X6-88



X6-88 is a synth character residing within The Commonwealth in 2287, and a possible companion.

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.

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. X6-88 is the Courser dispatched to aid in this task. Completing the quest Mankind-Redefined makes him available as a companion for the Sole Survivor. He can be found at the Synth Retention Bureau.

Appearances
X6-88 appears only in Fallout 4.

Bugs

 * If X6-88 falls into the water in Libertalia, he won't be able to interact with the player character and would not leave the water. This can be fixed by shooting him several times or proceeding alone to find Gabriel or simply advancing further into Libertalia.
 * If X6-88 is downed after defeating the raiders he may not be able to show up at the Sole Survivor's quarters.
 * When commanding X6-88 to travel to a settlement while the player character is in the Institute, he may disappear. When using the console to teleport the player character to him via the command, the player character gets teleported to the Institute but X6 does not appear. To prevent this simply dismiss him outside the Institute.
 * Even after the player character has destroyed the Institute, X6-88 still can be found near the Nordhagen Beach settlement and still can be recruited as a companion. Moreover, dismissing him will simply make him teleport back to the Institute SRB as if it is not destroyed.
 * X6-88 may be found wandering the Commonwealth if assigned to a settlement. When found he will be hostile towards the player if the player destroyed the Institute. (i.e. X6-88 was stationed at Murkwater construction site, but he left the site and was later spotted fighting Brotherhood Patrols near Croup Manor.)
 * When found, X6-88 may be still essential, or not and may be killed.
 * X6-88 may continue following the player character even when dismissed or replaced with another follower. This prevents all interaction with the Railroad. Fix is unknown.
 * For some reason once one is able to recruit X6-88, he will be nowhere in the Institute. The Sole Survivor can find him between SW of Libertalia and NE of Nordhagen Beach, by a shored boat.
 * If X6-88 is the companion when boarding the Vertibird for the Spoils of War quest and become enemies with the Institute, X6-88 will fall off the Prydwen, become hostile, and become invulnerable. This will become an issue after the quest completes, as he remains by Boston Airport and will distract all troops, including Liberty Prime, and one will not be able to continue.
 * If sent to a settlement in forehand, X6-88 will not become hostile if one completes the main questline with the Railroad. This could happen because of that one never technically became "enemy" with the Institute.
 * If X6-88 is killed, after becoming hostile with the Institute, his body may disappear and then reappear at Nahant Wharf where you first met him.
 * If X6-88 is killed after the player character becomes hostile to the Institute, his body may disappear and then reappear on the beach Southwest of Libertalia, next to a shored boat.
