Hostile Atmosphere quest is a side mission in Once Human that tasks you to investigate strange Stardust readings. This quest offers a mix of exploration detective work and combat as you uncover the source of the pollution.

Let’s break down how to complete the Hostile Atmosphere quest in Once Human.

How to Complete Hostile Atmosphere in Once Human

To start the quest head to Tall Grass Inn and talk to Andreas. She’ll ask you to look into the rising Stardust Pollution in the area.

Follow the quest marker south to a Deviant-infested town. There you’ll find a Rosetta Researcher with a Stardust Diffuser.

Should You Kill or Spare the Rosetta Researcher?

When you talk to the Rosetta researcher you’ll face a big choice: kill them or let them go. This decision impacts how the rest of the quest plays out.

If you choose to kill the researcher:

• They won’t reveal the other diffuser locations
• You’ll need to destroy the nearby diffuser
• Return to Andreas with the job half-done
• She’ll be upset but still give you a reward

If you spare the researcher:

• They’ll give you a tracker for 3 more diffusers
• New map markers will appear for the diffusers
• You’ll need to travel to destroy them all

Find and Destroy All Stardust Diffusers

The diffuser locations can be tricky to find. One is near a good rabbit hunting spot. Another is in an area with hostile Rosetta Soldiers. Approach all 3 diffusers from different angles until you see a “destroy” prompt.

After handling all the Stardust Diffusers go back to Andreas at Tall Grass Inn. She’ll be happy with your work if you find them all.

Tip: Some players have trouble interacting with the diffusers. If this happens keep trying different angles or restarting the game.
