From Bossa Studios:
In Surgeon Simulator 2013 you play the part of a surgeon Nigel Burke. The twist is that Nigel has no medical qualifications - it's just you, some surgical tools and a body. Your goal is to complete various operations as quickly as possible with minimal blood loss starting with a heart transplant. You control the surgeon's hand with the mouse or keyboard but the first thing you'll notice Surgeon Simulator 2013 is extremely difficult to control. You control each finger separately which is tricky in itself but the hardest thing is actually picking-up tools and using them to heal and cut organs.
