Nine systems · one factory

every system feeds the next
module

Tent farm

Raise the trailers, stockyards and fabrication tents that turn an empty patch of dirt into a launch site.

module

Machines

Order, assemble and deploy CNC mills, welders and avionics rigs. Keep them running before they break.

module

Parts pipeline

Queue recipes, fabricate, stockpile, inspect. Quality scores carry forward into vehicle assembly.

module

Research tree

Spend headcount-days on R&D nodes that gate new tents, machines, parts and vehicle types.

module

Testing

Part inspections, system fires and full-stack hops. Every test can pass, fail, or destroy your prototype.

module

Crew

Engineers, technicians and operators draw salaries every day. Headcount unlocks throughput — and burns cash.

module

Outsource

Skip the factory floor. Pay a premium to receive ready-made parts on a delay, when you need to bridge a gap.

module

Contracts

Tracked tasks pay out cash, unlock research, and pull you toward the next milestone.

module

Vehicles

Static fire, then hop. Survive a 150 m hop and you have shipped your first Starhopper.

Core loop

a day in the life
  1. 01 · plan

    Read your cash burn, queued parts, and contract list. Decide whether the day is for spending or shipping.

  2. 02 · build

    Drop tents, box machines, hire crew, queue research, kick off a test, sign an outsource order.

  3. 03 · end day

    Salaries pay out, fabrication ticks down, tests resolve, research advances, methane boils off.

  4. 04 · log

    A condensed mission log records what happened. Adjust, repeat, and push toward the next vehicle.

Briefing

faq
Do I need an account?
No. Your save lives in this browser, signed and synced to the cloud against a per-device ID.
Can I lose?
Yes. Run cash to zero with no income, or destroy enough vehicles, and the run ends.
Is there an end?
Right now the goal is the first 150 m hop. Past that, the sandbox is yours to optimize.
Can I play on mobile?
Yes. The HUD reflows for small screens and the canvas supports touch.
