0•X — BCH Prototype
A ship that's a real, understandable machine — with a genuinely programmable 16-bit computer at its heart.

 You wake aboard a small ship. Its power, cooling, air, and propulsion are simulated systems that actually work and actually fail — and the computer that runs it is a real emulated processor you program in its own Forth operating system, live on the CRT. Power it on, learn it, break it, and fix it: authored failure scenarios you diagnose from
the inside and solve two distinct ways — one at the terminal, one by hand.

This is BCH — the prototype, built to prove the machinery. No flight, saving, or story yet; the ship holds station while you operate and diagnose it. A full A16/AeturnisOS manual is included.

0•X is a hard-science-fiction space sandbox about living inside machines that are meant to be understood.

The project was heavily influenced by the canceled Mojang/Notch game 0x10c, but has since grown into its own setting, systems architecture, and simulation philosophy.

Humanity left Earth in the early 2000s after learning that an extinction event was unavoidable. Using a newly discovered and only partially understood technology called the Field Effect, hundreds of millions of people were sent outward aboard self-sufficient evacuation ships on deliberately different trajectories.

Something went catastrophically wrong.

An incomprehensible amount of time passed.

Only a handful of ships are known to have reached the region where humanity now lives, and local civilization has been rebuilding for roughly 1,200 years. Some Earth-born passengers are still in suspension. They are called Dreamers. When one wakes, they become Awakened.

You are one of them.

A World of Real Systems

0•X is built around the idea that a ship should not feel like a collection of abstract game menus.

It should feel like a machine.

Power, cooling, atmosphere, propulsion, sensors, computers, networks, and hardware are intended to behave as interconnected systems.

Failures propagate naturally. A broken pump does not create a quest marker. Coolant flow drops. Temperatures rise. Sensors report the consequences. Alarms eventually trigger. You decide what to do about it.

There is rarely intended to be one correct solution.

You might operate the machinery normally, diagnose the problem through instruments, repair hardware, reconfigure systems, or understand the computer well enough to automate the problem away.

The Computer Is Real

Ships use a fictional 16-bit computer architecture called the A16, running AeturnisOS.

It is not a decorative terminal.

The processor is emulated. The operating system runs on it. Devices are exposed through a real bus architecture. The machine is programmable from inside the game.

AeturnisOS includes a Forth environment, allowing players to eventually write real programs to:

• monitor ship systems
• automate procedures
• build custom interfaces
• process sensor data
• control machinery
• communicate over in-world networks
• write tools and utilities
• create software for other players
• replace parts of the software stack entirely

Programming is not intended to be mandatory.

It is another layer of mastery.

No Magic Safety Rails

0•X aims for a world where important systems are protected by engineering rather than arbitrary game rules.

• Ships can fail.
• Networks can be poorly secured.
• Components can be damaged.
• Software can be badly written.

Organizations can build infrastructure, services, software, security systems, logistics networks, and eventually industries of their own.

The deeper you understand a system, the more options you have.

A Civilization That Never Fully Left Earth Behind

For twelve centuries, Naturals—people born after arrival—have lived alongside newly awakened people from Earth.

That means Earth is both ancient history and living memory.

A historian may spend a lifetime studying Earth and then meet someone who remembers it personally.

Two siblings may have entered suspension together and awakened centuries apart.

A priceless archaeological computer may still be instantly recognizable to the player as a CRT, an Ethernet port, or a USB connector.

The remaining Dreamers are profoundly protected, not as artifacts, but as people who simply have not arrived yet.

Current Development

0•X is currently in prototype development.

The first playable prototype is planned around:

• a small ship
• a docking berth
• an A16/AeturnisOS terminal
• a handful of real system-failure scenarios

The prototype is intended to test one core idea:

Can a small simulated machine be interesting simply because its systems are coherent enough to understand?

That is the foundation everything else will grow from.
