ARGOS

 is the robotic juggernaut controlled by ODYSSEUS, the central computer of the prison. It's an enormous building-sized multi-legged rover armed with missiles, extremely accurate long-range laser weapons, and an advanced array of sophisticated sensors used for communicating with ODYSSEUS and tracking prisoners via their Lil' Pip 3000s.

In the hiest pulled by Presper's men, ARGOS was damaged on its release. This weakened it slightly by damaging its movement servos, and made it impossible for ODYSSEUS to command. ARGOS ceaselessly attempts to retrieve the prisoners no matter what ODYSSEUS tells it to do. This is bad because ODYSSEUS needs ARGOS to seal an enormous breach in the prison through which the PCs can repeatedly walk right out of. Further, Cell Block 13 is completely blasted open, so there's absolutely no barrier for the PCs if they get re-captured. At least the other cell blocks can hold the prisoners that the Prisoner/ARGOS recover.

Behind the Scenes
ARGOS could be a reference to a Greek city of the same name. It could also be a reference to a shop called (retailer) Argos.

Appearances
ARGOS appears only in Van Buren.
