You've got to appreciate Surgeon Simulator 2013 , even if it's not something you want to necessarily play. One could argue that, more than anything, it plays you. A fun bit of extra content has found its way to the goofy, chaotic, and at times disgusting sim today on Steam.
By way of a free update, Surgeon Sim players can now cut up Team Fortress 2's Heavy as -- who else? -- the Medic. Not all of Valve's collaborations make total sense (I still love most of them, regardless) but this one does.
