Quest FAQ
How do I start Project Jonah?
At Platform Omega, find the control room beneath the platform. Connect one fully grown human to the control socket, then send the call out to sea. A Human Seed is not enough.
Where is the Unlisted Tower for The Isolation?
Unlisted Tower is at approximately 113, -21 on the in-game map grid, about 4.8 km east-northeast of Lazarus Complex. The Isolation objective is to reach the tower's summit. Climb to the top of Unlisted Tower. A radio message then leads into Quarantine Stacks and the journey to Quarantine Stack AMEN.
How many Sweethearts do you scan for Friendly by Design?
The current documented target is 10 deceased Sweethearts; Update 03 footage showed 25. Follow the count in your own quest log. The later 10/10 screen is from July 11, 2026, before Update 5.5.
What does Still Listening reward?
Still Listening rewards the Twin Jet, shown as TIDERIPPER TWIN in the skill menu.
Should you launch or recycle the Star Child?
After obtaining the Star Child memory, True Choices presents two objectives: grow the “perfect” human and launch them into space, or recycle the Gold Standard memory. These are separate paths offered by the quest. We do not recommend either path because the outcomes and rewards of both routes have not yet been verified.
