Courser



Coursers are the assassin and elite synths designated to carry out specific surface missions from The Institute.

They are designed to be elite killing machines, unlike others of the synth 'race'. They are noted by the Railroad and the Institute to be exceptional even for synths, as they possess exceptional strength, combat prowess, awareness and endurance. They are widely feared by the Railroad, as their first instinct when they see a Courser is to cease all operations and remain low.

Most coursers wear the Courser uniform and usually some pair of sunglasses. Some, but not all coursers, have a stern look on their face with a monotoned voice. All coursers encountered are male, though with different facial styles.

The Synth Retention Bureau is the main organization that the coursers work for. They are the ones who assign coursers their missions to go out to the surface via relay from their courser chip which allows them to have a form of teleportation. The SRB primarily uses Coursers to retrieve and reset escaped synths, with deadly efficiency.

According to Justin Ayo, Coursers are trained from Generation 3 Synths, though not all trainee Coursers may pass. Those who pass will be inducted as Coursers, while those who fail will have their memory about the training brainwashed and reassigned.

Locations
Greenetech Genetics - This is the location where the Sole Survivor will meet their first Courser; Z2-47. This Courser is after a runaway Synth, and is killing anyone in his path. The Survivor begins to chase him throughout the base, and fighting through the still alive Gunners the Courser left behind.
