Getting Started

The first day

1. Leave the pod. KORA walks you through the first objectives (top left). The pod recharges your suit tanks and revives you if you die.
2. Watch the bars: oxygen, water, food. Drink with G, eat with F. On breathable worlds the visor opens automatically and oxygen is free.
3. Dig and gather with the hand drill (LMB). Everything is real matter with real mass: your suit carries 600 kg. Drop excess with Shift+RMB on an inventory slot, or store it in a crate.
4. Build with B (machines) and the welder tool (blocks). Machines need their construction cost in your backpack.
5. Craft in the assembler menu C near the pod or a workshop: tools, medkits, components.

Heat, gas and fire are real

• Every 10 cm cell has temperature, pressure and contents. Heat spreads, gases mix and rise, liquids flow and boil.
• Burning and smelting produce CO₂. Outdoors it blows away; indoors it accumulates and will suffocate you. Ventilate (vents, air purifier) or capture exhaust with a gas pump next to the furnace chimney.
• Wood self-ignites around 300 °C. Lava ignites everything. Fire spreads with wind.

Research

Build a Science Lab and feed it materials to produce sample kits (higher tiers need plates, wire, pyrite, heavy ice, helium-3 regolith). Spend samples in the research panel to unlock machines and upgrades: see Research tree.

Automation basics

• Conveyors move solids; inserters (feeder arms) load and unload machines with filters.
• Pipes move fluids and gases; pumps push them; tanks store them.
• Cables carry power from solar panels, generators and turbines; batteries buffer it.
• Signals (levers, sensors, gates, timers) switch machines on and off automatically.

The goal

Refine metals, unlock Ships, build a block ship with a cockpit, tank hydrogen from your electrolyzers, reach orbit and travel the system. Wrecks of the ISV Kassandra hide the story: find the logs.

Chemistry

Chemical plant: gas & liquid modes

Chemical plant: solid modes

Water purifier

Pulls dirty or contaminated water from an adjacent pipe/tank, outputs clean water (95 %), 600 W. The waste (mud, or uranium dust from contaminated water) collects as a solid: collect with E.

Power & the Reactor

The grid

• Cables connect machines to sources: they run in their own layer, so they can share cells with terrain.
• When demand exceeds supply, machines slow down proportionally (their status shows the power ratio).
• Batteries store 5 kWh each and smooth day/night cycles; research Superconductors to boost them.

Generation

Source	Power	Fuel	Notes
Solar panel	daylight-dependent	sunlight	free, but night and storms cut it
Generator	small	coal/wood	early game stopgap, makes CO₂
Gas generator	5 kW	methane / hydrogen / kerosene	pipe the fuel in; CH₄ and kerosene exhaust CO₂
Steam turbine	large	steam	pair with the reactor or any boiler

The uranium chain, end to end

1. Uranium ore: mine it (watch the ☢ dose) or purify contaminated water.
2. Concentrate: leaching plant (95 % yield, needs sulfuric acid) or crusher route.
3. Centrifuge (4 kW): each pass turns 5 % of the feed into enriched uranium, the rest exits as depleted uranium. Chain several centrifuges in a cascade: belt the enriched output of one into the next.
4. Fuel rod: craft in the assembler menu: 4 kg enriched uranium + 1 kg steel → 4 kg fuel cassette.
5. Reactor (2.8×2.8 m): load fuel rods. Produces ~2.4 MW of HEAT directly into its concrete core.
6. Cooling: run water pipes/tanks TOUCHING the reactor: they draw heat (3 kW per kelvin per neighbour), water boils to steam.
7. Steam → turbines → power. Condense or vent the exhaust.

Pipes, Fluids & Ventilation

PipeInsulated pipePumpGas pumpTankValve

Pipes and pumps

• Pipes carry liquids and gases between machines; the material you build them from sets their temperature tolerance (copper/iron/steel/aluminium/glass/brick/concrete).
• Insulated pipes keep hot fluids hot (steam!); radiant pipes deliberately shed heat: use them as radiators.
• Pumps push fluids from the world into pipes (place in liquid, LMB); gas pumps take from the top: park one next to a furnace chimney to capture CO₂.
• Tanks buffer fluids; valves gate flow and can be signal-controlled.

Ventilation

• Vents exchange air between inside and outside; the air purifier filters CO₂, toxins and radioactive dust with the right filter installed (HEPA / charcoal / lead-zeolite).
• Hot gases rise. Chimneys above furnaces + a capture pump beat scrubbing later.
• Watch the top-right air panel: pressure, O₂ share, temperature, toxins, dose. BREATHABLE means the helmet can open.

Boiling, freezing, phase changes

Every fluid has real transition points (see Materials): water boils to steam at 100 °C, freezes at -1 °C; steam condenses back; methane condenses at cryogenic temperatures. Machines and the world both respect these: your cooling loop can literally freeze solid on an ice world.

Ships

How to build a ship, step by step

1. Unlock Ships in the research tree, then press K (or Inventory → „Block ship") to open the ship builder.
2. Start with the Cockpit: it is the core of the ship (one per ship). Every other block must touch an existing block.
3. Lay the keel and hull. LMB places the selected block, RMB removes one (refunds 50 % of materials). Blocks cost materials from your backpack.
4. Mount Thrusters under the hull (nozzle down = main lift). R rotates the nozzle while placing: side nozzles give lateral thrust, up gives retro. Every thruster needs a straight exhaust path.
5. Add H₂ tanks, a Gyroscope (rotation), Landing gear (soft touchdown) and a Battery + Solar panel for onboard power.
6. Seal the interior: full shell of hull blocks + a Door (airlock). The game detects the hermetic interior automatically: install a Life support module with power and water and the inside fills with breathable air.
7. Fuel up: place a Refuelling coupling touching the hull; park the ship so the coupling touches a pipe, tank or electrolyzer with hydrogen: it pumps 0.5 kg/s into your tanks.
8. Board with E at the cockpit: the pilot sits down visibly at the console. Passengers board passenger seats the same way (co-op).

Flight controls

Land, sea and air vehicles

• Wheels drive on terrain using battery power: no fuel needed. More wheels = more force. Rovers and mining crawlers are ships too.
• Atmospheric rotors fly on electricity; thrust depends on air density: cheap planetary flight, useless in vacuum.
• Wooden hull + floats make boats: floats triple buoyancy; a paddle wheel or rotor propels them.

All 27 ship blocks

Block	Mass	Stats	Cost	What it does
Hull	120 kg		Steel plate 3 kg	Structural plate: connects blocks, provides collision, floats on water (buoyancy of 16×16 cells). 120 kg.
Cockpit	200 kg	200 Wh	Steel plate 4 kg Integrated circuit 1 kg Glass 2 kg	The ship's core: one per ship, start here. Seat, controls, camera. 200 kg.
Thruster	150 kg	thrust 9 kN	Steel plate 3 kg Electric motor 1 kg	Hydrogen rocket engine: 9 kN of thrust, 30 g H₂/s. Nozzle down = thrust up (W); sideways = manoeuvre (A/D); up = retro (S). [R] rotates while placing. 150 kg.
H₂ tank	90 kg	40 kg H₂	Steel plate 3 kg Steel 2 kg	40 kg of hydrogen per block. 90 kg empty.
Gyroscope	130 kg		Steel plate 2 kg Electric motor 1 kg Integrated circuit 1 kg	Reaction wheels: let you rotate the ship (Q/E) and stabilise flight. More gyros = faster rotation. 130 kg.
Landing leg	80 kg		Steel plate 2 kg Steel rod 2 kg	Damped landing leg: soft touchdown, stable parking, slow self-levelling. 80 kg.
Cargo hold	110 kg	cargo 1500 kg	Steel plate 4 kg Structural frame 1 kg	1500 kg of storage per block: [E] next to the ship opens the transfer panel. 110 kg empty.
Refuelling coupling	90 kg		Steel plate 2 kg Steel 1 kg Copper 1 kg	Fuel port: when the ship is parked and a pipe, tank or electrolyser with hydrogen sits below/next to the coupling, H₂ flows into the ship's tanks (0.5 kg/s). This is how you refuel from your own production.
Battery	180 kg	5000 Wh	Steel plate 2 kg Copper 3 kg Integrated circuit 1 kg	5 kWh of energy for gyros and the drill. Charged from solar panels. The cockpit has its own 200 Wh.
Solar panel	60 kg	600 W solar	Glass 3 kg Integrated circuit 1 kg Copper 1 kg	600 W in full sunlight (less at night/underground). Charges the ship's batteries.
Large thruster	400 kg	thrust 27 kN	Steel plate 8 kg Electric motor 3 kg Steel 4 kg	Large hydrogen engine: 27 kN of thrust, 90 g H₂/s. Heavy (400 kg), for big ships. [R] rotates the nozzle.
Mining drill	220 kg		Steel 4 kg Electric motor 2 kg Steel plate 2 kg	Mining ship: in flight LMB drills a 1.6×1.6 m area in front of the bit ([R] rotates it), the yield goes into the hold. Draws 1.5 kW from the battery.
Passenger seat	60 kg		Steel plate 1 kg Steel rod 1 kg	A place for a crew member (co-op: the second player boards with E at the seat and rides along). A crewed ship = seats + life-support module.
Life-support module	160 kg		Steel plate 3 kg Integrated circuit 2 kg Steel 2 kg	O₂ generator + CO₂ scrubber: the inside of a sealed hull (enclosed by blocks, doors shut) holds breathable air. Draws 300 W and 1 g of water/s from the hold.
Airlock (door)	50 kg		Steel plate 2 kg Electric motor 1 kg	Hull door: E next to it opens/closes. Shut = a wall (airtight), open = the interior loses its air.
Heavy armour	320 kg		Steel 4 kg Steel plate 2 kg	A thick steel plate: survives hard landings and impacts (block damage, v2.1). 320 kg.
Large hold	300 kg	cargo 4500 kg	Steel plate 8 kg Structural frame 3 kg Steel 2 kg	4500 kg of storage per block: for freighters. Unloaded through a coupling next to a crate.

Onboard generator	150 kg	2000 W	Steel plate 2 kg Electric motor 1 kg Copper 2 kg	Burns hydrogen from the tanks (0.05 g/s) → 2 kW into the battery. Power at night / underground for the drill, gyros and life support. 150 kg.
Water tank	120 kg	cargo 200 kg	Steel plate 3 kg Steel 2 kg	200 kg of water for life support and crew (the coupling loads water from a tank/pipe next to the ship; panel: "Water into the suit"). Without it, life support draws from the hold (50 kg).
Water and CO₂ recycler	160 kg		Steel plate 3 kg Integrated circuit 2 kg Copper 2 kg	Recovers water vapour and CO₂ from the cabin: life support uses 10× less water (+150 W). Long flights and base-ships without refilling water.
Fluid hold	220 kg	cargo 500 kg	Steel plate 5 kg Steel 4 kg	500 kg of liquid/gas (oil, water, oxygen, kerosene, acid…). Coupling next to a tank: LOAD mode takes from the tank, UNLOAD gives back (ship panel). Fluid transport between bases and planets.
Wooden hull	45 kg		Wood 6 kg	Planks on ribs: a light, cheap all-wood hull for boats and first vehicles. Floats better than steel (45 kg instead of 120 kg), but does NOT hold vacuum and burns in fire.
Drive wheel	70 kg		Steel plate 2 kg Electric motor 1 kg Steel rod 1 kg	WHEELED drive: drives over terrain on battery power (no rocket fuel). A/D to move, climbs slopes, brakes by itself. More wheels means more force, mining vehicles and rovers. On water it acts as a paddle wheel (slower).
Atmospheric rotor	120 kg		Steel plate 3 kg Electric motor 2 kg Integrated circuit 1 kg	ATMOSPHERIC drive: an electric propeller whose thrust depends on air density, cheap flight around a planet WITHOUT burning hydrogen. Useless in vacuum (rocket engines needed there). W/S up-down, A/D sideways.
Float (keel)	60 kg		Wood 4 kg Steel plate 1 kg	Buoyancy chamber: 3× more lift than a normal block and less rolling in waves. A wooden hull plus floats makes a boat; drive it with a paddle wheel or a rotor.
Ship furnace	300 kg		Steel 4 kg Steel plate 4 kg Integrated circuit 1 kg	The ship's electric furnace: smelts ores FROM THE CARGO HOLD (up to 1900 K, iron, copper, glass, silicon, steel); the product goes back to the hold. Ore reduction consumes coal/coke from the hold. 6 kW of ship power, 0.25 kg/s. The heart of a mobile base.
