The kill-bot protects.
BOFH needs to sleep and recuperate sometime.
With the kill-bot activated and roaming Floor Level 2, maybe with some thermal security cameras feeding it targeting information .... or maybe someone with the BOFH coding skills could re-skin 'The Works' as a pretty and addictive online game, like Pacman, where teenagers navigates the kill-bot around a maze, with a layout just like an open-plan office, eating fat security guards and middle-managers to protect the food supplies?
