Garry's Mod (previously known as GMod 10) is the first commercial iteration of the mod. GMod 9 is the last free version of the modification, and was last updated to version 9.0.4 on the 27th of November 2005. GMod can be used as a map editing tool that interfaces with Valve Software's proprietary editor Hammer to add furniture and small items through its first person interface, letting users graphically interact with their map. As mentioned, this has allowed an extensive community to build up and create other mods and mini-games to distribute within the built-in workshop function in GMod'. While GMod does not possess any actual gameplay value in a traditional sense, it enables the player to freely manipulate all of the objects and features of the Source engine except for the background features.


Garry's Mod is a game modification, created by Garry Newman in 2004, and a successor to JBMod, the original sandbox Half-Life 2 modification. Valve also no longer categorizes Garry's Mod 13 as a modification, but rather as a full game, due to its ubiquity and popularity. It requires at least one Source engine game in the user's account to play, and therefore is offered in a reduced-price bundle with Counter-Strike: Source or Team Fortress 2 for those who do not meet that criteria. 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.
