Follow this guide to find DEMETER's coordinates in Horizon Forbidden West. Learn how to defeat Quen ambushers, navigate The Greenhouse, and locate Test Station Ivy.
Walkthrough
- 1Head northwest on the map to find The Greenhouse facility. If you see The Stand of the Sentinels Tallneck, go northwest from it.
- 2Enter The Greenhouse via the small bridge to its southeast. Invisible walls prevent entry from other perimeter points.
- 3Upon approaching the ruined building, you will be ambushed by Quen warriors. Some will attack from the second floor with arrows, while others will rush you from the building. Use cover and be ready to counter melee attacks.
- 4Utilize Blaze barrels around the compound, especially on the upper floor, by detonating them with fire ammo. Loot bodies and chests inside the building after the fight.
- 5Continue around the building to find the entrance to The Greenhouse.
- 6Inside, a Holo Projector will activate. Proceed forward until you find DEMETER blocked by a Metal Flower.
- 7Scan the ADMTN_WRTH/BRN_DREAM_1 Datapoint to the right of the Metal Flower using your Focus.
- 8To the left of the Metal Flower, use your Pullcaster on a metal clamp on the wall to destroy it and open a passage.
- 9Use the Pullcaster again on a vent panel to open it.
- 10Enter the elevator shaft and use your Focus to highlight handholds for climbing.
- 11Climb to the next opening and enter a room. Find the A Difficult Beginning Datapoint.
- 12Activate the Holo Projector in the room to learn about the facility. Your objective is to find Test Station Ivy.
- 13Approach the window on the eastern end of the room to find a rappel point to descend to the ground.
- 14Engage the Quen soldiers in the courtyard. Use stealth by isolating enemies with rocks or use Acid ammo on Metalbite containers for explosions. Be aware of the Imperial Guard with a bomb launcher.
- 15After defeating the enemies, explore the area. A crafting bench is available. Pry open a chest under one of the tents with your spear to find the rare [Berserker Hunting Bow].
- 16Go to the marker and through the door to trigger a cutscene, introducing the NPC Alva.
- 17Engage in dialogue with Alva. Choose the option to continue the quest.
- 18Run to the other console and activate it. A Datapoint named Growing Concern is located next to it. Activating the console will open a hatch.
Tips

- The Berserker Hunting Bow, found in a chest, can be very useful for making enemies attack each other.
- Human enemies are generally weak to fire.
- Use your Focus to tag all enemies before engaging, especially in the courtyard area, to maintain awareness of their positions.
