Garry's Mod

A sandbox game built on the Source engine, developed by Facepunch Studios under the direction of Garry Newman and published by Valve. The game offers players unprecedented freedom to create their own scenarios, structures, and game modes using assets and mechanics from Half-Life 2 and other Source-based games. Unlike traditional games, it has no predefined objectives or missions—players can build intricate contraptions, design mini-games, simulate scenes, or simply experiment with physics. Over time, the community has developed numerous custom game modes, including DarkRP, Trouble in Terrorist Town, and Prop Hunt, transforming Garry's Mod into a full-fledged multiplayer entertainment platform. Its extensive modding capabilities and Steam Workshop support allow for endless content creation and sharing, making it one of the most versatile and long-lasting sandbox experiences in gaming history.
