ARGOS

ARGOS is the robotic juggernaut controlled by ODYSSEUS, the central computer of the prison.

Background
Argos is an enormous building-sized multi-legged rover, armed with missiles, precision laser weapons and an aadvanced array of sophisticated sensors used for communicating with ODYSSEUS.

In the heist pulled by Presper's men, ARGOS was damaged on its release. This damaged it slightly by loosening its movement servos and made it impossible to receive instructions. The machine will attempt to retrieve prisoners no matter what instructions it is given. This is problematic, considering that there is a massive hole in the prison and that the prisoners can walk right out again.

Behind the scenes
Argos, in Greek Mythology, is the loyal dog of Odysseus.
