Surgeon Simulator 2013 somehow managed to make the process of brutally murdering a patient hilarious, and now the experience has been translated to touch. What makes the game both challenging and funny is the delightfully difficult controls: heart surgery requires deft precision, but in the game you're only able to flail around wildly. It's essentially a messy puzzle game, where you need to figure out how to best use the tools at your disposal — which include, for some reason, a hammer — to complete the task at hand. What's the easiest way to crack open a rib cage? You could use a bone saw, or you could just smash it with the hammer. It's your choice, but you'll need to inflict as little damage as possible on poor old patient Bob.
