“Normally, I wouldn't give a mole rat's ass about offing some Commonwealth low-life, but too much of that will attract unwanted attention. It'll be easier to do our jobs if we don't have every bounty hunter from here to the Capital Wasteland after us. A little more discretion is all you need.”
X6-88 is a Gen 3 synth and member of the Coursers in service to the Institute in the Commonwealth in Fallout 4. He is a possible companion of the Sole Survivor.
Quick Answers
What is the role of X6-88 in the Institute?
X6-88 serves the Institute in 2287 as a courser-class synth, executing high-risk assault and retrieval missions in the Commonwealth. He is adept at both ranged combat and direct assault, as well as subtler strategies. If the Sole Survivor aligns with the Institute, X6-88 may become a potential companion.

Can X6-88 still be a companion after the Institute is destroyed in Fallout 4?
X6-88, the synth courser from Fallout 4, can remain a companion post-Institute destruction. However, he may exhibit hostility if the player is responsible for the destruction. His dialogue remains unchanged, continuing to refer to the Institute as allies. His presence can incite hostility from Railroad members. If dismissed, he returns to the Institute SRB, behaving as if it remains intact.

What is X6-88's affinity and how does it affect gameplay?
X6-88, a courser-class synth, can become a companion in Fallout 4 if the player aligns with the Institute. His affinity is influenced by the player's combat prowess. Achieving maximum affinity with X6-88 unlocks the Shield Harmonics perk, enhancing the player's Energy Resistance by 20.

Why doesn't the Railroad turn hostile when you bring X6-88?
Despite X6-88's alignment with the Institute, he assists the Sole Survivor against Institute forces, preventing the Railroad from turning hostile. However, if X6-88 is brought to the Railroad HQ, hostility is triggered. Quick exit and re-entry without engaging the Railroad members can reset their status to friendly, with X6-88 remaining outside.

Where can X6-88 be found in Fallout 4?
In Fallout 4, X6-88, a courser-class synth, serves the Institute by executing missions in the Commonwealth. He becomes a potential companion if the player aligns with the Institute. Post the Nuclear Option, X6-88 is located at Nahant Wharf, provided he survives.

Background[]
At some point prior to 2287, from the Institute's population of Gen 3 synths, X6-88 was picked out and designated a Courser, the elite class of synth designed for high-risk assault and retrieval operations above ground in the Commonwealth.
While diving into Kellogg's memories in the Memory Den, the Sole Survivor witnesses a memory of the Courser visiting Kellogg at Kellogg’s house in Diamond City, we see X6-88 ordering Kellogg to hunt down the rogue Institute scientist Virgil. Afterward, X6-88 took the child synth, S9-23 back to the Institute.
A short time before the Sole Survivor infiltrated the Institute, X6-88 was dispatched to Libertalia to retrieve the runaway synth B5-92, now known as Gabriel, the leader of the raider gang occupying Libertalia after being mind-wiped by the Railroad.

Effects of player's actions[]
- X6-88 becomes available as a companion after completing Mankind - Redefined by attending the Directorate meeting in the Institute and starting Mass Fusion.
- Reaching maximum affinity with X6-88 grants the Shield Harmonics perk, which offers a permanent +20 increase to Energy Resistance.
- He likes the act of entering power armor. After this, the player character must wait at least two hours before he will like it again.
- He also likes accepting side quests from the Institute. Note: there won't be a HUD notification about this particular trigger (can be checked on PC by clicking on him in the console and typing getav CA_Affinity before and after).
- When completing The Nuclear Option, and if X6-88 was not sent to a settlement beforehand, he can be found in the SRB after the security lockdown is lifted along with approximately seven other coursers, and will be hostile.
- If he was not killed during The Nuclear Option in the Synth Retention Bureau, he can possibly be found close to the Nahant Wharf.
- X6-88 cannot be romanced.

Notes[]
- X6-88 is the only companion who can follow the Sole Survivor when fast traveling in and out of the Institute.
- He is the only companion who dislikes the Sole Survivor not wearing any clothes.
- X6-88 will become hostile if the Sole Survivor attacks synths found in the Commonwealth.
- Upon first meeting X6 at the Nahant Wharf, if the Sole Survivor does not complete the mission or go to the location, he will follow as a second companion anywhere the Sole Survivor goes. However, he will pick fights with the Brotherhood of Steel and various other allies that spawn there.
- He can be found at the Synth Retention Bureau area within the Institute. Depending on where one started the Synth Retention quest, he might also be in a shed at Nahant Wharf (often he will fight the BoS patrol dropped off in a scripted vertibird landing close by) or in front of a fishing boat about 100 yards due northeast of the Nordhagen Beach settlement, the north and south entrance to Libertalia respectively.
- If X6-88 is brought to Boston Airport after the Prydwen arrives, the automated spotlight turret near the fast-travel point will track him and sound an alert even if the Brotherhood is not otherwise hostile towards him.
- If X6-88 is dismissed while on the Prydwen, it will cause X6 to fight with the Brotherhood. X6 will not travel to the desired location until combat has ceased.
- Unlike the Railroad, the Brotherhood won't turn hostile if he is brought to the Prydwen (unless dismissed near there).
- Despite the hostility between the Brotherhood and the Institute - when meeting Danse, or vice versa, the two will not be hostile. Even when one of them is not recruited, and they will have a short conversation with X6 even stating he is with the Institute if the player character has X6 and tries to recruit Danse.
- Compared to other companions, he is very neutral about how the Sole Survivor resolves side quests. He will often comment at the end of quests and even expresses his opinions, but this does not usually change his relationship values.
- If the Sole Survivor is declared an enemy of the Institute, X6-88 will become unrecruitable and will be hostile until he is killed. This can prove to be a problem if he was sent to a settlement, as he may engage the settlers.
- If the Sole Survivor brings X6-88 to the Railroad HQ, the Railroad will automatically turn hostile. The Railroad will also turn hostile if one brings X6-88 near the Old North Church or the fast-travel marker for the Railroad HQ in north Boston.
- If completing The Nuclear Option by siding with the Railroad and without having been banished from the Institute, X6-88 will continue to be available as a companion. Unlike some of the other companions, he does not have any new dialogue reacting to the destruction of the Institute and will speak as if they were still allies. Bringing him to the Railroad will still cause its members to turn hostile. In this case, if one exits quickly via the door to the Old North Church without attacking any of the Railroad members, then re-enters the area, X6-88 will remain outside the door and Railroad members will revert to friendly status (even if some of the unnamed Railroad agents have been killed by X6-88).
- He will often give hints during dialogue options which can point to how he wants the Sole Survivor to answer. He will like or sometimes even love if responding accordingly. One example of this is during Building a Better Crop where, if one answers Cedric Hopton with a threatening response as X6 implies they should, he will like it.
- When dismissing X6 to travel with Nick Valentine, he will have a short dialogue urging Nick to watch out for "the future of the Institute," despite Nick being a "rogue" synth (as far as in not working for the Institute). Nick will respond sarcastically and X6 will then travel to wherever he was sent to.
- X6-88 seems to actually take pride in his status as a Courser, sometimes stating "The people of the Commonwealth are terrified of Coursers. They should be."
- After Synth Retention, the Institute Coursers will sometimes tell "Unit X6-88 speaks highly of your combat skills." and Justin Ayo will say "X6-88 was impressed with your work at Libertalia. He does not give praise lightly. Well done."
- He will mention the Institute once had an all-robot sports event when taken to Easy City Downs.
- He has no affinity reaction to returning the deathclaw egg to its nest during The Devil's Due but will still comment, however.
- Upon being killed by the player character, he may say, "I can't... I can't...," "Functions terminated," or "Not... like this..."
- He appears to be afraid of flying, as he dislikes boarding vertibirds. If taken to Skylanes Flight 1981, he will remark that he "can't think of a worse way to die" than a plane crash.
- Unlike Nick Valentine and other synths, X6-88 has no innate damage resistance or energy resistance and is entirely reliant on armor for protection. Despite his unusually high S.P.E.C.I.A.L. stats, his health is identical to that of all the other human companions, and he lacks the enhanced health and innate damage and energy resistance shown by other coursers.
- X6 will occasionally give moderate amounts of fusion cells when talking to him, similar to MacCready giving ammo and Strong giving meats.
- If given a Stealth Boy, X6 will use it in combat.
- If taken to a settlement, settlers will sometimes say that they hope X6 isn't there for them. He will reply that he trusts that means he has their cooperation.
- If sent to a settlement, X6-88 will become hostile to any BoS vertibirds, including ones the Sole Survivor uses for transportation via a Vertibird signal grenade. This will cause all settlers at that settlement to also become hostile to the vertibird. This is in spite of the fact that he does not become hostile to BoS vertibirds called via a signal grenade if he is a companion.
- X6-88 has both the highest Endurance and Perception of any companion in the game with 17 Endurance.
- If X6-88 is sent to Boston Airport after dismissing him as a companion, he will attack the nearby Brotherhood members in an endless loop.
- If not assigned to a settlement,X6-88 has a rather unique exit after being dismissed: he will almost immediately contact the Institute to relay him back.

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.[verified]- 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 player.moveto command, the player character gets teleported to the Institute but X6 does not appear. To prevent this, simply dismiss him outside the Institute. To remedy this, pull up the console and enter prid 000e210a, then type in enable and finally moveto player [verified]
-
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.[verified] - X6-88 may be found wandering the Commonwealth even though he is assigned to a settlement. When found he will be hostile towards the player if the player destroyed the Institute. After fast traveling to the settlement he is assigned to, he will still be present there.[verified]
- 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. The fix is unknown.[verified]
- If X6-88 is the companion when boarding the vertibird for the Spoils of War quest and becoming 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.[verified]
- 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.[verified]
- If X6-88 is killed, after becoming hostile with the Institute, his body may disappear and then reappear at Nahant Wharf where one first meets him.[verified]
- 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. [verified]
- Even after destroying the Institute during The Nuclear Option with X6 as a companion, he will not become hostile and will even go into the teleporter with the player character. [verified]
- For some reason once one is able to recruit X6-88, he will be nowhere in the Institute. The Sole Survivor can find him southwest of Libertalia and northeast of Nordhagen Beach, by a shored boat.[verified]
