Not much happens as the security guard of the Nuclear Power plant... maybe a few minor issues here and there but its all good. Well, being a boring job, you easily drift to sleep. Bad idea. The Water Containment chambers have leaked thus causing the Control Rods to overheat. You know what happens when they overheat? Radiation, and that will effect anything in the power plant and possibly kill them without protective armor. It also effects all programmable bots and will mutate living things. So now you suddenly wake up to find the sirens blaring and lights flashing. I suggest getting to work.
