper Jackals turning on their Beam Rifles.
 * In the recent ViDoc, Victor Leon of Bungie studios pointed out the "Water Barrels" had in fact no water in them at all.
 * Under the Pump Station, beyond the concrete ramp, there is a fenced-off passageway leading to another part of the building. It seems to have been fenced off by Bungie for the final version of the map. This passageway is actually quite large, but resembles more an abstract room. It is easily accessible via the forge. See Forge above for details.
 * The map bears a resemblance to the Halo 2 map, Turf. The resemblance is most easily seen with a birds-eye view. This slight resemblence is more of a layout similarity than of playstyle resemblence, as in Ghost Town, the player can enter the buildings, and there are no alleys like in Turf.
