Goat Simulator is a third-person perspective action video game developed and published by Coffee Stain Studios. It was released for Microsoft Windows in April 2014, and ports for Linux and OS X were released in June 2014. Mobile versions for Android and iOS were released in September 2014. Versions for the Xbox 360 and Xbox One were released in April 2015, and for PlayStation 3 and PlayStation 4 in August 2015; these ports were developed by Double Eleven. A Nintendo Switch version containing the base game and all previous DLC was released in January 2019.
The game has been compared by the developer as akin to skateboarding games, but where the player controls a goat aimed at doing as much damage as possible around an open world map, without any other larger goals. The game, initially developed as a joke prototype from an internal game jam and shown in an early alpha state in YouTube videos, was met with excitement and attention, prompting the studio to build the game into a releasable state while still retaining various non-breaking bugs and glitches to maintain the game's entertainment value.
