You are an experimental unit, given an experimental mech, you are designated as "Senior Operator." You go to the giant Mech, and the chest hatch opens up with all the control boards igniting a deep red, and the head light turns on, then a deep voice breaks the silence. "Welcome aboard, Operator. All systems Nominal, weapons armed. Climb in, and I will show you what everything is." The Mech crouches down, and holds out it's hand, waiting for you to climb on.
