S&box is a game creation platform built on Valve's Source 2 engine.

Play, create, and share games, explore community creations, and experience endless sandbox fun with powerful modern tools.

Play

Hundreds of games made by the community - shooters, roleplay, racing, platformers, horror, and stuff we don't even have a name for yet. No installing or subscribing, just click to play. Party up with your friends and they can play too, no need to mess around setting up servers.

Create

Anyone can create games using our intuitive modern editor, creating scenes with a standard scene system and a C# API with powerful hotloading.

Share

You can publish your games directly to the platform where everyone can play it at the click of a button.

You can earn through our Play Fund from players playing your games, directly funded from cosmetic purchases.

Or (coming soon...) you can take it one step further and publish to Steam as a standalone title, with no engine royalties.
