Prepare the final progression route and use the official Bye Bye Furnox achievement as the verified ending signal.
Complete the remaining main objectives, city and production gates, then follow the Furnox route until Steam unlocks Bye Bye Furnox: Stomp Furnox into the ground! That achievement is the verified completion signal.

Finish active mission groups and their final handoffs so the ending route is not hidden behind an incomplete city, NPC, or production requirement.
Keep the materials required by visible final objectives available and clear machine queues before committing resources to optional furniture.
Use the exact objective text and named interactions shown in the release build. Competitor boss values and phase counts are not treated as verified here.
Complete the route until the objective resolves and Steam checks the Bye Bye Furnox condition.
Failure branch
Audit incomplete missions, city upgrades, NPC dialogue, required builds, and uncollected physical recipe papers. If the Furnox objective is active, follow its current wording rather than an older demo walkthrough.
Completion signal
The ending route is complete when Steam records Bye Bye Furnox and the final objective no longer remains active.
Start over
Return to the first condition that is not yet true instead of repeating the final action.
