Fly towards Midgar when you are ready to continue with the next portion of the game. A cutscene will begin as soon as you get close enough.

You will get to choose your party members one last time before parachuting into Midgar, but your team should still be ready to go following the fight against Diamond Weapon.

Sector 8 Underground

Follow Cait Sith down the pathway to find a Save Point where you can save your game and still swap party members if you would like to. Approach Cait Sith when you are ready to continue and follow him down the ladder.

Take the upper pathway (shown in the screenshot below) and follow it around the catwalk and onto the pipes. You will come across a treasure chest that contains an Elixir.

There is another treasure chest on the right side of the pipes that contains a Megalixir.

Go back to the long ladder that you came down to get into this area and, this time, go down the long set of stairs that were closer to the screen. Take the ladder downwards, which will lead to the next screen.

Head left once you reach the platform at the bottom of the ladder and take the other ladder at the back of the screen back up to the top level. At the top of this extremely long ladder is a treasure chest that contains an Aegis Armlet.

Return to the platform below and proceed to the right side of the screen. The ground will collapse beneath Cloud as he attempts to jump across the gap.

Continue to the left instead and climb the ladder on the red pipe.

Follow the pathway around and enter the ventilation duct marked with a red rim around the opening. The treasure chest on the right side of this platform contains an Elixir, while the one on the left contains a Starlight Phone weapon for Cait Sith.

Climb down the ladder and jump down to the ventilation duct on the right side of the screen. At the end of the duct is a ladder that leads to a treasure chest that contains a Max Ray weapon for Barret.

Go back down to the platform with the two treasure chests and take the stairs leading up to the upper level. Save your game at the Save Point before you go through the next doorway.

The next area Cloud will enter is a small ventilation shaft that leads into the Winding Tunnels.

Winding Tunnel

Travel through the vent and a little way down the corridor to trigger the next boss battle. If you have completed the Wutai side quest to recover your Materia from Yuffie, you will have the option to fight the Turks.

Elena will say, “What are you doing! Let’s go!” and two options will appear on the screen. You can either select “Okay, let’s end this” to engage the three Turks in battle or select “No, let’s not” to avoid the fight altogether. You should engage in this fight so that you can steal the items that each of the Turks possess.

Travel towards the camera once the battle has concluded. Continue past Barret, and you will eventually find a Power Source six screens south, followed by a Guard Source two more screens south, a Mind Source, and a Magic Source two more screens south from there, and one more screen will help you reach the W-Item Materia.

Travel back to where you fought the Turks by going north. You will need to take the pathway leading right at each of the splits, through areas 1, 2, 3, and so on, until you reach area 8 (the numbers identifying each area are written in red on the back wall).

In Area 8, you have the option of either going:

• To the left: This direction leads to the next section of Midgar and continues the game, or…
• To the right: This direction leads you to “Area 0”. Take a left in the next section and climb the ladder to find yourself back at the Shinra Building.

The Shinra Building has some optional items that you can pick up at this point in the game. There is no way to return to the Shinra Building later if you proceed past this point (specifically, once you engage Proud Clod in battle), so you should revisit it now while you’re here. Otherwise, if you prefer not to, you can skip down to the Winding Tunnel section.

Revisiting the Shinra Building

Cait Sith will come running out of the entrance to the Shinra Building and warn you that this is not the right direction to get to the Sister Ray. Ignore him and go into the building.

Go up to the second floor and enter the Item Store on the back wall. You can purchase the following items:

• Potions
• Phoenix Downs
• Antidotes
• Eye Drops
• Tents

There are two treasure chests at the back of the shop, which were previously locked shut. One contains a Master Fist weapon for Tifa, and the other one contains a Pile Banger weapon for Barret.

You can climb up the stairwell to the top floors again if you choose. There is a Behemoth Horn weapon available for Red XIII about halfway to the top. This weapon is fairly strong, but it’s hard to justify the climb—a more suitable alternative is to take the elevator up to the 59^th floor and take the stairs back down.

Enter the Shinra building and ride the elevator up to the 59^th floor. After you have picked up the Behemoth Horn from the stairwell, take the elevators on the right side of the screen, which allow you to use your Keycards and access the various floors.

Travel to Floor 63, and you will find a Grow Lance weapon in one of the rooms. This item was misspelled as “Glow Lance” in the original version of the game but was corrected in the PlayStation 4 version.

On Floor 64, you will find Cait Sith’s Ultimate Weapon, the HP Shout, in one of the lockers in the changing room.

Check the vending machine in the room below. If you spent the 250 gil attempting to buy the “Shinra Gym Special Drink” during your first visit, you can now choose to bang on the machine to receive a Mind Source and a Speed Source.

You’ve now done everything that you can do in the Shinra Building. Backtrack to the Winding Tunnels, where you fought the Turks. You can use this second elevator to return to the first floor.

Winding Tunnel

Travel to the intersection just north of where you fought the Turks (the one listed as intersection “8” and pictured in the screenshot below). This time, take the pathway to the left of the “8”. Cloud will automatically climb the rafters to the streets above.

Continue forward to initiate the next boss battle.

Remember to equip Cloud’s new Ragnarok sword after the boss battle.

Head north to the top of the screen after the battle has concluded. In the next area, you will find two treasure chests, one containing an Elixir and one containing a Mystile armor, as well as a Save Point.

Switch your party around at the Save Point so that it includes Barret. There is a treasure chest coming up that contains Barret’s Ultimate Weapon called Missing Score. You can only see the treasure chest if you have Barret in your party.

Proceed up the stairs toward Cait Sith and then past Vincent. The treasure chest is located halfway up the catwalk—use the screenshot below for reference. Return down to the Save Point if you prefer not to keep Barret in your party.

There are three upcoming boss battles, which are all fought, one after the other, in succession. Ensure that you have all of your Ribbon accessories equipped.

The story continues back on the Highwind. There is a ton of dialogue to pour through before moving on to Disc 3.
