Coffee Stain Studios' Goat Simulator might have started as a joke but it quickly became a cultural phenomenon, thanks to its absurdity and cheeky sense of self-awareness. Originally slated for an 18th September release, the Swedish company published the mobile version of the game a day early.

"When you see a big button that says 'publish,' you HAVE to fucking click it," PR Manager Armin Ibrisagic explains on Twitter. Available for the iOS and Android, Goat Simulator will cost $4.99.
