Sentinel wall: Difference between revisions

Despite the efforts of the robotic keepers, the Flood were released when the [[The Arbiter (character)|Arbiter]] penetrated the defences and deactivated the containment shield around the wall. It is unknown if such a structure exists on the other Halo installations. During the battle on Installation 05 the Arbiter was sent into the wall to deactivate the shields keeping the [[Flood]] in the Quarantine Zone in order to let other [[Covenant]] forces fly over the wall towards the Library. It is possible that this is what caused the Flood to be able to capture Covenant craft and attempt to use them to escape Halo, as seen in ''[[Halo: Ghosts of Onyx]]''.

When the UNSC forces landed on the Ark, they were ordered to secure a landing zone for the ''Forward Unto Dawn'' to land. Unfortunately, the teams mounted up near a crashed Pelican, pushed through Covenant Loyalist forces but found the Sentinel Wall. The teams regroup at the Sentinel wall after saving the [[Sentinels]] from the Covenant Loyalists. After finding the path to the landing zone, the UNSC teams and the Sentinels join forces and fight their way through the Covenant Loyalists gaurding the entrance. The Sentinels had another task so they fly over a part of the wall to help defend it. After the ''Forward Unto Dawn'' landed and deployed a convoy of 3 Scorpion tanks and a Warthog, Keyes had a plan to go through the wall instead of over it. So the UNSC forces returned to the Sentinel wall and found a way through it, the [[Master Chief]] goes into an above entrance himself as Guilty Spark opens the doors for him and finds a switch activating a Light Bridge in which the convoy proceeds in through a tunnel, [[Constructors]] can be seen flying around a generator type object and seem to be repairing it while Sentinels fly around and guard them. It is known that the Sentinel wall is part of the Cartogropher building because somewhere near the canyons half of the building can be seen forming from the Sentinel wall.

*A section of the ''Sentinel Wall'' is clearly visible on the [[Halo 2]] Campaign levels [[Delta Halo (Level)|Delta Halo]] and [[Regret (Level)|Regret]], as well as Multiplayer map, [[Containment (Level)|Containment]], a multiplayer map only featured in the ''[[Halo 2]]'' Multiplayer and [[Halo 2 Vista]] map packs.

*It is unknown whether the other Installations have this feature, as the player would have bypassed the wall due to the monitors use of the teleportation array on [[Installation 04]].
