What the developers have to say:

Why Early Access?

“As a small indie studio building a niche product, we value the input and feedback of our users. To build the best possible product for our target audience, we need time both to gather feedback and incorporate changes in the finished product as soon as possible.”

Approximately how long will this game be in Early Access?

“The Early Access phase is expected to last at least one year.”

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

“The final version of Tungsten Moon may include:
  • Multiple types of moon bases
  • A storyline that you can follow
  • More realistic spacecraft systems

What is the current state of the Early Access version?

“The initial Early Access release includes:

FEATURES

  • Support for XBOX and PS controllers, OpenXR VR support, and keyboard/mouse.
  • User configurable controller input mapping.
  • Full and accurate spacecraft physics.
  • The game has a limited set of tasks of varying difficulty.
  • Full open-world access to explore the entire million square kilometer map of the Tungsten Moon, with no boundaries or time limits.

LIMITATIONS

  • World resources, NPCs, and objectives are under constant development and will change.
  • Spacecraft internal system models are under constant development and will change.
  • Spacecraft layout, appearance, and UI are under constant development and will change.
  • Spacecraft onboard computer and UI are under development and/or not yet available.

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

“The Early Access price will increase as the product approaches its targeted feature set.”

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

“We view community involvement in Tungsten Moon Early Access as an essential part of our development process! Feedback, feature suggestions, and bug reports are all welcome through our Discord or via email.”

About This Game

Tungsten Moon is a spacecraft simulation, set on a small, fictional moon made entirely of tungsten metal. The moon is 600 km in diameter, with a surface gravity similar to Earth's moon. You are placed on the surface of Tungsten Moon, in a small spacecraft with enough fuel to travel to any other point on the moon. How did you get there? Why don't you know how to pilot the spacecraft? How will you get home? These and other questions await your investigation, as you learn to manage your ship, search for resources, find supplies, and answer the essential mystery of how you got in this mess, all while exploring over 1 million square kilometers of terrain.

Although you are on a strange moon in an alien solar system, your spacecraft seems to have been built in the final decades of the 20th century. The on-board computer provides some information and automations, but you will have to learn to fly it by the seat of your pants. Eventually, you may be able to upgrade or revise the ship's software, expand your map of Tungsten Moon, and even enter orbit around it.

Your spacecraft and lunar physics are 100% authentic. Spacecraft systems and sensors are modeled with a strict attention to detail and are faithful to the capabilities of 1980s technology. Safety margins are razor-thin, and the consequences of careless inattention come swiftly on Tungsten Moon.

FEATURES

  • The simulator is designed with game controllers, flightsim joysticks, and VR in mind, yet can be played with just a keyboard and mouse.
  • True open-world access to every square inch of Tungsten Moon.
  • Spacecraft physics is accurate and correctly simulates the Tsiolkovsky rocket equation, fully considering the decreasing mass of the ship in flight.
  • Orbital physics is modeled using RK4 Runge-Kutta fourth-order integration.
  • Moon rotation, orbit around its planet, and the planet's orbit around its sun are modeled with a physically accurate timescale.
  • Once the game begins, the world clock advances in real-time with every second you play. Over time, the sun sets, the planet rises, and the appearance of the sky is continually changing. Locations that are in bright sunlight at the start of the game, may be in complete darkness five hours later.
  • The spacecraft onboard computer software is user-extensible using a variant of the Forth computer language, which was once a popular platform for spacecraft avionics.
