BCU

The BCU, short for Bio Control Unit, is a small implant installed on the back of a person's head and connected directly to their spinal cord. All convicts in SCUM are equipped with a BCU-2 unit. This device tracks the subjects, allows them and presumably those watching to monitor their metabolism, and turns them into puppets shortly after death.

The original device, the BCU-1, was designed for medical purposes, keeping patients with brain damage alive by inducing a coma and simulating brain functions. The BCU-2 was designed for industrial and military purposes, and brought with it all the additional functions.
