The controls work beautifully and the operations are varied. The Nunchuk controller allows quick selection of your surgical tools, while players need a steady hand and nerves of steel to use the Wii Remote in activities such as cutting out tumours, applying artificial membranes, removing glass fragments, repairing fractures, laser-zapping parasites, massaging a heart, draining fluid from a festering lesion and stitching wounds.
You must work under constant pressure during emergencies. Time limits are ruthless, and sometimes there are extra complications, such as operating on a plane experiencing turbulence or working in the dark. If you take too long and a patient flat-lines you'll need to revive them.
