Version 10, now known simply as Garry's Mod, has been available for purchase on Steam since November 29, 2006. An older, unsupported version, 9.0.4, is available as a free download at, and is also available from Steam free of charge. The current version of Garry's Mod is version 13, which still receives regular updates via Steam. Some even choose to remain in the sandbox mode to construct contraptions or scenery with the props and maps from most of Valve's games. Many different gamemodes have emerged with many different objectives and styles. Being a sandbox type game there is no goal as such or a way to win, rather users are able to modify the game and play the mod however they wish.
It allows the player to manipulate objects and experiment with the physics of the Source engine, often with interesting results due to the power of the engine.
Garry's Mod, or GMod for short, is a sandbox modification for Half-Life 2.
