Death's Door Overview

Basic Information

Death's Door Walkthrough

Objectives
1	・Go to the Coordinates Recovered from the Spire Head to the objective. This is a good time to call your mount if you did the Override a Charger objective in the previous Quest. You can test out the Shieldwing on the way, but it won't take you far.
2	Upon reaching the water, swim across toward the objective. If you go underwater here, you can get a Deepwater Kindle Weed, which you will need for one of the following steps.
3	・Watch the Hologram ・Examine the Device ・Investigate Sylens' Workshop ・Follow the Orb's Trail ・Examine the Orb Scan the two datapoints at Sylens' lab. To follow the Orb's Trail, follow the path ahead until it reaches a door. The Quest marker will not show you the way, so you simply have to continue following the path on the ground ahead of you. Some machines will be on the path, so call your mount and ride past them if you want to get through quickly. If you fight, you can go ahead and grab a Leaplasher Spark Coil from a Leaplasher, which is needed for one of the following steps.
4	・Gather Resources for the Igniter If you haven't obtained them so far, you'll need a Deepwater Kindle Weed from underwater in the lake you passed, and Leaplasher Spark Coil, which can be obtained by detaching the Power Cell from a Leaplasher. Leaplashers are found in the enemy group from the previous step. The Power Cell is on the Leaplasher's back, so you'll have to target it deliberately to try to detach it. Check its location in the Notebook, and target it with the Focus if you have time.
5	・Craft the Igniter ・Ignite the Firegleam ・Enter the Facility Head into the facility. In the next room, head left at the fork. Use the Pullcaster to take off the metal lid and grapple across. The door will be blocked at the end, but you can climb over the top. In the next room, take the Energy Cell from the wall behind you and use it to power the door.
6	・Restore Power to the Terminal Climb up and go through the door on the right, then drop down. In the room below, push the crate to the far wall and jump up to climb up to the walkway. Ignite the Firegleam on the wall. Take the Energy Cell from the next room back into this room, and use it on the socket on the far wall. You can use the Energy Cell on the socket on the closer wall first to unlock some items, then remove it to use on the far wall socket.
7	・Explore the North Side of the Facility Climb up the ladder and use your Pullcaster on the pole with grating opposite the door. Maneuver across and use the Shieldwing to reach the other side. Climb up and use the Shieldwing again, then ignite the Firegleam on the wall.
8	・Unlock the door You can open the door with the code 7482. The answer to the riddle is found in a datapoint in the room opposite the locked door, titled Bad Urges.
9	・Find a Way to the Inner Gene-Locked Hatch Pry open the door in the next room and climb up. Go through the door, and platform to the ledge closest to the Gene-Locked Hatch. From there, use the Pullcaster on the nearby pole with the metal X. Go across, then use the Pullcaster again on the pole with the grating ahead. Head across and finally, use the Shieldwing to glide to the door.
10	・Examine the Console ・Examine the Access Console Use the console, then shoot the arm. Check the GAIA repository.
11	・Kill the Mysterious Attacker Attacking him will not do anything, so focus on avoiding his attacks. First, activate the terminal. Then, shoot the connectors (red spots) on the Spider four times. Next, you'll need to hit the couplings (orange lines) on the top of the Spider's Head. Each of these must be shot twice.
12	・Search for a Way Out Follow the path ahead. In the next room, the Attacker will shoot at you if you go up, so come up to breathe, then submerge again. On the opposite side of the room, you will find a door underwater, so open it and go through. Go left, and ascend on the opposite end; in the next room, use the Pullcaster to open the vent. Press down the left control stick to swim faster throughout this segment.
13	Submerge again before you get shot at and go through the door. Go through the door and resurface, and go into the vent. Go through the next door and ignite the Firegleam to escape and end the Quest.

Death's Door Code Solution

After making your way to the other side of the facility, you will have to go inside the crack on the left. You will then see the door that requires a code on the left side to proceed. You can enter the 7482 code immediately on it, or you can scan the Bad Urges Text Datapoint on the opposite side where the locked door is.

Tips and Strategies

Wait for the Attacker to Stop Shooting

When battling the Mysterious Attacker, although his attacks come quickly, he will still take a moment between each attack. Use this time to aim for your target on the Spider. Using Concentration by pressing down the right control stick will allow you to take more time for each shot, giving you a moment to dodge the next attack after shooting.

Lower the Ladders Down

You can lower the ladders down as you progress through to the Inner Gene-Locked Hatch. They will serve as a checkpoint so that you won't have to start all over again if you fall into the water.
