You are a cutting-edge medicine with a single mission: To heal the human body from a deadly virus infection! For that you'll have to repair the black, broken body parts with the light, movable parts in the level. Then you'll have to get the viruses into the healed parts so they are removed by the body. Be careful though, as the viruses are deadly and will kill you if you let them touch you. Once you remove all the viruses, your mission is complete. Good luck.
