SPX Series

Lexicon Entry
13 years ago, The Dayless Night Incident resulted in horrific crimes across the country. Seeking to counter this, the Secret Police developed these robots in order to track down criminals.

In addition to terrain and obstacle-detecting laser sensors, each model boasts a specialized tracking function that engages "Pursuit Mode" upon detecting a target.

Until their target is no longer detected for a certain amount of time, they will continue their pursuit, neutralizing any obstacles in their way.

As a failsafe during their initial development, a sound byte was installed in the machines that, if parsed, would deactivate them. Inspired by this riddle-solving, the personnel dubbed their beloved creations "sphinxes"--or "SPX" for short.

Maestro Detective, head of the Secret Police, became increasingly reckless in his pursuit to make the SPXs a more powerful deterrent. This ultimately resulted in tragedy, as droves of children wound up dying in his research facility.
