X6-88

X6-88 is a synth working as a Courser for the Institute in the Commonwealth in 2287. He is a possible companion to the Sole Survivor.

Background
X6-88 is an Institute Courser, designed for high-risk assault and retrieval operations above ground. X6 is very capable at engaging enemies at range and is equally capable of direct assault and more subtle approaches. He speaks in an animated, robotic style fashion.

X6-88 is first seen by the Sole Survivor inside of Kellogg's memories, giving the merc a mission to hunt down Virgil. He also takes S9-23 to the Institute in the memory.

Shortly after arriving at the Institute, Father tasks the Sole Survivor with helping to retrieve the leader of a band of raiders, Gabriel, a mind-wiped runaway synth formerly known as B5-92 from Libertalia. X6-88 is the courser dispatched to aid in this task. Completing the later quest Mankind - Redefined makes him available as a companion for the Sole Survivor. He can be found at the Synth Retention Bureau. If he is not there, he can be found north-northeast of Nordhagen Beach settlement near a beached fishing boat.

Effects of player's actions

 * When getting the max approval he will give the Sole Survivor the Shield Harmonics perk, which grants a bonus of 20 points to Energy Resistance.
 * He will like it if one enters a power armor. After which you must wait at least 2 hours before he will like it again.
 * He will like if side-missions from the Institute are accepted, despite the fact that the game doesn't notify about it (can be checked on PC by clicking on him in the console and typing before and after).
 * When completing the Nuclear Option, and X6-88 was not sent to a settlement, he can be found in the SRB section of the Institute after the security lockdown is lifted along with ~7 other coursers.
