A slim rocket on its launch pad at dusk, ringed by a small lit factory of machines and belts on a dark moon

Longdusk

A peaceful factory on the moon.

Your ship came down hard on a dead moon. Mine it, belt it, automate it, and build the ship that takes you home. There is no combat. The only thing working against you is the dark.

Free to try on iPad. Unlock the full expedition with one purchase: no ads, no subscriptions. Launch price $6.99 USD, from 7 November 2026 until 30 November 2026.

A factory by day: drones carry cargo between smelters and the ship on its pad — A working factory by day, at three times speed

The same factory as dusk falls and the base lights come up — The dusk falls and the base lights come up

The launch countdown, ignition, the climb, and the results — Charge the launch and fly home

A lunar base at dusk: miners, smelters and belts around the crashed ship — Build a factory on a quiet moon

The base at night, lit by base lights against the dark — Keep the lights on through the long dusk

The radial build wheel open over the board — Made for touch: press, pick, place

The research panel, open on Electronics — Research the road home

The escape ship standing on its launch pad — Assemble the ship that takes you home

Every machine in the game, laid out side by side — Mine, smelt, refine, then automate it all

The results screen after the launch: the ship named, its mission patch and the run in numbers — Fly home, and see what it took

What is Longdusk?

Longdusk is a factory-building game made for iPad. You play one suited survivor beside a crashed ship, with a little oxygen, a weak reactor and a handful of parts. Everything else you make yourself: miners on the ore, smelters behind them, belts between them, and in the end every part of a ship.

It is a game about automation, and about getting through the night. A heliostat pours out power by day and nothing after dark, so you bank daylight in accumulators or watch the factory brown out at dusk. Air is a grid of its own, and its reserve has to last the night too.

Build and automate

Mine ferrite, cuprite and ice. Smelt plate and wire, then grind regolith into silica, glass and circuits. Name two machines and the belt between them lays itself.

Keep the lights on

Power and oxygen are two grids with day and night in them. Size your storage for the dark, and the factory hums all night long.

Go further

Robots build what you order and haul drones fly your standing orders. Outposts claim new ground. Drive a moonbuggy, fly a jetsuit, and survey the far band beyond the dust.

Fly home

Fit the ship stage by stage, then charge the launch. Your grid has to carry the full load to the very last second.

Made for iPad

Press and hold for the build wheel, then tap to pick and place. Undo a misplaced order, pause machines and belts, and speed time up to three times.

Your expedition

Every expedition is a fresh moon in three sizes, at standard, hard or extreme difficulty. It saves automatically and plays fully offline.

Free to try

The free trial is the first valley. Research up to Electronics and Robotics, automate glass and circuits, and complete the trial's goal: a Survey Beacon held at full power, unbroken, to see past the dust.

Unlock Full Expedition adds the rest of the research tree, the far band beyond the valley, and the ship home. It is a single purchase (launch price $6.99 USD, from 7 November 2026 until 30 November 2026), it carries on the save you're playing, and it restores on every iPad signed in to your Apple Account.
