Cult hit Goat Simulator will receive a free expansion later this month that will transform the release into a massively multiplayer online game, developer Coffee Stain Studios revealed today.

The new expansion promises to offer faction warfare between goats and sheep, along with numerous quests. Players can additionally choose to play one of five available classes, including Warrior, Rouge, Magician, Hunter and Microwave, with a level cap of 101. A gameplay trailer is available below.

The MMO-styled release launches on Nov. 20 as free downloadable content through Steam for those who already own the original title on Windows PC. Goat MMO Simulator will also be playable on Mac and Linux with full controller support.
