s&box is a Source 2 powered game creation sandbox from the creators of Garry’s Mod, which allows users to create and share games in an easily accessible community-focused way.
A spiritual successor to Garry’s Mod (not a sequel), s&box aims to eclipse what’s possible in Garry’s Mod rather than just update it. It’s a little like a blend of Garry’s Mod, Dreams and Roblox, and has diverse and easily accessible tools that allow users to create, play and share a vast variety of different types of games – from online multiplayer shooters, to racing games, platformers and puzzle games.
s&box features cloud assets, multiplayer built into the engine, hotloading (which allows you to see changes you make without restarting the game), Valve’s Hammer Editor, a terrain system that allows you to create huge open worlds, visual scripting and VR support. All in all it’s a very easily accessible way to experiment with game development and there are even plans for devs to earn money from their creations.
To join the s&box Developer Preview you need to visit the s&box website and click the Steam “Log in” button in the top-right of the screen. s&box will be added to your Steam account and you’ll be able to download it on Steam.
