High Energy Lab

Outer Wilds guide · Learning about the Ash Twin Project

Located deep inside the Sunless City on Ember Twin, this Nomai research facility was used to test the physical principles behind the Ash Twin Project. You must navigate the rising sand within the caves of the Sunless City to reach it, where you can conduct warp core experiments using black and white holes. Exploring the facility reveals critical lore explaining how the Nomai created a 22-minute negative time interval.

Tips

To reach the lab safely, head through the Sunless City early in the time loop before rising sand blocks the lower pathways and cacti passages leading to it.
You can use your Little Scout to verify whether a patch of sand has covered the hazardous cacti along the trail before attempting to walk or boost over them.
