The Goat Simulator is an awesome success story because it combines comedic creativity in a package that was easy to make. In fact, many of the "bugs" in the game where intentionally left because they added to the hilarity offered by the crazy things you can do with your goat.
Of course, because of the runaway success of the game, you had to know the developers would come out with an add-on to the "soon-to-be-franchise." This expansion takes the goat to a new low quite literally... It's called GoatZ and your beloved Goat is now a zombie who must consumer people to live! Imagine the horror and the comedic gold!
GoatZ will hit Steam tomorrow, May 7th, for Windows, Mac, and Linux. It will also come to Android and iOS as a standalone game for $4.99 (the same price as the original Goat Simulator).
