The Bio-Signal is a device, planted on the right shoulder of a Civil Protection Unit. It will monitor every move they do. Monitoring things such as: "Talking, walking, running, hearing, and memory". Once the Bio-Signal device is inside a Unit's right shoulder, it can not come out, unless it is cut out.
Unit Down Edit
If a Civil Protection Unit is killed, the Bio-Signal will create a "Beeping" sound, collecting data, and telling the Nexus and other Units, that Unit's location of death. (It's best for other Units to go to the downed Unit's location to investigate.)
*A Unit is walking down the sidewalk*
*A Resistance member comes out of nowhere, and shoots the Civil Protection officer.
Dispatch: "Lost Bio-Signal for protection team unit QUICK-8, unit down at canal block five, all teams respond code three."
