Teleporter

A Teleporter is a device that allows for instantaneous transport over short distances to another teleporter or teleporter exit point. Unlike Forerunner Teleportation Grids which are able to transport an individual without any visible device, teleporters have a device on both ends.

Multiplayer
In the Halo games, teleporters appear mostly in Multiplayer, with the exception of Halo Wars. They are most often seen on Forerunner and Covenant structures, on levels such as and. In some multiplayer maps such as, however, teleporters can be found on clearly human-constructed structures. This is most likely a non-canon gameplay element, as no canon source has indicated that humans would possess such advanced technology. Teleporters usually appear green, with the exceptions of, , and , where the teleporters are blue.

In Halo 3, teleporters were present in hardly any multiplayer map because Bungie thought it was too easy to "camp" near them and get easy kills. Instead, Man Cannons took their place for the most part. Despite this, teleporters were reintroduced in the recently released map, as well as appearing on. Teleporters are available, however, in Forge for every Halo 3 map. In Halo 3, when a person enters a teleporter and is going at a high speed (most likely caused by a jump from above), they keep their momentum and come out at the same speed, but in the direction it is aiming (indicated by the glowing polygon at the teleporter's base).

Trivia

 * A clever, though usually considered cheap, strategy involving teleporters is to go through one, then immediately move backwards. If the space behind it goes back far enough, then you can camp behind the teleporter.
 * In Halo: Combat Evolved, Halo 2 and Halo 3, it is possible to block the teleporters (especially in Blood Gulch) with a vehicle or by simply standing on them.
 * Telefragging is the use of a teleporter to kill somebody standing on top or inside another teleporter. The player standing on top of the "receiver node" of the teleporter will have the screen slowly turn white before being killed as a "suicide" (this only occurs in Halo: Combat Evolved, 'Halo 2, and Halo Trial, in Halo 3'' it says it is blocked).
 * In Forge, if teleporter A connects to both teleporters B and C, then if a player enters teleporter A in the opposite direction of the glowing indicator on its base, said player will be transported to teleporter B every time; conversely, if the player enters teleporter A in the same direction of the glowing indicator on its base, said player will be transported to teleporter C every time.
