About This Game

Welcome to Sci-Fi Builder — a third-person sandbox sim where the galaxy said, “Go wild,” and you said, “Hold my cosmic wrench.”

You’re the head honcho of a totally empty space station on Planet 1188 in the Centurion Constellation. It’s cold, lonely, and dangerously lacking in funky wall art. Your job? Turn this metallic void into a thriving colony full of humanoids, aliens, robots, and whatever else your brain can invent at 3 AM.

🛸 So what do you actually do?

Everything. Absolutely everything.

  • Design sci-fi rooms with no grid snapping (yes, true freedom!)

  • Place and move furniture like a chaotic space god

  • Repaint your station until it glows like a synthwave album cover

  • Control lighting like you're hosting the Galaxy’s Got Talent

  • Teleport NPCs like a teleportation-happy wizard

  • Set up interactions between creatures, robots, props, or your own character

  • Accidentally create alien soap operas and robot dance battles

  • Build a full society, then give everyone very questionable jobs

🤖 Characters? You bet.

Choose from hundreds of beings: humanoids, strange creatures, moody robots — even the weird guy from Engineering. You can control them, dress them up, make them interact, or just watch them do very unexpected things in the cafeteria.

📦 What’s in the toolbox?

  • Space furniture, devices, computers, construction parts

  • Custom color settings for everything from walls to alien shoes

  • Sounded rooms with interactive actions

  • Full wardrobe customization

  • NPC personality settings (will your robot be flirty or feral?)

  • No object limits — if your station starts lagging, that’s on you

🚀Bottom line:
Sci-Fi Builder is what happens when creative freedom, sandbox chaos, and sci-fi dreams collide.
There are no rules, no real endgame — just infinite possibilities, alien fashion shows, and maybe a toilet in zero gravity.

So suit up, space architect — your station needs... whatever this is.
