About This Game

Build. Launch. Land on the Moon.

The yard runs a night shift. You are a robot with a build deck, a pair of welding arms and a professional opinion about rockets. Everything in the scrap piles is yours if you can carry it: rocket motors, thruster bells, fuel barrels, a leaf blower, a water heater, and a fridge that will absolutely serve as a capsule.

The Moon is 384,400 km up. Somebody has to go.

Weld first, regret later

Weld the junk together and the build readout grades your rocket before it leaves: integrity, thrust, efficiency, and a short, frank verdict. The physics believes the welds, not your optimism. A rocket that looks assembled is assembled. Briefly.

Every few minutes a supply crate comes down on a parachute with a Rocket Motor inside. Everyone in the yard sees where it lands.

The launch is a ceremony

Lock the build and your rocket goes onto the shared launch pad in the middle of the yard. Hit the big red button and the whole yard hears the range-clear call. Then watch your junk climb off a very small planet. The altitude board keeps the score, rung by rung, from "Above the junk piles" to the Moon.

Most rockets veer, corkscrew, flop or come apart. Whatever comes down rains back into the yard as salvage. Try again. The shift is not over.

Your crewmates are the hazard

Online co-op for 1–4 players through Steam, with Mac and PC in the same yard.

• Build your own rocket, or join someone else's as crew and share the credit for wherever it ends up.
  
• Shoot the parts right out of a rival's pockets. They rain back into the yard as salvage.
  
• Text chat and proximity voice, with per-player mute.
  
• The end-of-shift board hands out YARD AWARDS (LAWN DART, SIDEWAYS ENTHUSIAST, YARD SALE). It is right about you.

Four robots, one job

• RIVET, hero scavenger. Employee of the month, four years running. Sole applicant.
  
• GANTRY, crane bot. Used to lift shipping containers. Does not discuss it.
  
• DOZER, treaded tank. Has never reversed. Sees no reason to start.
  
• SPARK, monowheel. One wheel, no regrets. Balance is a lifestyle.

They all move, jump and reach the same. They disagree about everything else.

On the record

• 37 Steam achievements.
  
• Two world leaderboards: highest flight, and fastest trip to the Moon. A sign in the yard reads them out.

Free demo

The free demo has the whole yard, all four robots and online co-op. It ends at space: get a rocket past the Kármán line, 100 km up. Shifts are 8 minutes and the demo gives you 90 minutes of play. The Moon is in the full game.

There is also a raccoon. It does not help.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Junkyard Astronauts was developed with substantial help from an AI coding assistant (Claude), directed and reviewed by the developer. Specifically: the game's code was largely written with AI assistance; the 3D models, textures and yard layouts are produced by procedural generator scripts written with AI assistance; the sound effects are built from licensed, human-recorded sound libraries (Sonniss GDC bundles, Kenney) assembled and mixed by scripted tools written with AI assistance; the soundtrack is composed and rendered by a music engine written with AI assistance; parts of the store text and the achievement names were drafted with AI assistance. Everything was reviewed, edited and play-tested by the developer before shipping. No AI service is used during gameplay, and no content is generated at runtime. No AI-generated content imitates a real person or a third party's protected work.
