World Builder
Make a whole world without writing code: terrain, buildings, rules and all.
Create
Build what doesn't exist.
NEXUS is meant to be built by the people in it. It starts small: an island that's yours, parts you can place anywhere, and a scripting language that makes them come alive.
Available now
Your Pocket is your first world.
Walk through the mint portal in the plaza and you're on your own floating island. Press G to open Build Mode.
- Build ModePlace, move, turn and resize parts. Change colors, glow and opacity. Undo anything.
- Spark scriptingPlain-word scripts that react when something is touched, clicked or started. Move parts, launch players, play sounds, keep score.
- Safe by designSpark can't create Flux, items or XP, and loops that never pause get stopped. Scripts only touch their own Pocket.

Coming later
The creator era.
This is where NEXUS is going. None of it is in the game yet, and we'll say so plainly until it is.
Describe it, then shape it
Say what you want ("a three-story club with a rooftop pool") and get a starting point to edit by hand.
Portals between worlds
Link your world to others. Your avatar, collection and reputation go wherever you go.
Friends in your Pocket
Invite people to see what you've built, and let your scripts run for them too.
Tools for pros
Deeper scripting and editing for experienced creators, on the same platform as everyone else.
Creator profiles
A reputation built from what you make and who visits it, not from follower counts.
Technology
Built on NEXUS ENGINE.
NEXUS runs on its own engine, written in C++ for this one job: persistent, shared worlds that anyone can build in. No commercial engine sits underneath, so nothing outside NEXUS decides what worlds can become.
Both the Mac and Windows apps run on NEXUS ENGINE today, and every change is built and tested on Windows automatically.
Frame time, NEXUS CITY6.8 msGPU time at 1440p, high settings, on an M1 Mac.
Automated engine tests84Run on every change, with memory and thread checkers.
InsideRendering, physics, audio, UI, networkingPlus a job system and an entity system built for big shared worlds.
Your island is waiting.
