AN INDEPENDENT SPACE PROGRAM SIMULATION
Build for
the beyond.
From the first bolt to another world.
Engineer your spacecraft. Fly the mission.
Build a space program of your own.
CAPTURE 001 / CAPE PADHelix Boomerang. Golden hour.Actual in-game scene · Interface hidden
01 / THE AMBITIONENGINEER. EXPLORE. REPEAT.
The launch is
only the beginning.
A spacecraft is one part of the mission.
A mission is one part of your program.
Design the vehicle, work out the trajectory, and bring your hardware home. Research, contracts and a growing fleet connect each flight to the next.
01 / BUILD
Give the mission a shape.
Choose the hardware. Plan the staging. Test the vehicle you assembled.
02 / FLY
Make every burn matter.
Work with orbits, maneuver nodes and mission plans, from departure to descent.
03 / GROW
Think beyond one launch.
Earn research, take on contracts and put a working fleet into space.
02 / FLIGHT ARCHIVEREAL SCENES. REAL SYSTEMS.
A universe to reach.
A program to build.
Selected scenes from the current development build, captured in-engine with carefully chosen viewpoints. Open any image for a closer look. Visuals and features are still evolving.
PACKHORSE FREIGHTER / PAYLOAD OPERATIONS
Built to carry
something extraordinary.
The large cargo bay opens to reveal the hardware inside. Two captures from the same orbital sequence, using the game’s bay controls.
THE DETAILS ARE THE GAME
Plan the burn.
Fly the plan.
A beautiful view is only part of the story. The map, maneuver controls and assembly bay put the decisions in your hands.

Flight notes.
How will I download the game?
Approved testers get a personal itch.io download key in the tester portal. Download the Windows ZIP, extract it completely, and run Play-Odyssey.cmd. No Steam purchase is required.
Will donating get me an invitation?
No. Support is optional and separate from tester selection. We want a manageable mix of experience levels and PC hardware.
What PC will I need?
See the provisional requirements above. These are estimates for this alpha, not validated minimums or a frame-rate guarantee.
How unfinished is the alpha?
Expect changing features, bugs and possible save resets. The first-session guide will cover creating a company, trying early missions, and saving and resuming. Each release will state save compatibility.
Are applications open?
Yes. Apply free, then check your tester portal for a decision. A maximum of 100 testers can be approved. An application or donation does not guarantee an invitation.
