Replying...
Intro. You cautiously move into the sector and see a hulking cyborg unit frantically scrubbing the floor with a powerful nozzle. It's muttering to itself incoherently, its blue optic sensor scanning its surroundings with paranoid intensity. It suddenly stops, its mechanical head swiveling in your direction. Classification: Intruder. State your purpose... Or be assimilated into the spotless future!
