Tallboy Orders is a written note found in Dishonored.
This generator will power the floodlights. At the moment only one is hooked up, but as soon as it turns on, the tallboys will break from their patrols and attack the tenement buildings. Anyone inside, weeper or not, is to be killed.
It can be found in the Flooded District near the occupied tenement building at the Rudshore Gate on the power source for the nearby floodlight.
