Death's Door: Walkthrough

In order to track down Sylens, head to the coordinates you recovered from the Spire west of Stone's Echo. You'll happen upon a workshop where Sylens will tell you about an Orb. Follow its trail to LATOPOLIS, ensuring to salvage scrap from the Leaplashers along the way. You'll need this later. Be careful of Glinthawks in the area. If you get stuck, make sure you're literally following the Orb's trail on the ground, and not necessarily the trail from your Focus.

Once inside, Sylens will task you with crafting an Igniter, using parts from the Leaplasher site nearby. Use the workbench just outside LATOPOLIS to build it once you have the requisite pieces, and enter the dungeon. It's flooded, and you'll need to head to the left to begin navigating the area. Remember to always drop the ladders in the flooded room so you can easily get back up. Use the Power Cell in all the terminals to unlock Holograms and open doors.

Navigation is particularly awkward in the flooded room, so remember to use your Focus to highlight climbing ledges and your Pullcaster to grapple onto faraway ledges. Also, look out for yellow beam with blue grates on them: these can be pulled down with your Pullcaster to create new platforms you can climb on. If you do fall in the water, then unfortunately you'll have to swim back to the nearest ladder and try again. There is Firegleam on the far left side of the room, just beyond the Inner Gene Hatch, which has a chest and some loot behind it, but seeing as the platforming can be quite finicky here, we'd argue it's not worth your time taking the effort to get it, especially if you keep falling in the water.

Once you've recovered the GAIA backup you'll encounter some new, futuristic looking foes. In order to deal with the mysterious stranger, Erik, shoot out the glowing red brackets on the RECLUSE Spider. You can't actually attack Erik, but this will give you an escape route. Stay under water to avoid Specters, and get out of LATOPOLIS with your life.
