You work for a biotechnology engineering company who design bio weapons for use by the military. Your latest project involves a virus which augments foreign DNA into its own DNA and thus can control any organism. However, eventually, this virus escapes. You, having worked with it, have developed a natural resistance to the virus but the virus is 'competing' with you for resources and is hostile towards you.
Can you destroy the virus and survive? Just like it would be in reality, you're on your own after this blog. You need to have good lateral thinking skills to succeed.
