London, 21 June 2013 - Bossa Studios announced today that an update for Surgeon Simulator 2013 will bring much loved TF2 characters into the operating theatre for more darkly-humorous surgery mayhem.

The update is completely free for all current owners.

Developed initially in just 48 hours at the 2013 Global Game Jam in January, the full game released in April 2013 and has quickly become one of the sleeper hits of the year, achieving a top 10 chart position on week of release and hitting the number 2 spot over its first weekend.
