Ember Twin

Outer Wilds guide · Third major planet exploration

Ember Twin is a desert planet continually filling with sand poured from its sibling, Ash Twin. You must explore its subterranean caves, the Sunless City, and the High Energy Lab before rising sand cuts off access to lower levels. Key tasks include finding the Nomai's quantum research and locating an entrance to the sealed core of the Ash Twin Project.

Use your Little Scout to check for ghost matter in dark caverns before stepping into unfamiliar tunnels.
Talk to Chert at different points throughout the 22-minute loop to hear his dialogue change as more supernovae appear in the sky.
