X9-27 is an Institute Courser in the Commonwealth in 2287.


X9-27 is a courser, and like most coursers encountered above ground, he is in the process of completing orders given by the Institute. Encountered during the Operation Ticonderoga quest, he will not attack the player character immediately, due to this quest occurring after the player has been to the Institute. Because of this all synths remain non-hostile until attacked, this gives the player a chance to talk to him, if they want.

Unlike the encounter with Z2-47, X9-27 is accompanied by a group of synths and another courser, who is referred to as the "Second unit" by X9-27.
