About s&box

s&box is a versatile game creation platform built on Valve’s powerful Source 2 engine, serving as a spiritual successor to Garry’s Mod. It offers players access to hundreds of community-made games spanning shooters, roleplay, racing, platformers, horror, and genres yet to be defined. With no installation or subscription required, users can instantly jump into games and party up with friends without the hassle of server setup. This seamless multiplayer experience allows for spontaneous fun and exploration within a constantly expanding library of diverse content. The platform also supports rich customization options, enabling players to personalize their avatars with cosmetics that carry across every game they play. For creators, s&box provides an intuitive modern editor featuring a standard scene system and a robust C# API with powerful hotloading capabilities. Anyone can design, build, and publish games directly to the platform, making sharing effortless and immediate. Developers can earn revenue through the Play Fund, which distributes earnings based on player engagement funded by cosmetic purchases. In addition, an upcoming feature will allow creators to publish their games as standalone titles on Steam without engine royalties. Regular content updates keep the platform fresh and evolving, fostering a vibrant community where both players and developers thrive in a dynamic sandbox environment.
