Goat Simulator is already one of the wackier games out there, but if you want to dial up the weirdness even more, a new expansion out today on Xbox should do the trick.
Goat Simulator: Payday is a $5 add-on for Xbox One and Xbox 360. It's a crossover of sorts with Overkill's Payday heist game, and lets you commit crimes as an ibex, a camel, a dolphin in a wheelchair, or a flamingo. You can switch between any of them on the fly, and you might want to do that, since each creature has unique abilities. The action takes place on a brand-new map.
You have a bunch of missions to complete, which you can track using "Pranknet." One of the challenges involves breaking into a version of developer Coffee Stain Studios' office in the game and uploading an unfinished game to the internet. Another mission is called "Exploding Cake." Its description speaks for itself: "We've had reports of people having fun. You need to go ruin their party. Find the party, find the cake, and blow it up."
The game also lets you wear masks like you can in Payday. Watch the Let's Play video above to get a closer look at the expansion.
Goat Simulator: Payday can also be acquired through a bundle that comes with the base game and the expansion. It's discounted to $13.50 right now. Goat Simulator by itself goes for $10.
The expansion is also available on PC, but it doesn't appear to be out on PlayStation 4.
