Sandtrap

Sandtrap is a multiplayer map featured in Halo 3.

Summary
Sandtrap is set in a vast desert (possibly situated on Installation 00) with rolling sand dunes and some enigmatic structures, half buried in the desert. The origin of these structures is unknown, but they bear certain similarities to the "temples" on Installation 05.

It features odd Forerunner constructions and is encircled with a minefield that features vertically-launching mines to prevent players from venturing beyond its boundaries. Six large towers surround the outer extremities of the map, all connected by a large wall. The purpose and origin of these structures is unknown. The September 07 EGM stated that this was the site of a Brute excavation and UNSC forces (deployed from the frigate Aegis Fate, which hovers in the sky above the map) came along and removed them. It has a heavy emphasis on vehicular combat. Most of the vehicles in the game are on this map - for example, the "bases" are a pair of UNSC Elephants at opposite ends of the recently unearthed Forerunner ruins.

History
It was first announced in the June 2007 issue of Gamepro. It may also be the "large map" Bungie sparsely talked about in one of their updates. This was not one of the three maps featured in the public Halo 3 Beta. This map was originally named Shrine, but was confirmed to have been renamed to Sandtrap in the July 13, 2007 Bungie Weekly Update.

Unusable Vehicles

 * UNSC Aegis Fate (Hovering high in the background)
 * Phantom (Crashed and destroyed near the Banshee spawn)
 * Albatross Dropship (Crashed and buried near one of the Elephants)

Tactics and Tips

 * Upon picking up the Spartan Laser at the beginning of the game, get ready to destroy the Banshee, because more often than not, the enemy get it instead of your teammates, and you can eliminate the threat immediately.
 * If you start at the "Albatross" end of the map, if you are going for the Sniper Rifle, always keep an eye out for enemies camping up high on the other side, although a Bubble Shield is an easy way to get past this problem.
 * If you are playing this level on multiplayer infection, a good way to stay alive is for at least two people (non-zombies) to form an alliance and get to a warthog. Whoever is the better shot uses the turret and the driver continuously drives around the whole level on the path. As long as you have good reflexes and are a good shot you can usually kill the charging zombies before they reach the warthog.

Trivia

 * There are six real easter eggs on this level. To find them, overload the map and venture past the invisible wall in theater mode. An egg is located at the top of each tower. They only appear when close to the player, and are covered in cryptic messages.
 * GamePro has stated that Sandtrap "...has few ties to older Halo 2 maps, but its massive size recalls Relic."
 * The metal ring around Sandtrap resembles the Halo logo.
 * At E3, a map was shown on video. It was said by viewers to be called "Sand Trap" — in contrast to having been called "Shrine" before that point — and was labeled "... the largest map ever to be in Halo." The new name of Sandtrap was confirmed in the July 12 Bungie podcast.
 * Sandtrap is a favorite for machinimas. This Spartan Life has an episode on this level, and many people make vehicle race machinimas on this map.
 * Unlike other games, the UNSC Aegis Fate is not part of the "floating bitmap in the sky." If the player could fly anywhere, they would be able to actually go aboard the vessel.
 * Note that all vehicles at full speed (or players in custom matches where player speed is increased) can outrun the land mines surrounding the shrines. Note that land mines will attack the player even if in a low-flying Banshee. Driving into the minefield might be effective for losing pursuers (also note that there is NO safe place in the minefield, not even places where mines have already gone off, they will quickly re-spawn).
 * If the player manages to flip the Elephant, when approached, instead of the "Hold RB to flip [vehicle name]" message, the player will receive "Hold RB to flip... wait, what? How did you do that?"
 * You can go higher in actual gameplay in this map than you can in theater.
 * Another glitch is it is possible to escape the map and go on the outside and then on theater explore the ship above the map.
 * Due to a little investigation, it looks like a very fast, low textured Sentinel Beam (that normally stays at the spires but will rarely follow the player inside the map) is in control of when the Mines spawn. To best see this drive a Banshee along the bottom of the floor on the outside, when you see an orange-ish laser coming from a tower, cross over your vehicle, quit and go to Theater. When in theater follow the laser to both ends. At one you'll see the Mine spawn; the other end will lead to a spire at the other end of the map.
 * On several dunes to the side of the map where the sun is you can easily see the whole area of the map. Set up here and you can dominate. A common tactic is to take the sniper and use a Mongoose to drive over to the area and snipe. Good secondary weapons are Battle Rifles and Spartan Lasers, so any incoming threats can be eliminated, and the sniper can continue wreaking havoc from afar.
 * Another good sniping location would be the crashed Phantom, this also gives you a good position to see one side of the map and guard the Banshee spawn for your team.
 * Elements of Sandtrap seems to have been inspired from the Halo 3 Campaign mission, The Ark, and the Halo 2 multiplayer maps Relic and Burial Mounds.
 * If you exit a Banshee right at the top of the map, you will not receive any fall damage no matter where you land (Unless it's in the minefield).
 * The towers on the outskirts of the map appear to be the same kind of tower as in the level Epitaph, as seen in the above trivia.
 * It appears that the farther out you go the deadlier the mines become, finally becoming "super-mines" when you leave the map, with one hit killing players and going off almost instantly.
 * There have been several sightings of the Ghosts on this map. They allegedly have all yellow armor and use a Spartan Laser. One sighting during an offline Team Slayer match reported that the Ghost appeared wearing full Recon armor.
 * This is the only other map to contain an unusable Albatross dropship, the other one being Relic.
 * There is a crowbar similar to that of Gordan Freeman of the Half Life series. There is also a Level in Half Life 2 called Sand Traps. Half Life has long been considered Halo's biggest rival and this easter egg may have a similar effect as the Killzone Hellghast like EOD Armor Permutation, as Killzone was also marketed as a "Halo Killer".
 * This multiplayer map is the second largest in Halo 3, just behind the new DLC map Avalanche.
 * This map is famous for Infection games.
 * In the Elephant, there is a screen near the Mongoose with description about the vehicle.
 * There is a tree staff in the room with the computer on the floor that you can't pick up. You can't even make it move with a grenade. It could be an unknown Easter Egg.
 * Sandtrap has the highest barrier in the game allowing flyers of a Hornet or Banshee to give the player the full experience of a war game.
