Garry's Mod (stylized as garry's mod) is a sandbox physics game using a modified Source engine, created by Garry Newman. Garry's Mod was originally a modification, a "mod", for Valve's Half-Life 2, but was later made into a standalone game. It is available for Microsoft Windows, OS X and Linux.[1]


Although Garry's Mod is listed as a full game, it has no objectives and instead gives the player a sandbox to manipulate items free of restrictions, although most multiplayer servers offer original game modes created by players. Garry's Mod allows players to manipulate items, furniture and "props" – various objects that players can place in-game. Props can be selected from any installed Source engine game or from a community created collection. The game features two "guns", the Physics Gun and Tool Gun, for manipulating objects. The Physics Gun allows objects to be picked up, adjusted, and frozen in place. The Tool Gun is a multi-purpose tool for performing various tasks, such as combining props, attaching them via ropes, and creating controllable winches and wheels. The Tool Gun is also used to control add-ons created by the community. Garry has shown on YouTube that the player can use Kinect on ragdolls.

Another popular Garry's Mod concept is rag-doll posing. The player can instantiate a rag-doll model from a Source game and pose it using a variety of tools.[3] This is a popular tool for making fan-made videos and machinimas.

Garry's Mod takes advantage of the Source engine's modified version of the Havok Physics Engine,[4] which allows players to build contraptions that follow the laws of physics, allowing for very real structures and experiments.

User-created content[edit]

Different models, skins, scripted weapons (SWEPs) and maps can be added to the game. Multiplayer game servers will automatically attempt to send any custom content to the client when they connect.[5]

Fretta contest[edit]

In winter 2009-2010, a contest was held for Garry's Mod by the game's developers to create the best new game mode using a programming framework called "Fretta".[6] Fretta, Italian for "hurry", allows developers to quickly and easily create new game modes for Garry's Mod with commonly required functionality already implemented so the developers can focus on unique aspects of their game modes. Fretta was inspired by a similar fan-created framework "Rambo_6's Simple Gamemode Base". However, for inclusion in Garry's Mod, Newman decided to rewrite it with input and contributions from the original author and other developers.[7] The winners of the contest range from a recreation of the Mafia party game to an aerial combat game mode.[8] The contest winners have been included in Garry's Mod with their own Steam Achievements.[9]

Three of the winning games have been shipped, Trouble in Terrorist Town, Dogfight Arcade Assault, and Prop Hunt.[10]


On September 7, 2010, Newman added a feature called the "Toybox" to Garry's Mod.[11] It utilized the Amazon S3 service to download third party content, such as weapons, props, maps or models, directly to the users' machine while in game. In an interview with GMod news, Newman said that "One of GMod's biggest draws is the amount of third party content. I want to make it easier for people to utilize that. I really want to move away from having to download files from websites and drag them to folders, that's old school. So that's what I’m heading towards. Maps, models, saved games etc., all saved on the cloud and accessible with a click. Everything should be accessible from in-game. If it isn't, I've failed."[12]

The Toybox was shortly removed, and has been replaced with the Steam Workshop in versions 13 and up. As of January 1, 2015, there are over 495,000 mods on the Steam Workshop for Garry's Mod.[13]


Garry's Mod became available on Valve's content delivery service Steam since November 29, 2006.[1] In the past, playing Garry's Mod was free from 2004 to 2005 with the last free version released on November 27.[14] As of September 2014, the game had sold over 6 million copies.[15]
