Goat Simulator is one of those games that became popular because of how unique it essentially is. In it you are a goat but are able to do all sorts of things. In the Waste Of Space DLC, which is out tomorrow on March 21st for PS4, it even looks like the goat can fly a spaceship. The DLC focuses on helping to crowdfund a space station through headbutting things and people, and once that it done the goat can dabble in a bit of Space diplomacy.
Waste Of Space is the biggest map available for Goat Simulator and to be honest it is a twist on the Space genre. On PC the DLC costs £3.99 so expect a similar price on PS4.
