About This Game

Astrobuilder is the world’s first dynamic world RPG where every character is playable and no story ever repeats.

Set in the collapsing Neon River galaxy, you don’t just shape the world—you live as part of it. Switch identities, trade across stars, forge alliances, and trigger quests born from an evolving simulation of 600+ thinking NPCs.

In this galaxy, you’re not the only one making choices. The world reacts. The world remembers. And it moves—with or without you.

One empire and four rising factions—Mogel, Patti, Nami, and the Reefs—threaten the last bastion of civilization: the Star of Reason.

Lead your guild of wanderers to restore shattered planets, reopen lost trade routes, and breathe life back into a fractured galaxy.

Every NPC is more than background—they have goals, memories, and the power to act.

They form alliances, hold grudges, change identities… and so can you. Every journey unfolds with new storylines, quests, and consequences, all shaped by the simulation itself.

Built on deeply integrated AI, Astrobuilder turns systems into storytellers:

🌌 Global narrative evolves from your actions and world events

🧠 NPC dialogue, quests, and events are generated in real time

📱 In-game mobile system lets you call, chat, and even unlock personal missions

🎭 Procedural quests and puzzles offer limitless outcomes

No scripts. No loops. Just an ever-changing galaxy that adapts to how you play.

Planets are living simulations—dynamic economies, unstable politics, endless rebuilding.

Strategize your next move or dive into the unknown: production chains, planetary upgrades, and factional chaos shift every time you play.

No humans. No clichés.

From sentient sharks to striped tigers and rogue machines, Astrobuilder offers a warm, expressive cartoon style wrapped around a universe of wild species and unforgettable characters.

The Neon River Is Breaking. Who Will You Become?

Will you lead the revival? Or exploit the collapse?

Will you stay true to your path… or switch sides when it matters most?

Your story isn’t written. In this galaxy, you write it yourself.
