you are a scientist and you have testing chamber with a panel. First button is to spawn a test subject and a button to terminate the test subject. You can spawn a new subject after you terminate one. There is a rope hold button which will hold the subject by their arms with a rope and and the rope will be attached to the ceiling. You can do whatever you want with the test subjects and inject random viruses into them. You are not assigned to anything you choose what you want to do.
