Cloud Cruiser Guide: Systems, Power & Lift
Keep your ATMOSFAR Cloud Cruiser flying: reactor cores, power units, hydrogen fuel, balloons, cargo lift, and cruise control in one practical guide.
What the ATMOSFAR Cloud Cruiser Really Is
The ATMOSFAR Cloud Cruiser is not a vehicle you hop into and drive — it is a flying base you keep alive. Every system feeds another: the reactor makes electricity, the electricity chills the fuel tanks, the fuel drives the thrust, and the balloons decide whether any of it stays in the sky. Change one small thing, like bolting in an extra machine, and you can quietly break a basic function somewhere else on the ship.
That interdependence is the whole point. The ATMOSFAR Cloud Cruiser serves as your mobile base of exploration, far larger than a Wasp and seriously customizable, so you can shape it around whatever job you are doing. It is also slow. Plan around endurance and logistics rather than speed, and you will spend far less time drifting toward an island you did not want to meet.
| System | Role on board | Planning note |
|---|---|---|
| Nuclear reactor | Central power plant for almost every module | Cores are limited and difficult to transport |
| Cargo lift | Rooftop aperture plus conveyors for oversized cargo | The only practical way to load a reactor core |
| Thrust system | Pushes the ship forward | Runs on hydrogen, not electricity |
| Hydrogen refinery | Turns hydrogen crystals into liquid fuel | High yield, heavy planning and hauling |
| Hydrogen siphon | Pulls hydrogen from the air | Passive fuel gain, but it draws power |
| Balloons | Keep the hull and its cargo aloft | Lift is a weight-to-balloon calculation |
| Helm and periscope | Steering plus cruise-control waypoints | A missing periscope can be built |
Mechanics described for the ship are still subject to change before release, so verify numbers in-game once you are aboard.
Nuclear Cores and the Cargo Lift
Almost everything inside the hull runs off a nuclear reactor, and reactors need cores. Cores are scarce on Tycos, assembled long ago and now scattered — some hidden, many lost in the wreckage of crashed ships. That scarcity shapes your whole early game: before you can plan a build, you need to plan a recovery.
A Scout Wasp's Geiger counter is the practical search tool for finding a core in wreckage. Once found, the harder problem starts. A single core weighs several hundred kilos, cannot be lifted by hand, and emits radiation heavy enough that a suit only buys you time, not safety. Handle it quickly, calmly, and never let it drop — a damaged core can detonate.
| Step | Action | Why it matters |
|---|---|---|
| 1 | Scout wreck sites with a Scout Wasp | Its Geiger counter flags radioactive cores |
| 2 | Bring a Cargo Wasp and fly it confidently | Nothing else moves a several-hundred-kilo core |
| 3 | Keep your exposure short | Suits do not fully stop core radiation |
| 4 | Hover the Cargo Wasp over the cargo lift | The rooftop aperture opens automatically on approach |
| 5 | Let the conveyors take it | The core will not fit through a normal door |
The cargo lift is the answer to the "it doesn't fit" problem. It sits at the top center of the ship, opens when a Cargo Wasp gets close, and feeds cargo onto conveyor belts that carry it to storage. The same mechanism runs in reverse to eject bulky scrap — useful when you need to shed weight in a hurry. Reading how the nuclear reactor core powers the vessel makes the lift's priority obvious: without a core, nothing else on your build list matters.
Power Units: Balancing the Electrical Budget
Power is tracked in Power Units, brokered every second — produced by reactors, consumed by modules. Everything except the thrust system draws PU, so your job is to keep total draw under total output at all times.
The scale is easy to underestimate. A single reactor producing 25 PU sustains 25 modules that each draw 1 PU, and nothing more. Add a second reactor and you get 50 PU — but only if you have another core plus the building materials for the reactor itself. Expanding output is never a free fix.
| PU concept | What it means in practice |
|---|---|
| PU is a per-second rate | Compare production against draw over time, not in totals |
| One reactor at 25 PU | Matches roughly 25 modules drawing 1 PU each, with nothing spare |
| Two reactors at 50 PU | Doubles output, if cores and materials allow |
| Thrust is exempt | Fuel burn sits outside your electrical budget |
| Tank cooling draws PU | Cut the power and stored fuel starts evaporating |
Two rules keep you out of trouble. First, never let a single module eat a large share of your output — spreading draw across many small consumers is safer than one hungry machine. Second, treat fuel-tank cooling as critical infrastructure, because liquid hydrogen has to stay below -253°C (-423°F). Lose power to the cooling system and your reserves quietly boil away.
Fuel, Thrust, and the Hydrogen Loop
The thrust system is the one major component that burns fuel instead of electricity. More thrust means more speed, and more speed means faster consumption, so a slow cruise is your cheapest way to travel. You are not defenseless about supply, though — the ship can generate its own hydrogen in two ways.
| Option | Fuel source | Effort | Yield | Power draw |
|---|---|---|---|---|
| Hydrogen refinery | Hydrogen crystals hauled from islands by Cargo Wasp | High: mining, hauling, routing | High | Yes |
| Hydrogen siphon | Hydrogen pulled from the surrounding air | Low once installed | Steady and passive | Yes |
Refineries reward planning. You fly to a crystal deposit, haul it back with a Cargo Wasp, feed the refinery, and store the liquid hydrogen in tanks. Siphons reward patience: mount them on the exterior and they trickle fuel in continuously, which makes them excellent for topping off between long hauls and for filling balloons. Many crews run both — siphons for baseline supply, refineries for big pushes.
Keep the customizable aerial base's thrust low when you are not in a hurry. A slower setting costs you minutes; a drained tank costs you a rescue trip.
Balloons, Weight, and Piloting the Beast
How lift actually works
The Cloud Cruiser is metal and plastic, with no hydrogen of its own, so it floats on balloons filled from the air by a siphon. Lift is therefore a straight relationship between total weight and balloon count. Install a heavy machine or load dense cargo and you must add balloons to compensate.
Weight does a second job too: a heavier ship needs more thrust to get moving. So every kilogram you carry taxes you twice, once in lift and once in fuel. Override the maximum weight capacity and an alarm will blare without stopping until you either add balloons or remove mass.
| Symptom | Likely cause | Fix |
|---|---|---|
| Alarm that will not silence | Max weight capacity exceeded | Add balloons or eject cargo via the lift |
| Ship drifting lower after a build | New heavy modules added | Add balloons |
| Sluggish, unresponsive movement | High mass against current thrust | Shed weight or raise thrust and accept fuel burn |
| Fuel vanishing while parked | Reactor or PU shortage killed tank cooling | Restore power production |
Helm, periscope, and cruise control
Navigation happens at the helm, usually placed on top or at the front for the best view. From there you thrust, reverse, and turn. Because the ship needs constant maintenance, you cannot stay glued to the controls, so it carries cruise control. Mark a navigation point through the periscope and the ship calculates the route itself.
Two caveats. Obstructions such as pieces of floating islands may force you to reposition manually before the route works. And the hull carries serious inertia, so start turns early — this thing does not pivot.
First-flight checklist
- Confirm a reactor is installed and producing more PU than the ship consumes.
- Fill the fuel tanks and check the cooling system has power.
- Count balloons against your current cargo and machine load.
- Confirm a siphon is feeding the balloons.
- Mark your first navigation point at the periscope, then engage cruise control.
- Fly with a squad if you can. Solo operation is possible, but managing interdependent systems alone is a rough start for a new Vagabond.
FAQ
Can I pilot the ATMOSFAR Cloud Cruiser alone? Yes, technically. It is buildable, pilotable, and manageable solo, but the systems are tightly connected and a single miscalculation ripples through the ship. Bringing squadmates is the recommended path while you learn.
What actually powers the Cloud Cruiser? Almost everything runs on electricity from a nuclear reactor, measured in Power Units per second. The thrust system is the lone major exception and burns liquid hydrogen.
How do I load a nuclear core into the ship? Use a Cargo Wasp to carry it to the rooftop cargo lift. The aperture opens as the Wasp approaches, and conveyors move the core to storage. Keep the trip short and never drop the core.
Why is my ATMOSFAR Cloud Cruiser sinking or losing fuel? Sinking points to excess weight against too few balloons. Fuel loss usually means the tanks lost cooling power, so check reactor output and total PU draw before you blame the siphons.
