The extended version of Bossa studios’ hilarious game Surgeon Simulator 2013 will be launching on Steam tomorrow.

The original browser-based game of the same title was posted on online-game site Kongregate earlier this year. Since then it has received considerable attention due to its ridiculousness that Bossa Studios decided to develop an extended version of the game.

Surgeon Simulator 2013 centers on Nigel Burke, “an ordinary guy with no outstanding skills.” The game feels a lot like QWOP but with surgery instead of running. You have to perform complicated surgeries using your keyboard and mouse to control hand movement. The extended version features more complex procedures like kidney transplants and brain surgery which can apparently be done firstly by smashing the skull with a hatchet.

The original browser game can be found on Kongregate. We highly recommend you check it out! You won’t regret it.
