Surgeon Simulator 2013 is a darkly humorous over-the-top operation sim game where players become Nigel Burke, a would-be surgeon taking life into his own shaky hands, performing life-saving surgical maneuvers on passive patients.

The original prototype – developed in just 48 hours at the 2013 Global Game Jam in January – challenged players to complete a heart transplant, armed only with an arsenal of clumsy and inappropriate tools and a hand that was diabolically difficult to control, using a combination of keyboard and mouse actions.
