To restore power in the Underpass during Recursions and Iterations, find the central room with four Power Cores, then carry charges from three active cores in nearby areas back to it. Follow the yellow markings, cables, or floor tape, and return promptly with each charge.
Where to find the Power Core room
The objective takes place in the Underpass. Find the central Power Core room first: walkthroughs describe four cores there, with one already powered and three inactive. This is where you need to bring the three charges. The guides identify this destination and the carry-and-return mechanic, but do not establish a definitive official map or exact room names. AllThingsHow’s September 23, 2026 walkthrough and ShowGamer’s September 22, 2026 walkthrough describe the objective and yellow route cues.

How to find the three Power Core charges
From the central room, follow the yellow tape, markings, or cables to an active core in an outlying area. Take one route at a time; the guides agree on the marked-route approach, but differ in how specifically they describe the surrounding rooms and landmarks. Treat the yellow cues as your guide rather than relying on an unverified room-by-room map.
- Locate the destination: identify the central room and its three inactive cores.
- Follow a marked route: trace the yellow markings, cables, or floor tape to an active core elsewhere in the Underpass.
- Take its charge: carry the charge back along the route you used, without detouring.
- Power a core: return the charge to the central room and use it on an inactive core.
- Repeat: follow another marked route to an active core and bring its charge back. Do this until all three inactive cores are powered.
Why you should return quickly
The walkthroughs describe a charge as time-limited, so head back promptly after picking one up. The practical strategy is to learn the route on the way out, then retrace it with the charge rather than exploring or taking a different path. No code or hidden switch is described as necessary; this is a route-and-carry puzzle. AllThingsHow’s September 25, 2026 walkthrough also describes the marked-route return loop.
