Build a sprawling automated factory across a hand-crafted solar system. Mine, smelt, refine, then route everything by belt, train, and cargo ship — powered by a real electrical grid. 15 orbital launcher milestones stand between you and a finished starship. Steam EA Oct 12.

Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Aethel Mine is a deterministic factory-building simulation on a custom engine. The first nine launcher projects are playable today, and the rest of the game (interstellar travel, new ores, new machines, a redesigned interface, multiplayer) is still to be built. We are releasing in Early Access because we want players' experience to shape that work: which production ratios feel wrong, where the difficulty curve is too steep, what is missing from the factory-building toolbox, and which problems appear on real machines with real, large factories.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access for around a year, and we will adjust that as the work goes on. The time frame is a plan and not a promise.”

How is the full version planned to differ from the Early Access version?

“The Early Access version is a complete single-player game up to launcher project 9 and stops there, telling you so. We plan to add, roughly in this order:
- Travel between star systems, with new worlds, new ores and their ingots, alloys and components, and a much more powerful power source.
- More things to build, including larger storage chests.
- Later launcher projects, up to the fifteen currently designed.
- A redesigned user interface.
- Cooperative multiplayer. It is not in the current build.
- Steam features such as achievements.
Content and order may change with player feedback; we will describe each update in its patch notes.”

What is the current state of the Early Access version?

“The current version (0.2.2) is a single-player game you can play from your first drill to the ninth launcher project:
- A procedurally generated world for each seed, with terraced terrain, lakes and several biomes; other worlds of the star system can be visited.
- A tech tree of several hundred items and recipes, with smelters, assemblers, refineries and chemical plants.
- Belts, splitters, mergers, pipes, roads and rails, with gravity and pressure limits on slopes.
- A power grid with visible lines, and heat that machines radiate.
- Fourteen milestones handed to the headquarters, then a launcher that takes numbered projects.
- Background music with a volume setting. Sound effects are limited and will be extended.
Known limits: there is no multiplayer yet, the interface will be redesigned in a later update, and the game ends at project 9 for now.”

Will the game be priced differently during and after Early Access?

“We plan to raise the price as substantial content and features are added, so the Early Access price reflects a game that is not yet complete. We do not plan to change it before there is significant new content.”

How are you planning on involving the Community in your development process?

“We read the Steam community hub and player reports, and the game has a built-in bug report (pause menu: it writes a plain-text report that you can read and send yourself). Feedback on balance, on difficulty, on what is missing from the tools and on performance with large factories decides the order of what we build. We publish patch notes with each update.”

About This Game

Pure industrial engineering. No abstractions.

Aethel Mine launches you onto a wild, procedurally generated frontier spanning over 10 square kilometers. Designed for uncompromising efficiency and deterministic simulation, the game forces you to build, route, and optimize vast industrial complexes, ranging from basic metallurgy to galaxy-scale megastructures.

Here, physics is your primary adversary. Terrain is not just a visual element: fluids obey hydrostatic pressure, electrical networks incorporate real rotational inertia, and every thermodynamic inefficiency directly impacts your installations.

Key Mechanics

True 3D Isometric Topology : Take advantage of natural plateaus with gravitational slides that consume no energy, or pay the steep price to pump fluids and propel inclined conveyor belts along steep cliffs. Watch your pipelines: uncontrolled drops will burst pipes under hydraulic hammer effects.

50-Level Vertical Stacking : Eliminate spatial bottlenecks. Create complex exchanges by stacking up to 50 independent logistic layers per tile, thanks to compact bitboard-based occupancy management.

Thermodynamics and Thermal Radiation : Each power-hungry arc furnace or CVD chamber diffuses heat to adjacent tiles. Plan industrial ventilation corridors and exploit cold biomes before rising ambient temperatures slow down your machines.

Mechanical Torque and Network Collapse : Energy is not a simple abstract global value. Transmit raw torque via mechanical shafts before unlocking electrical cables. Maintain network frequency under heavy load: a transformer overload can trigger a cascade failure, forcing you to perform emergency manual restarts.

Exact Ratio Distribution : Split and merge flows using carousel mechanisms synchronized to the cycle. Guaranteed exact ratios eliminate production jerks and downstream shortages.

Planetary Specialization and Galactic Logistics : No single world can sustain production in the late game phase. Exploit high-gravity terrestrial planets for raw material extraction, install cryogenic factories on airless ice worlds, and leverage orbital transit windows via electromagnetic catapults and automated freight lines.

Scale in the Millions : Progress through 15 demanding technology tiers. Go from hand-forged iron plates to self-replicating Dyson swarm architectures and laboratory event horizons.
