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.
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
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.
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.
I've seen sexier pigs. Game runs like piss
Horrible performance, totally pointless and extremely complicated to handle. Quite frankly, it is easier to learn how to develop a game than it is how to play this game - and that is even once you accepted the fate that there is absolutely no point to this game. You can model your space station and look at it. That is it. And yes: you can bring in your characters and let them do some erotic stuff. The result? You go: Mehh...this is what I wasted all my time watching tutorials for so I can set-up this kind of scene? And then that is all it is: One static scene to watch. That is it.
If you would like to dump 5-100 dollars on an almost completley non-functional porn game/ space game this is it. If you want to have fun go practically anywere else.
This game crashes more than a blind race car driver. The character models are so stiff and buggy that they make Garry's Mod look like a triple A game.
absolutely love this game. There is a solid progression in updates. This is one of those games you can spend forever in and lose all track of time. If you love space, building stuff and playing with characters then look no further than this game!!!!
Well, pretty specific game for specific people - if you tired of shooters and strategy games can entertain you a lot.
I really wanted to like this but the base game is empty without the DLC's! Base game should be f2p imo.
