Every year to celebrate April Fool's Day, video game developers tease their fans with some truly bizarre and hilarious announcements. So much effort is put into these funny announcements, that it's hard to distinguish which of these goofs are real or fake. Here are some of our favorite video game related April Fool's announcements:

Goat Simulator - An open world sandbox game where you play as an indestructible goat set loose on an unsuspecting small town. The game was made as a joke at a game jam for developer Coffeestain Games, but got support from the online community when footage of the game leaked online. The finished product is purposefully buggy and ill-made to enhance the hilarity.
