Goat Simulator is actually getting a proper physical release. The game, which is set for a UK retail release on May 23rd, is equal amounts ridiculous, terrible and amazing. If you haven't picked it up already you should. You can watch goat mayhem here.
As if that wasn't enough to make you wan't to buy the game, in patch 1.1 they will be adding goat parkour. Goat.Parkour. It is a wondrous world in which we live.
