Nightwater is a 2026 Steam factory and automation title developed by Studio Ashty and published by Studio Ashty and Irox Games. The campaign is set on a nighttime island where players gather resources, build production chains across four technology eras (Sticks & Stones, Bronze, Industrial, Future), expand the island biome-by-biome through a device called the Manifestor, and pursue the lighthouse endings.

Genre and setting
Nightwater is positioned inside the factory / automation / resource-progression space. The setting is a nighttime island framed by fog and a single distant lighthouse; the campaign moves through four technology eras that escalate the player's production capabilities, the Manifestor-driven biome expansion that opens new island regions, and five minigame systems layered onto the main factory loop. The lighthouse endings give the campaign a defined endpoint rather than an open sandbox.
Why Nightwater matters for launch-window readers
Nightwater is the title's debut on Steam; no prior Nightwater release exists, so this is not a sequel or remaster. The Steam page's release window (September 18, 2026) places the launch two days after this page's 2026-09-16 research date, which makes the lighthouse endings, the four-era axis, and the Manifestor the visible launch-window framing. Anything beyond what Steam lists — including price, hour-of-release, edition structure, demo, multiplayer support, and macOS/Linux/Steam Deck status — is not announced and is labeled as such on this site.
