Make a game by typing a sentence — then play it on your own PC with Lumen real-time lighting (and RTX ray tracing on supported cards). One small download, and every game you build streams straight in. No engine to install per game, no setup.
322 MB · Windows 10 & 11 (64-bit) · Version 1.8.0-beta · ONE app: chat with BIT AI on the left, your game plays on the right
New in 1.8.0-beta — the app is a real editor now: it opens to a home screen with your games — play your latest, jump back into any recent one, or start a new build with BIT — instead of dropping you straight into the last thing you played. And it always opens: a game with a broken update can no longer stop the app from starting (it gets set aside and repaired while you play something else). Plus everything from before: your game always hears your keys, rock-solid model streaming (a broken 3D model can never crash the app), a film-style camera, the cinematic kit (particle effects, live weather, a moving sun, instanced forests, real music), all under Lumen real-time lighting (RTX ray tracing on supported cards).
The desktop app is in beta — sign in and build a game first, then your creations stream straight into the app. An internet connection is required.
Two different Windows downloads, by the way: this page is the Desktop Studio & Player — one installed app that streams your whole library (internet required). Separately, on the Studio plan you can export one game as its own standalone .exe from the Studio's Download menu — a single file you can send to anyone, no install, playable offline.

System requirements
Because ARCADEBOX.AI games use clean, lightweight 3D, the real-world floor is far lower than a typical big game — an everyday laptop runs it.

Any 64-bit dual-core from roughly the last 8 years
Modern quad-core (Intel Core i5 / AMD Ryzen 5, 2020 or newer)

What you're installing
A 363 MB download (about 530 MB installed) that never grows per game — every game you make loads into the same app.
Lumen real-time lighting — bounced light, true soft shadows, RTX ray tracing on supported cards
Every game you build streams in and hot-loads in seconds
Games that fix themselves — a broken build heals automatically
Installs just for you — no admin prompt, clean one-click uninstall
No bundled junk, no background services, no ads or behavioural analytics — the Player connects to ARCADEBOX.AI only to sign in, stream your games, and send the technical error reports that power self-repair
Your library and settings survive reinstalls
How to install
Click Download for Windows above and save the installer.
Open the downloaded AB-Unreal-Editor-Setup file.
Windows may show a blue "Windows protected your PC" box — that's normal for a new app during our beta. Click More info → Run anyway.
Follow the installer, then launch AB Unreal Editor from your Start menu or desktop.
Build a game in the Studio, pick the desktop engine, and it opens straight in your Player.
Why the warning? The beta isn't code-signed yet (a signed version is coming for the public launch). The installer is per-user only: it never asks for administrator access, adds no services, and uninstalls cleanly from Add or remove programs.
User guide
Everything you make in the Studio can run in the desktop Player. Here's the whole loop.
Install once. Grab the Player above and run the installer — one app, no per-game setup.
Build in the Studio. Describe your game, and pick the Cinematic 3D (desktop) engine when you want the premium look.
Play on your PC. Your game streams into the Player and loads in seconds — no re-install, no export. Every new game and every edit hot-loads into the same app.
It fixes itself. If a game hits an error, the Player sends it to BIT AI, which patches it and reloads the fixed version automatically.
Controls
Move — WASD or the left stick
Aim / look — mouse or the right stick
Fire — left mouse or Space
