Popular indie video game “Goat Simulator” is getting a new upgrade, making the already nonsensical game even more ridiculous but also much more fun. At the end of the week, an MMO expansion of the game, called "Goat MMO Simulator" will be available a la “World of Warcraft.”

GameSpot reports that Swedish game developer Coffee Stain Studios announced the release of the upgrade as way of thanking fans for making “Goat Simulator” a success for the fledgling gaming study. The studio has sold more than a million copies of the game for PC and around half a million for mobile devices.

The new MMO (massively multiplayer online) game will allow players all over the world to play “Goat Simulator” and will feature five different playable classes. One of these is a microwave with legs, which the studio had been teasing fans with on Twitter as the announcement date approached.

On Monday, the studio launched the trailer for the MMO expansion. The trailer shows what “the lazy developers” created in the new expansion, which sets the game in a medieval town rather than the cities of before.

The game will also feature dinosaurs and mermaids, a detail the studio also explained on Twitter. How those two features tie into the game, however, remains unexplained and perplexing.

According to The Verge, the game will be a multiplayer fantasy and the other playable modes will be Tank, Magician, Hunter, "Rouge," and regular goat, aside from the walking microwave.

The game will be available for free download through Steam on Thursday Nov. 20 and will be playable on Mac and Linux.
