''Garry's Mod
includes the functionality to modify the game by developing scripts written in the Lua programming language. Notable mods (known as "addons") include Spacebuild
, Wiremod
, Elevator: Source
, DarkRP
, Prop Hunt
, and Trouble in Terrorist Town
. Specialised servers, known as Fretta servers, rotate between custom game modes every fifteen minutes. Garry's Mod'' version 12 introduced the "Toybox" section, through which the player could browse and install user-created mods. This was replaced by support for the
Steam Workshop in version 13.
Fretta Contest and Trouble in Terrorist Town In late 2009, Facepunch launched the "Fretta Contest", a competition in which people were to develop ''Garry's Mod
game modes using the proprietary Fretta programming framework, with the winning game mode to be added to the base game. The winner of this contest was Trouble in Terrorist Town
(TTT
), which was added to the game in July 2010, alongside another mode, Dogfight: Arcade Assault
. TTT'' assigns players to three groups: Traitors, Detectives, and Innocents, similar to the party game
Mafia. Detectives are known to all players, whereas Traitors are only known to other Traitors and otherwise appear as Innocents. While Traitors attempt to eliminate all other players, Innocents and Detectives need to co-operate to identify and eliminate all Traitors. To do the latter, Detectives are given special equipment, such as
DNA scanners that can trace a dead player's killer.
Prop Hunt The game mode
Prop Hunt was created by Andrew "AMT" Theis and popularised through ''Garry's Mod
. In Prop Hunt
, the players on one team are disguised as props and set to hide on the game map while the other team seeks after them. Game modes based on Prop Hunt
were later included with games like Call of Duty: Modern Warfare Remastered, Call of Duty: Black Ops III, Fortnite Battle Royale, and Genshin Impact. Players recreated it in others, such as Rocket League and Fortnite Creative''.
GMod Tower In July 2009, four developers working under the name "PixelTail Games" opened a ''Garry's Mod
server called GMod Tower
. GMod Tower'' was a network of servers, designed as a social media platform for users to play
minigames with friends and socialise in a hub area. Within hours of the server's opening, the website for
GMod Tower reached two million views.
GMod Tower temporarily shut down between January and April 2012. PixelTail Games later expanded
GMod Tower into
Tower Unite, a standalone game that replaced
GMod Tower upon its
early access release in April 2016.
Machinima ''Garry's Mod
has been used as the basis for machinima. One of the more notable examples is Half-Life: Full Life Consequences, which is based on a fan fiction set in the Half-Life universe, penned in 2008 by a user named Squirrelking. YouTube user Djy1991 used Garry's Mod'' to animate the fan fiction, using
literal interpretations of some of the work's
typographical errors and awkward grammar.
Glue Library incident In June 2022, the author of the popular ''Garry's Mod'' addons "Glue Library", "View Extension", "Action Extension", and "Ambient Occlusion" altered their work to display
shock images such as
goatse and play loud sounds. The addons' new source files contained curses directed at Newman, Valve co-founder
Gabe Newell, and Steam moderators. According to
PC Gamer, the files appeared to indicate the changes were a "deliberate prank" and not due to the addons being compromised. Another user changed their "
Trollface Playermodel" addons to present the user with a different set of explicit images and slurs loudly played back in the voice of the cartoon character
SpongeBob SquarePants.
Prohibited content Facepunch Studios
blacklists servers that are malicious, depict
sexual violence, or contain content that is
not safe for work but not marked as such. In April 2023, following a
Twitter poll with close to 50,000 respondents, the company additionally banned the glorification of
Nazism, including the display of
swastikas and the
Nazi salute.
Copyright claims In response to a
takedown notice from
Nintendo in April 2024, Facepunch Studios began removing Nintendo-related Steam Workshop entries. Due to a large backlog, the studio asked community members to delete their relevant uploads to aid this process. Newman denied rumours that the notice was issued by a party unrelated to Nintendo, as had been the case in past instances. Newman received a takedown notice relating to the
Skibidi Toilet web series in July 2024. The series's creator,
DaFuq!?Boom!, argued that he wanted to subdue the spread of pornographic derivatives of his work. == Development and release ==
