Death's Door Walkthrough

Objectives
1 Horizon Forbidden West - Death
・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 Horizon Forbidden West - Death
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 then approach and activate the nearby green console. 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 Horizon Forbidden West - Death
・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

After crafting and using the igniter on the door, head deeper into the facility until you are faced with a room full of water and some metal structures.
6
・Restore Power to the Terminal
Head onto the large broken metal platform and go down the path to the left, climbing and grappling when needed. Note that you'll encounter some vent panels that you need to use the Pullcaster on. You'll eventually find yourself at a door with a small crack and some climbable bars on top. Don't forget to lower the ladder..
7
・Restore Power to the Terminal
Head inside the room by climbing the bars above the door. There will be a door with a red battery inside. In this same room, there will be a generator on the wall. Take the energy cell from it and place it where the red battery is to open the door. This will be one of the main puzzle features of this area so remember this process.
8
・Restore Power to the Terminal
In the next room, after grappling to the upper level, push the crate down the hole and drop down as well. There will be a room with two red batteries but you'll only need to activate the one on the larger wall. Move the crate to the other side and climb to the upper level. .
9
・Restore Power to the Terminal
Ignite and enter the wall on the right side then take the energy cell from the first area. Transfer it to the previous rooms' red battery on the larger wall. This will activate some holograms and open the door on the second level.
10
・Explore the North Side of the Facility
This door will lead back to the area with the water. Lower the ladder on the edge and climb the ladder leading up. From here you'll need to use your pullcaster on the grated rectangular structure to get across..
11
・Explore the North Side of the Facility
When you dont see anymore climbable points, use the glide feature to get onto the rusty platform. Continue grappling and climbing until you're in the room on the other side.
12
・Unlock the Door
Use ignite on the wall to proceed to the next room. There will be two scannable data points, some locked doors and doorway that's open. Go down the doorway that's open and scan the info to give you the code (7482). The info should be titled Bad Urges. Enter the code beside the locked door to proceed to the next area.
13
・Find a Way to the Inner Gene-Locked Hatch
You'll eventually head out of the room and back to the area with water. The next path to take will be down to the northern central door. Similar to the previous steps, use your focus, pullcaster to maneuver and climb to this door.
14 Horizon Forbidden West - Death
・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.
15 Horizon Forbidden West - Death
・Examine the Console
・Examine the Access Console

Use the console, then shoot the arm. Check the GAIA repository.
16 Horizon Forbidden West - Death
・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.
17
・Search for a Way Out
Follow the path ahead. In the next room, where machines are shooting at you if you stay too close to the surface or go up, submerge and head to the north west. There will be a door surrounded by blue lights. Open the door and head there. 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.
18 Horizon Forbidden West - Death
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.

▸Next Quest: The Dying Lands

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

Horizon Forbidden West - Death Door - Erik
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

Horizon Forbidden West - Death
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.
