Garry's Mod, the sandbox game built on Valve's Source engine, has used simple mechanical button sounds for its menus and in-game panels since its early releases, and clips of those sounds have long circulated on soundboards and in gameplay videos. This alternate version is one of several near-identical variants shared by players, differing slightly in tone or timing from the standard press. Creators keep using it because it is instantly recognisable to Source game players, loads quickly, and gives edits a familiar, game-like feel without needing any dialogue or explanation.
