Pre-Alpha 1.00 Almost here PLANEX Roblox

Every star is a solar system. Every solar system has worlds.

A procedurally generated space exploration and survival game on Roblox, rebuilt from the ground up. Leave the surface, cross the void and find what's waiting out there. The first playable pre-alpha is almost here.

Pre-Alpha 1.00 is almost here

PLANEX has been completely rebuilt with a new foundation, new worlds and a new look, and the first playable pre-alpha is nearly ready. The exact date and access details drop on Discord first.

The pre-alpha is the first playable step, not the finished game. Expect rough edges, missing systems and fast, frequent changes, and help us shape what comes next.

Built to be explored

Star systems, planets and moons are generated procedurally, so every system you visit is its own place with its own conditions.

Every star is a solar system

Each star anchors its own system of orbiting planets, moons and belts. Pull up the system map to see the whole thing: orbits, bodies and where you're headed next.

Step off the edge of the world

With true simulated atmospheric scattering, leave the ground behind and climb until the horizon curves away, then keep going into open space. Navigation markers track planets and their distance, so the next world is always a destination, not just scenery.

Every surface has conditions

Your suit reads the world around you: surface temperature, local time and which body you're standing on. Night on Aetuke-d drops well below −100 °C, and survival starts with knowing where you are.

Always know where you are

Zoom from a whole system down to a single moon. Orbits, bodies and your own position are mapped live, so you can plan the route before you commit to the jump.

Infinite worlds. Here are three.

The universe is procedurally generated and never runs out. These are just snapshots of places we stopped on the way, with the readings the suit gave at the time. Every star you fly to has worlds of its own.

  • Rolling dunes on Aetuke-b glowing orange under a low sun

    Aetuke-b

    Surface 68.90 °C, local time 17:57, uID 98911-2

    Dunes as far as the horizon. Close to sunset, the ground still reads almost 69 °C.

  • An astronaut on Aetuke-c looks up at the galactic band over a line of trees

    Aetuke-c

    Surface 160.59 °F, local time 20:20, uID 98911-3

    An ocean world with forested coastlines. Its nights open onto a sky full of stars.

  • The blue world Alce-d seen from orbit with a small red moon nearby

    Alce-d

    Observed from orbit, one red companion moon, uID 49230-4

    A blue world in a different system entirely, shadowed by a rust-red moon.

You begin with nothing.
The universe begins everywhere.

Awaken stranded with a damaged exosuit and a ship that won't fly. Your first objective: survive. From there, gather resources, craft new technology and rebuild your hyperdrive to take to the stars.

Build bases, trade with other explorers, chase anomalies through the void, and team up with friends to make your mark on the galaxy. That's where PLANEX is headed, and the pre-alpha is the first step.

Skies worth flying through

Volumetric clouds are the next big step for planetary atmospheres. These shots come from our cloud prototypes and show the visual direction we're aiming for.

Not in pre-alpha Volumetric clouds are still being built and are not part of the Pre-Alpha 1.00 build. Images below are a visual target, not current gameplay.

Where development stands

A rough picture of what's in the rebuilt game today and what's still ahead. Priorities shift as we build.

In development

A next-gen planet system

Roblox terrain can't take PLANEX where it needs to go, so planets are moving to Editable Meshes for full control over every world. A floating origin keeps huge solar systems stable, and viewport rendering draws distant planets in the sky.

  • 50,000 studs Planet size, up from 750. Planets that feel like planets.
  • No loading screens Generation is close to instant, so you never wait to explore.
  • Real-time orbits Planets circle their sun and moons circle their planets as you play.

Frequently asked questions

When does the pre-alpha release?

Very soon. Pre-Alpha 1.00 is almost here, and the exact date and access details will be announced on our Discord first. Joining the Roblox community is the best way to be ready on day one. The pre-alpha is the first playable step; the full game is still being built.

What does "rebuilt" mean? Is this the same game?

PLANEX has been rebuilt from the ground up: new world generation, new visuals and a new foundation for everything that comes next. Everything on this site shows the rebuilt version.

Are the volumetric clouds in the pre-alpha?

No. Volumetric clouds are in development and are not part of the Pre-Alpha 1.00 build. The cloud images on this site come from prototypes and show the visual direction we're working toward.

What should I expect from a pre-alpha?

An early, evolving build. Some systems from the long-term vision, like crafting, bases and trading, won't be there yet, and you'll likely run into bugs. Your feedback on Discord directly shapes what we build next.

What platforms will PLANEX be on?

PLANEX is being built exclusively for Roblox, which runs on PC, mobile and console.

Will there be multiplayer?

Yes. PLANEX is designed with multiplayer in mind. The long-term goal is for you to team up with friends to explore planetary systems and form factions across the galaxy.

How can I support development?

Join the community, share feedback, and if you'd like to support the project directly, you can do so on Patreon.
