Yes, the game is really called that. Yes, you can defecate in someone’s soup. You can also do it on their heads. And on dogs. And everywhere. That’s the idea.
It’s a totally stupid concept but since it was just 52 pence (in fact, less than that as I had some free credit) on Steam I bought it, played it a lot, poo’d everywhere, got all the achievements, and have now classed it as completed.
