MacCready is the only companion in Fallout 4 whose maximum-affinity reward directly boosts your aim. Every other idolized companion gives you damage resistance, extra XP, or a utility bonus — MacCready gives you a flat 20% increase to V.A.T.S. headshot accuracy, permanently, the moment you finish his personal quest [1]. That makes him close to mandatory for any build built around VATS or a scoped rifle, but getting there means paying his fee, surviving his likes-and-hates list, and understanding a 499-point affinity wall that stops most players cold.
Quick Start: Recruit MacCready and Unlock Killshot
- Head to the Third Rail’s VIP backroom in Goodneighbor and wait for his confrontation with Winlock and Barnes to play out [2].
- Pay the 250-cap hiring fee, or pass the Charisma checks in dialogue to talk it down to 200 or 100 [2].
- Don’t worry about losing the caps for good — he refunds them once you finish the first half of his personal quest, Long Road Ahead [2].
- Play into his likes (stealing, lockpicking, mercenary dialogue) and avoid his hates (unprompted charity, unprovoked violence) [2].
- Expect his affinity to freeze at 499 until you trigger Long Road Ahead — that’s a quest gate, not a bug [2].
- Finish Long Road Ahead’s Gunner elimination and Med-Tek Research segments to unlock the path to full affinity [2].
- Reach 1,000 affinity (“Idolized”) to permanently unlock the Killshot perk [1].
Where to Find MacCready and What He Actually Costs
MacCready works out of the VIP room at the back of the Third Rail, Goodneighbor’s bar, selling his rifle to whoever can afford it. You can’t just walk up and hire him on sight — you first have to witness two former associates, Winlock and Barnes, corner him and threaten to run him out of town. That confrontation is what makes the recruitment dialogue available [2].
Once he’s willing to talk business, the sticker price is 250 caps. That’s not fixed: dialogue offers a couple of Charisma-gated responses that knock it down to 200, and a further check can drop it to 100 [2]. Here’s the detail almost every other guide skips — you’re not actually out any caps long-term. MacCready hands the entire fee back to you once you complete the elimination half of Long Road Ahead, so haggling him down is really just about not being caps-poor in the early game, not a permanent investment [2].
His backstory explains why he’s a mercenary in the first place and why his price is negotiable at all: he’s a former Gunner who broke ties with the faction over their disregard for collateral damage, and he’s chasing a lead on curing his son Duncan’s illness. Business at the Third Rail dried up specifically because Winlock and Barnes scared off his other clients — that’s the whole reason he’s willing to work for the Sole Survivor at a discount instead of holding out for full price from someone else [2].
What Raises — and Tanks — His Affinity
MacCready runs on the same four-tier reaction system as every Fallout 4 companion: liked (+15 affinity), loved (+35), disliked (-15), and hated (-35), each further scaled by how significant the action is [3]. His specific list skews mercenary and criminal rather than heroic:
| Raises Affinity | Lowers Affinity |
|---|---|
| Passing Charisma checks to demand more caps, stealing, picking locks (including owned ones), sarcastic or threatening dialogue, taking disreputable quests | Moral-high-ground dialogue, accepting menial charity work, joining the Brotherhood of Steel or Children of Atom, unprovoked violence, getting caught stealing |
The pattern is consistent: MacCready respects self-interest and competence, not altruism. Playing a purely heroic Minuteman-style character will actively work against his affinity, which is the opposite of how companions like Preston Garvey or Piper are built — worth knowing before you commit to running him alongside a save built around one of those two.
Version note: the like/hate list and 20% Killshot value here reflect the current live build; the perk’s original launch-week value was bugged to 2000% due to a typo and was corrected in patch 1.3 [1]. If a future patch touches companion affinity math again, verify in-game before relying on exact point values.
The Fastest Way to Hit Max Affinity
Affinity climbs passively just from having MacCready in your party: every ten in-game minutes he’s following you (and you’ve earned at least 1 XP in that window), you gain 40 minus 0.033 times your current affinity value [3]. Run the math from zero and it takes roughly 2.67 hours of adventuring to hit 500 affinity, and about 8.67 hours to hit the full 1,000 — assuming you never trigger a single like or dislike along the way [3]. In practice you’ll clear that faster just by doing quests he approves of, but the passive number is the honest floor.
How much you should bother accelerating that depends entirely on how you play:
| Player Type | Best Approach |
|---|---|
| New player | Ignore the math. Recruit him, play normally, and let the passive tick plus natural stealing/lockpicking opportunities carry you to max affinity over a few play sessions. |
| Casual player | Pass the Charisma checks to cut the fee, then prioritize Long Road Ahead the moment it’s offered — delaying it is the single most common reason players get stuck at exactly 499 affinity. |
| Hardcore optimizer | Farm it directly: find a safe with an attached terminal, pick the lock, then use the terminal to re-lock it and repeat. MacCready likes picking owned locks specifically, and this loop is repeatable [3]. The stealing trick (stash an item in an NPC-owned container, then retrieve it) also works but carries a hard 48-in-game-hour cooldown between repeats, so it’s a background task, not a grind session [3]. |
| Completionist | Push past 500 to trigger his flirt and romance dialogue for the Lover’s Embrace XP perk, and stick around for the wooden soldier keepsake he hands over at Idolized affinity — a memento of his late wife, Lucy [2]. |
One efficiency note worth flagging: unlike the stealing trick’s 48-hour cooldown, the lockpick-and-relock loop has no stated wait timer in the same source, which is why it’s the go-to for players actively trying to rush him to Idolized rather than let the passive tick do the work [3]. That 48-hour figure for the stealing trick is worth stressing because it’s easy to find worse advice: several forum summaries describe companion affinity actions as capped by a short real-time cooldown of a few minutes, which isn’t what the game’s own documented repeatable-action system says. Trust the in-game-hours figure over a quick “just wait a bit” tip if your farming session isn’t producing results.
The Killshot Perk: What 20% VATS Accuracy Is Actually Worth
Killshot is a single-rank perk — there’s no upgrade path, you either have the 20% bonus or you don’t [1]. What that 20% actually buys you depends on your build, because V.A.T.S. accuracy in Fallout 4 is widely documented (community testing since launch, not an official Bethesda figure) as capped at 95% no matter how much Perception, Rifleman, or other accuracy stacking you pile on. Killshot doesn’t raise that ceiling; it just gets you to it faster.
| Build | Typical VATS Headshot Chance | With Killshot (+20 points) |
|---|---|---|
| Low Perception, no rifle perks | ~35% | ~55% |
| Mid Perception, Rifleman rank 2 | ~55% | ~75% |
| High Perception, Rifleman maxed, Concentrated Fire | ~75%+ | 95% (hard cap) |
Those figures are illustrative midpoints, not exact engine output — your real number depends on your specific Perception score, weapon accuracy stat, target range, and whatever other accuracy perks you’ve stacked. What’s constant is the mechanism: Killshot adds a flat 20 percentage points to any VATS headshot attempt, and the closer your build already sits to the 95% ceiling, the more of that bonus is doing real work pushing you over the line into a near-guaranteed hit rather than padding a number you’d have hit anyway.
That’s also why Killshot is worth chasing even on a build that isn’t a dedicated sniper. A low-Perception melee or shotgun character benefits from the jump out of the 30-50% range just as much as a min-maxed rifleman benefits from the last few points to the cap — it’s one of the few companion perks that scales its value down to whatever your build is missing, rather than only rewarding a build that was already strong in that area.
FAQ
Is MacCready worth the 250 caps if I can’t pass the Charisma checks?
Yes — the fee is refunded once you finish the first half of Long Road Ahead, so the 250-cap version costs you nothing long-term beyond a temporary caps shortage. The Charisma checks only matter if you need those caps for something else in the meantime, like buying ammo or armor before you’re ready to take on the Gunners in his personal quest.
Why did MacCready’s affinity stop increasing at 499?
That’s not a bug — his affinity is hard-capped just below the 500 “admiration” threshold until you trigger and complete the Gunner-elimination portion of Long Road Ahead. Approval messages will keep appearing, but the number won’t move. If you’ve been ignoring his personal quest in favor of other content, that’s the fix.
Should I romance MacCready even if I don’t care about the story content?
If you’re already planning to run him at max affinity for Killshot, romancing him costs you nothing extra beyond the same time investment — you get the Lover’s Embrace XP perk for resting near him on top of Killshot. Skip it only if you’re planning to romance a different companion instead, since Fallout 4 doesn’t stop you from romancing more than one, but simultaneous flirting with other NPCs will tank his affinity once he’s your love interest.
Do I lose Killshot if MacCready’s affinity drops after I earn it?
No. Companion perks in Fallout 4 are permanent once unlocked, even if that companion’s affinity later falls — including all the way down to -1,000, where they’d leave permanently and refuse to be recruited again [3]. Once you’ve finished Long Road Ahead and hit Idolized affinity, Killshot is yours for the rest of the playthrough regardless of how you treat MacCready afterward, so there’s no need to keep tiptoeing around his likes and hates once you’ve banked the perk.
Companions who watch your back matter just as much in other post-apocalyptic survival games — our STALKER 2 beginner’s guide covers finding trustworthy allies in the Zone, where the wrong choice of neighbor can get you killed just as fast as skipping MacCready’s affinity math here.
