Two clocks. Neither is official.

How long to beat AETHUS

HowLongToBeat, read on 28 October 2026, lists main story at 30 hours 45 minutes from 4 players, main plus extras at 29 hours 12 minutes from 2, completionist at 39 hours 17 minutes from 3, and all styles at 33 hours 15 minutes from 9. The extras row being shorter than the main row is in their table. I am not averaging it away.

HowLongToBeat and the IGN widget were both readable on 28 October 2026. IGN labels its widget HowLongToBeat, so these are two presentations of the same underlying source, not independent timing samples. Both differing presentations remain visible.

Samples under five people move when the next submission lands. Use them as a band of reports, and recheck the links before you plan a weekend.

Questions

Is 30 hours the official length?

No. It is HowLongToBeat's main-story average from 4 players. Pawsmonaut has not published a length.

Can you keep playing after the end?

Buried Treasure says yes. The completionist row is still only 3 players, so 100% time is not a promise.
