Leave it to Coffee Stain Studios to deliver totally serious news on April Fool's Day: The indie developer launches Goat Simulator on Steam today. For $9.99, PC players can raise hell as the adorably mischievous goat, scoring points by breaking items as they would in a game like Tony Hawk's Pro Skater, save for the epic tricks.

To whet the appetites of today's unfunny pranksters, Coffee Stain Studios did offer goofy "release day patch notes" in Goat Simulator's official Steam forums. The day-one patch "added more goats," "added more goatiness to the map," increased "goat tongue realism" by 25 percent and "probably added some bugs." The patch did not change the goat in the game to a hawk, which would have made more sense of our conversation with the developer at the Game Developer's Conference in March.
