Region 5: Pipes & Underground

Empty pipes and half-buried interiors are the last layer of the old civilization — and the coziest. An official screenshot shows a warm, lamp-lit workshop cave where the Merlies appear to have settled in among human leftovers; the store text lists exploring empty pipes as one of the game's core traversal verbs. Underground spaces mix tight squeezes with open chambers, and light itself becomes a landmark.

Underground routes suit the game's "at your own pace" promise: no enemies to flee from, but thorns, drops and dead ends that punish rushing. The payoffs are some of the game's most charming set pieces — communities making do with what the old world left behind, exactly the solarpunk upcycling spirit the developers describe.
