The '''teleportation grid''', also referred to as a '''translocation grid''',<ref name="nelson">[http://majornelson.com/2011/08/26/news-from-halo-fest/ '''Xbox Live's Major Nelson''': ''News From Halo Fest'']</ref> is a piece of [[Forerunner]] technology equipped to several important installations. Using [[slipspace translocation]] technology, the grid transports its users from one location to another in a compressed Slipstream field, not unlike starships using slipspace as a travel medium.

The [[Halo Array|Halo installations]] are equipped with teleportation grids, allowing their [[Monitor]]s to reach vital areas rapidly, and supervise their [[Sentinel]] charges. The [[Shield World]]s also possessed teleportation grids.<ref name="goo311">'''Halo: Ghosts of Onyx''', ''page 311''</ref><ref name="hw">'''Halo Wars'''</ref>

==Mechanics==
While the teleportation system on [[Onyx]] was made up of a network of [[teleporter|translocation platforms]], the teleportation grids on the Halo installations allow translocation from any point on the ring without the need for a teleporter. Teleportation through a grid is typically accompanied by rings of golden light that surround the individual being teleported.<ref name="two">'''Halo: Combat Evolved''', campaign level ''[[Two Betrayals]]''</ref><ref name="gravemind">'''Halo 2''', campaign level ''[[Gravemind]]''</ref> A teleportation grid requires massive amounts of energy to operate.{{Ref/Reuse|two}} The translocation grids on the Halo installations are supported by an array of "telemetry clusters", spire-like structures equipped with synchronization conduits which ensure the grid's operation at all times.{{Ref/Reuse|nelson}} Teleportation grids extend some distance away from the installation they are based on, as evidenced by the [[Gravemind]] being able to use [[Installation 05]]'s grid to translocate [[John-117]] into ''[[High Charity]]'', which was holding position near the installation.{{Ref/Reuse|gravemind}}

Translocation through a teleportation grid is not completely instantaneous; a sense of immense velocity could be felt when traveling through Installation 04's grid.<ref>'''Halo: The Flood''', ''page 288''</ref> Though the system merely transports its users through slipspace as opposed to disassembling and then rebuilding them in another location, the uncertainty errors involved are known to cause sensations of being put back together again "from a million pieces" when recovering from teleportation.<ref>'''Halo: The Flood''', ''page 237''</ref> In addition, the process typically causes feelings of nausea and disorientation on humans; [[Kurt-051]] described the feeling as if "his guts had been untwisted, and then dumped back into his body, inside out."<ref>'''Halo: Ghosts of Onyx''', ''page 316''</ref>

Teleportation grids make use of unmediated slipspace cores bound to them that generate stable, pre-computed slipspace routes between synchronised endpoints. Due to the fact that these devices have fixed endpoints (such as across an installation or its immediate vicinity), destination flexibility is sacrificed for safety, speed, and security.<ref name="WF11">''Halo: Warfleet'', p.11</ref>{{Ref/Reuse|gravemind}}

==Known grids==
[[File:1219939660 Avatars Halo Teleportation.jpg|right|thumb|[[John-117]] being teleported by [[343 Guilty Spark]] on Installation 04.]]
===Installation 03===
During the [[Skirmish on Installation 03]] on [[2557#July|July 26, 2557]], [[859 Static Carillon]], the [[monitor]] of the [[Composer's Forge]], temporarily disabled the [[Ur-Didact]] and used an emergency teleport feature present in [[Installation 03]]'s teleportation grid to displace the [[Promethean]] commander into the [[Control Room (Installation 03)|Control Room]]. According to the monitor, the control center was the only destination available to him, being the most secure location on the ring. Static Carillon then teleported [[John-117]] into the control room and, after ejecting the segment of the Halo housing the control room, he teleported the Master Chief aboard [[Blue Team]]'s [[GA-TL1 Longsword]] in orbit just before the detached section impacted the [[Composer's Forge]].<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 10|Issue #10]]''</ref>

===Installation 04===
[[Installation 04|Installation 04's]] teleportation grid was used extensively during the course of the [[Battle of Installation 04]]. The Installation's [[Monitor]], [[343 Guilty Spark]], first encountered [[John-117]] outside of a [[Flood containment facility]], and used the teleportation grid to transport them to the Installation's [[Library]], in order to retrieve the [[Activation Index]].<ref>'''Halo: Combat Evolved''', campaign level, ''[[343 Guilty Spark (level)|343 Guilty Spark]]''</ref> After the Index was retrieved, the Monitor used the grid again to transport the two of them to the [[Control Room]] to activate the Halo's final weapon.<ref>'''Halo: Combat Evolved''', campaign level, ''[[The Library]]''</ref> During the Master Chief's efforts to neutralize the Installation's primary firing sequence, [[Cortana]] tapped into the teleportation grid, using his [[MJOLNIR Powered Assault Armor/Mark V|Mark V MJOLNIR]] armor's fusion reactor to power a single jump, to a [[Truth and Reconciliation|downed Covenant cruiser]] having learned how from when she was in the Installation's control systems;<ref>'''Halo: Combat Evolved''', campaign level, ''[[Two Betrayals]]''</ref> however, Cortana's relative inexperience with the grid resulted in reorientation difficulties: the Master Chief was teleported upside down.<ref>'''Halo: Combat Evolved''', campaign level, ''[[Keyes]]''</ref>

===Installation 05===
[[Installation 05]]'s teleportation grid was unavailable during the [[Battle of Installation 05]] as it was being controlled by the [[Gravemind]] (formed beneath that Installation's Library facility) through the Installation's captured Monitor, [[2401 Penitent Tangent]]. Managing to ensnare both the [[John-117|Master Chief]] and the [[Thel 'Vadam|Arbiter]], it formed a tentative alliance with the two enemies in order to stop the rings activation - teleporting the [[John-117]] aboard [[High Charity]],{{Ref/Reuse|gravemind}} in orbit above the Installation, and the Arbiter near to the Control Room.{{Ref/Level|H2|[[Uprising]]}} The fact that it did not, or could not, use the same grid to teleport its own [[Flood combat form]]s to those locations indicates that use of it is restricted to non-Flood life forms and constructs.{{Ref/Level|H2|[[High Charity (level)|High Charity]]}}

===Installation 07===
[[Installation 07]]'s teleportation grid took on the form of portals, much like that on [[Requiem]]. On the Master Chief's orders, [[the Weapon]] opened a portal for him from the [[Command Spire (location)|Command Spire]] to as close as she can get them to where [[Jega 'Rdomnai]] had taken [[Fernando Esparza]].{{Ref/Level|Id=Command Spire|Hi|[[The Command Spire]]}} The two passed through a data cluster of [[Cortana]]'s memories, causing the Master Chief to see some of them.{{Ref/Level|Hi|[[Repository (Halo Infinite level)|Repository]]}}

[[Adjutant Resolution]] displayed the ability to teleport around the installation.{{Ref/Level|Hi|[[Spire (Halo Infinite level)|Spire]]}}{{Ref/Reuse|Command Spire}}

===Onyx===
The artificial planet [[Onyx]] also possessed a teleportation grid, which was used by [[Catherine Halsey|Dr. Catherine Halsey]] to transport the [[SPARTAN-II Program|Spartan-IIs]] and [[SPARTAN-III Program|IIIs]] across the megastructure during the [[Onyx Conflict]].{{Ref/Reuse|goo311}} After translocating Spartans to safety from a [[Joyous Exultation Covenant|Covenant]] attack in the [[Cartographer|map room]], Halsey used it to an advantage when assisting the Spartan teams to disable a [[Sentinel manufacturing facility|Sentinel manufacturing plant]] on Onyx, allowing the Spartans to rapidly traverse the immense facility.<ref>'''Halo: Ghosts of Onyx''', ''page 318''</ref> According to Dr. Halsey, an [[electromagnetic pulse]] generated by a [[nuclear weapon]] would have disrupted Onyx's teleportation grid for days, thus preventing the Spartans from using nukes to destroy the Sentinel factory.<ref>'''Halo: Ghosts of Onyx''', ''page 317''</ref> After the facility was destroyed, Halsey transported them to a room containing [[Team Katana]]'s [[slipspace field pod]]s and soon after, to the [[core room antechamber]] in the center of the megastructure. In the antechamber, the Spartans attempted to block [[Voro Nar 'Mantakree]] and [[Joyous Exultation Covenant|his forces]] from entering by placing the pods on various teleporter platforms. However, there were too many to block in the antechamber and Voro's forces were able to teleport in using platforms further away.

===Etran Harborage===
The [[Etran Harborage]] also contained a teleportation grid. On the [[Apex Site]] was a pad that could be activated through a voice command to transport its occupant to a desired location. In this pad's case, a ring rose up and surrounded the user with energy before disappearing, leaving the user at their desired destination. The Harborage also contained numerous small teleporters which acted similar to elevators, transporting anyone who entered them from a higher level to a nearby lower level and vice versa. Aside from aircraft, the main way onto the Apex Site was through a large pad teleporter at the top of a series of ramps that led to the Apex Base Site. This pad transported anything entering it to the Apex Site automatically.

In order to escape [[Arbiter]] [[Ripa 'Moramee]] and his forces on the Apex Site, Professor [[Ellen Anders]] activated the teleporter there with a command of "surface!" The teleporter sent Anders to a small bridge on the surface of the inner shield world. Smaller teleporters were then used by Anders and Sergeant [[John Forge]] to reach an evac [[Pelican]] and to help move around while building [[firebase]]s in the area.

In order to destroy the shield world, Forge and his forces began moving the {{UNSCShip|Spirit of Fire}}'s [[Shaw-Fujikawa Translight Engine]] reactor up the ramps leading to the Apex Site teleporter pad. After fighting through massive Covenant forces, an [[M312 Elephant]] was able to back the reactor onto the pad, teleporting it to the Apex Site. Due to the Elephant being outside of the pad at the time, only the reactor itself was teleported.

===Requiem===
[[Requiem]] contained a unique teleporter in the form of portals that would open to various locations on the shield world, including its surface and its core. [[Cortana]] was able to access and control the network after being put into a terminal and opened a portal to a tower in the planet's core so that she and the [[John-117|Master Chief]] could travel there to find the {{UNSCShip|Infinity}} and escape the planet. However, this awoke the [[Promethean]]s, who could also utilize the portal network to a great effect to move across Requiem. Cortana and the Master Chief later used portals to travel around the core and later to escape to the surface when the core started to collapse. After shutting down the [[particle cannon]]s protecting the gravity well generator and meeting with a personality imprint of the [[Librarian]], the two used a portal to rejoin the nearby human forces.<ref>'''[[Halo 4]]'''</ref>

During the [[Requiem Campaign]], the shield world's portal network was used extensively by the Prometheans and [[Jul 'Mdama's Covenant]] for travel. ''Infinity'' Science studied the network at both "[[the Gate]]" and "[[The Refuge (Requiem location)|the Refuge]]," trying to figure out how to control the network and shut it down. After the Gate was retaken by Promethean forces, [[Fireteam Crimson]] were deployed to reactivate some equipment so that ''Infinity'' Science could study the network. Dr. [[Ruiz]] was able to identify a piece of equipment that when activated, shut down the portals in the area. Based on the data from the equipment, Dr. [[Leslie Boyd]] gained control over the portals in the area and used them to bring Crimson to "the Refuge." During [[Battle at The Refuge|the subsequent Promethean attack]] on "the Refuge," Dr. Ruiz identified the device that allowed the portals to open which was destroyed by Crimson, shutting down part of the network and preventing the Prometheans from teleporting in.<ref>''Spartan Ops'', [[Memento Mori|S105 Memento Mori]]</ref> Despite this victory, at least part of the grid remained active at "[[Apex]]" where Crimson was later redeployed to shut down the active portals. Their mission was interrupted by a Covenant attack on the ''Infinity'' which required them to leave and help,<ref>''Spartan Ops'', [[Invasion (Spartan Ops)/Backup|S107 Backup]]</ref> but they returned after the attack was repelled and secured Apex, shutting the portals down.<ref>''Spartan Ops'', [[Expendable/Unfinished Business|S105 Unfinished Business]]</ref>

===''Mantle's Approach''===
The Forerunner ship ''[[Mantle's Approach]]'' possesed a teleportation grid in the form of portals similar to [[Requiem]] to allow beings to move about the ship easier. Once [[Cortana]] was inserted into the ship's systems, she was able to open portals to various locations throughout the ship before finally getting the [[John-117|Master Chief]] to where he wanted to go: the [[Composer]].<ref>'''[[Halo 4]]''', campaign level ''[[Midnight]]''</ref>

===Aktis IV===
A Forerunner structure on one of [[Aktis IV]]'s islands possessed a teleportation grid in the form of portals similar to Requiem.<ref>'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 15|Issue #15]]''</ref>

===Genesis===
[[Genesis]] possessed a teleportation grid, mainly taking the form of portals utilized by the [[Promethean]]s and [[Warden Eternal]]. However, the teleportation grid on Genesis did not seem entirely reliant on portals as [[031 Exuberant Witness]] was able to simply teleport an [[M820 Scorpion]] tank that had been inadvertently brought to the planet by a [[Guardian]] close to the location of [[Fireteam Osiris]] and [[Cortana]] was able to teleport [[Blue Team]] closer to her location.<ref>'''[[Halo 5: Guardians]]'''</ref>

===Triniel===
A [[Builder]] facility on [[Triniel]] possessed a teleportation grid in the form of translocation pads for easier transport around the installation. After the facility was reactivated by [[Rion Forge]], [[343 Guilty Spark]] was able to access the grid and use it to teleport the crew of the ''[[Ace of Spades]]'' to the level containing the lab with the [[slipspace flake]]s and then the level with the [[design seed]] lab. After they had succeeded in their mission, Spark used the grid to return them to the surface.<ref>'''[[Halo: Renegades]]''', ''Chapter 28''</ref>

===Mount Kilimanjaro===
A Forerunner site beneath [[Mount Kilimanjaro]] possessed a translocation pad that was used by [[343 Guilty Spark]] to teleport the crew of the ''[[Ace of Spades]]'' to just below the summit of Mawenzi.<ref>'''[[Halo: Renegades]]''', ''page 303''</ref> An ONI science team that later examined it determined that the teleporter was a static portal going only to that one location.<ref>'''[[Halo: Renegades]]''', ''page 320''</ref>

==Trivia==
{{Linkbox|gallery=yes}}
*The effects accompanying teleportation through a grid are present in ''[[Halo 3]]'' when a player flips inside a vehicle. It can be viewed easily in theater mode.
*In co-op mode, when one person enters a loading zone, but the other person is separated, the other person will teleport with the same animation as the Halo teleportation grid, even if the level is set on Earth.
*In ''[[Halo: Combat Evolved Anniversary]]'' and ''[[Halo 2: Anniversary]]'' the teleportation effect is different than in the original games. In the former, the game still has the ring effect, but it's not as elaborate. In the latter, the Master Chief and the Arbiter vanish in gold light and then appear to come out of a portal at their destination.
