Sector 4

Sector 4 is a location in the Final Fantasy VII series. It is one of the eight sectors in Midgar, and is visited briefly during the events of Final Fantasy VII and Final Fantasy VII Remake.
Little is seen of Sector 4 itself, as Avalanche primarily visits the sector to reach Mako Reactor 5. In both games, the locations visited in Sector 4 are unrevisitable and cannot be re-explored once the story has progressed beyond them.
==History==
Sector 4 was built around 1974-75. Midgar construction was complete in 1976, meaning this would be when immigrants first moved to settle in Sector 4.
Bugs began to make nests in the Sector 4 plate, and were mutated to become monsters by mako. Shinra largely neglected the problem as they had not caused an accident.
===Original continuity===
In "To the No. 5 Reactor", after the success of the Mako Reactor 1 bombing mission, Barret Wallace' Avalanche cell plan another mission on Mako Reactor 5. In the early hours of the morning after the first mission, they board a train for the Sector 4 Station. The train uses a new ID scan system, and the fake IDs made by Jessie Rasberry fail and the party plans to jump off the moving train into the train tunnel.
Unauthorized personnel are discovered on board prior to when the check was meant to happen due to modifications to the ID cards made by Jessie, meaning the party has to move down the train to the end cart before the lockdown. Cloud Strife, Barret, and Tifa Lockhart jump off the train while Biggs, Wedge, and Jessie stay on board in disguises. After jumping off the train, they come to Shinra Electric Power Company security sensors and search for another way, using a duct to the lower Sector 4 plate. There, they find the rest of Avalanche have made it safely, and their route to the reactor is secured.
===Remake continuity===
In "Home Sweet Slum", following the success of the Mako Reactor 1 bombing, Barret's Avalanche cell plan another bombing. Barret plans only to bring himself, Biggs, Wedge, and Jessie, due to a disagreement with Tifa, and a desire to not become too reliant on Cloud. Biggs is sent onto Sector 4 early in the morning to secure their route. However, plans change in "Mad Dash" when Jessie is injured by Whispers and Wedge was injured the night before on a mission with Cloud, Biggs, and Jessie, causing Barret to hire Cloud and bring Tifa along.
In "Dogged Pursuit", Cloud, Barret, and Tifa board the train. Though their fake IDs hold up at the first scan, an emergency scan catches them, forcing them to jump off the train into the Corkscrew Tunnel and take Biggs' plan E, making their way through its train tracks to reach the lower Sector 4 plate.
After making it there, in "Light the Way", the three traversed the plates, having to deactivate several of the sector's sun lamps; Tifa hesitated as the sun lamps are important for those in the undercity due to its lack of natural sunlight, but Barret reminded her that the destruction of the reactor would shut the sun lamps down anyway, causing her to go along with the plan reluctantly. Finally, the group found Biggs, who had secured their route easily thanks to the distraction caused by their jumping off the train. Biggs gave them grappling guns and then returned to the Sector 7 slums.
==Geography==
The Sector 4 underplate is a series of winding ducts, passageways, ladders, and tiered platforms supported by steel beams, located underneath Midgar's Sector 4 plate, and suspended high above Midgar's undercity. The plate is connected to Mako Reactor 5, and several monsters dwell within it.
As seen in Final Fantasy VII Remake, the lower Sector 4 plate is divided into labeled sections that house the immense floodlights that dwarf the size of most of the buildings in the area used to provide artificial sunlight to the undercity, as well as control rooms to oversee them. Three line the wall with Sector 0, and two are on the wall with the outer plate both facing outwards. Deactivating these provides power to platforms that move across the plate. A large ventilation fan is also present, and a path across a metal pipe runs directly along the ventilation fan's airflow. Thanks to a lack of inspectors keeping the area up to date, several monsters attracted by the mako fumes have come to dwell here, with cobwebs and nests across the various platforms and maintenance rooms. Many of the slats of the walkways have fallen off, making traversal dangerous, and power has been distributed unevenly, requiring the "sun lamps" to be turned off to reactivate the automated security and some of the moving platforms. Several pipes and vents pump out the pollution generated from the upper plate sending it down below.
==Gameplay==
===Final Fantasy VII===
*To the No. 5 Reactor
Sector 4 is visited by Cloud, Barret, and Tifa on the party's way to No. 5 Reactor.
The field comprises only a few screens, where some enemies such as the Grashtrike and some Shinra defenses are fought. Along the way, the party can interact with Wedge and Jessie before meeting Biggs at the end. The Sector 4 field map also contains the Winding Tunnels from the train to reach Sector 4, and then the reactor.
===Final Fantasy VII Remake===
*Light the Way
Sector 4 is visited throughout Chapter 6, "Light the Way," and comprises a series of passageways and tiered platforms on the way to Mako Reactor 5. It is explored by Cloud Strife, Barret Wallace, and Tifa Lockhart shortly after they leave the Corkscrew Tunnel of the previous chapter. The group traverse the Section G and Section H portions of the plate.
Throughout the Sector 4 area, the party must interact with the plate's sun lamps to deactivate them in order to create a suitable path across the elevators and platforms. On the way, the group fight monsters in the form of the grashtrike enemies, as well as Shinra's defenses in the form of Sentry Rays. While exploring, two notable materia can be obtained: the during "Collapsed Passageway," and the sidequest during the "Inside the Ventilation Fan" sidequest.
Compared to Final Fantasy VII, the Sector 4 area is greatly expanded. The objectives to interact with the sun plates are entirely new, as are the side objectives. Another major difference is that the interactions with Wedge and Jessie are not present, and that the field map for Sector 4 and for the Corkscrew Tunnel are different.
==Other appearances==
===Final Fantasy Brave Exvius===
Sector 4 appeared during the exploration event "Destroy the Reactor". It leads directly to Sector 5 Reactor.
==Behind the scenes==
In the PlayStation translation of Final Fantasy VII, the dialogue lines Jessie says are slightly different from what she says in the PC and later versions. In the former, she states she made Cloud's ID card "special", while the latter translations clarify that she modified his card.
"The ID scan problem on the trainwas all my fault.""I made your ID card special...So that's why it happened...""I put my heart into making it."But I failed."	"The ID scan problem on the trainwas all my fault.""I modified your ID card...And that's what did it...""I did my best...But I failed."

In the scene showing Cloud and Zack right outside Midgar in Final Fantasy VII, the Midgar upper plate for Sector 4 is absent. While Crisis Core -Final Fantasy VII- states the Sector 4 plate is last on the schedule for completion, Final Fantasy VII shows it fully complete and in place, while Sector 6 is the sole sector still under construction as of the game's opening.
