Lot 2‘s Lighting expansion sends players to Neomuna, a city on Neptune that looks a bit like a late 1980s fever dream. Lot 2 patrol zones, Neomuna introduces a slew of new Lost Sectors – challenging optional dungeons a little off the beaten track. In Lightingthere are currently three new Lost Sectors: Hydroponics Delta, Gilded Precept, and Thrilladrome.
Whether you check them off your list as the first explorer to Neptune or play them again as part of the latest Lost Sector rotation, it’s worth learning where these planetary dungeons are located.
You can see the general location of Lost Sectors at Lot 2‘s map indicated by a chalky, door-shaped symbol. When you reach the general area of each, you might see the same symbol on a building or an ammo box or whatever. Still, figuring out exactly how to access each of them can be tricky.
We’ve tracked down the locations of each Lost Sector below Lot 2: Lightfall, plus instructions on how to start them all. As for actually completing these dungeons? Simple: don’t die.
Hydroponics Delta location in Destiny 2

The first lost sector, Hydroponics Deltais located in the southwest corner of Zephyr hall. When you reach the area, you will see a building surrounded by stairs with a landing pad on top. Follow the stairs all the way down and then look to the left. Across the canyon is a series of balconies that must have the worst views of Neptune. Bet the rent is still worthless.

One of those balconies is illuminated with golden light. Jump to that one and then follow the hallway. Eventually, you’ll find yourself in a room neatly bisected by a beam covered in neon-colored plants that almost certainly possess powerful hallucinogenic properties. There is a hole under the beam. Jump in to launch the Lost Sector.

Hydroponics Delta is here Power level 1760 — significantly higher than Lighting‘s base power level of 1600 – so you may want the Lighting Legendary campaign first to give yourself a welcome boost.
Gilded Precept location in Destiny 2

The second lost sector, Gilded Prescription, is located in the northeast corner of Ahimsa Park – a little outside the eastern boundary, nestled in the giant starship. You’ll see the Lost Sector symbol at the base of a stone pillar, suggesting you may need to climb it to find the entrance to Gilded Precept. Do not waste time.
Instead, jump off the cliff to your left and follow the natural outcrops until you can get no lower. To your left is a series of thin ledges leading to a vanishingly thin slit in the ship, flanked by two small golden lights. That leads to a corridor, at the end of which is the Lost Sector.

Gilded Precept is out Power level 1770so if you can’t handle Hydroponics Delta don’t even try it.
Thrilladrome location in Destiny 2

The last lost sector, Thrill dream, is located on the northern edge of Liming Harbor – geographically smack dab in the center of Neomuna. It is in a building with a two story atrium. Use the barrel (which contains more of those absolutely trip-inducing plants) to jump to the mezzanine above.

In the northeast corner you will see a vent. Shoot it and follow the corridor to the end.

One of the floor panels at the end of the hallway is a vent. Shoot that too. You are in the Lost Sector.

Thrilladrome is up Power level 1780. And while Hydroponics Delta and Gilded Precept pit you against armies of mindless Cabal, this particular Lost Sector pits you against the Vex.
