Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“PrimeCraft is a living sandbox built around procedural planets, local on-device AI companions, and user-generated scenes. The core simulation already works, but the scale of the multiverse and the depth of AI interactions grow stronger when real players experiment, explore, and give feedback.

Early Access lets me refine the controls, expand the toolsets, and improve AI behavior based on how players actually use the sandbox. Because PrimeCraft mixes physics, exploration, and real-time trained AI, it benefits hugely from community input while the systems are still flexible and evolving.”

Approximately how long will this game be in Early Access?

“The plan is to remain in Early Access for several months, potentially up to a year, depending on how quickly core features mature and how much feedback comes in. The timeline is flexible because the game expands through player interaction, new tools, and AI improvements.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to include:

- Additional biomes, planet types, and galaxy structures

- More AI companion abilities and behavior modules

- Expanded couch-co-op and online interactions

- More tools for building, importing, and sharing scenes

- Improved physics events, lasso upgrades, and traversal mechanics

- More customization options

- Better onboarding and tutorials

- Polished UI/UX, accessibility improvements, and bug fixes

The goal is to grow PrimeCraft into a rich physics playground where exploration, AI behaviour, and player creativity all feed into each other. These are plans, not guarantees, but they reflect the intended scope for full release.”

What is the current state of the Early Access version?

“PrimeCraft is fully playable and stable, with:

- Planet-to-planet traversal across billions of procedural worlds

- Local on-device AI training and AI companion behavior

- Lasso physics, teleportation, and movement tools

- Importing and exploring player-made scenes

- Couch co-op support for local multiplayer

- Save/loading improvements, persistent AI training, and fixed planet seeding for long-distance travel

- Updated UI for music, AI management, and scene loading

Early Access players can explore, train AI companions, experiment with scenes, and test new traversal and physics systems as they evolve. Some features are minimal, experimental, or still being expanded.”

Will the game be priced differently during and after Early Access?

“The plan is to keep the price stable during Early Access. The price may increase slightly when the game leaves Early Access, depending on how much new content, AI features, and tooling are added. But there are no firm promises yet.”

How are you planning on involving the Community in your development process?

“Players can get involved by:

- Sharing feedback on movement, controls, and traversal

- Suggesting new planet types, tools, and physics interactions

- Testing AI companion behavior and reporting weird or fun emergent results

- Uploading and exploring shared scenes

- Posting bug reports, feature requests, and balance notes

- Participating in small community experiments to help refine AI interactions

PrimeCraft evolves fastest when players experiment inside the multiverse and show what works, what breaks, and what inspires new ideas.”

About This Game

PrimeCraft is a sci-fi sandbox about exploring a vast, procedurally generated universe of miniature planets, training AI companions, and jumping into handcrafted scenes created by the community. Every world you visit has its own gravity, terrain, and strange little challenges, and you’re free to roam, experiment, or simply relax and explore.

Travel between billions of unique planets, drop into “bubble” scenes for small self-contained experiences, and return seamlessly to open-world exploration. Play solo or bring friends along in multiplayer and local split-screen modes.

Your AI companion learns directly from your actions. Teach it how to move, navigate worlds, help you, or take your place entirely inside any scene. AI behaviour persists across worlds and sessions, creating a growing sense of personality as you explore.

PrimeCraft is built around playfulness, physics, and discovery. Whether you’re drifting between planets, testing a new AI reflex, or showing friends a strange world you found, the universe is designed to surprise you.

Key Features

Billions of unique planets — Procedurally generated worlds with dynamic gravity and seamless travel.
AI companions that learn from you — Train behaviours in real time and let them assist you or take over.
Jump into “bubble” scenes — Load custom levels, puzzles, experiments, or mini-scenarios created by players.
Singleplayer, co-op, online co-op, and split-screen — Explore together across multiple modes.
Physics-driven sandbox — Lasso objects, teleport, bounce, glide, and experiment with playful mechanics.
Stylized 3D universe — Colorful, atmospheric worlds designed for wandering and curiosity.
Ongoing updates — New biomes, tools, AI features, and scenes will be added throughout Early Access.
