Description: NKCell - Natural Killer Cell - is a cell that can react against and destroy another cell without prior sensitization to it. They are part of our first line of defense against cancer cells and virus-infected cells. An NK cell attaches to a target cell, releases chemicals that breach its cell wall, and causes it to lyse (break up). You are one of a genetically modified NKCell that can destroy viruses and bacteria. In the game, you will be standing in a blood vein and slash incoming diseases/infected cells to keep the infection rate low, and help the host to survive. The game is simple. If you see an infection, slash it!
