There are a few places in Fallout 3 where having a higher Perception will trigger the ability to notice certain things upon entering a room or building. Occasionally this can lead to useful discoveries.

Does anyone have any examples of these kind of situations? So far, I only know of the one regarding the Anchorage War Memorial loot—Preceding unsigned comment added by PwnzerfaustMonk (talkcontribs). Please sign your posts with ~~~~!

I think your perception influences what you notice about the Wests' corpses in Blood Ties. With high perception you get something like "it looks like somebody's been gnawing on the bones", with low PE just "they're dead". Not exact quotes of couse, just to illustrate the point. -- Porter21 (talk) 09:46, 20 February 2009 (UTC)
I think medicine is what determines if you see the bite marks on those corpses or not. I thought perception was only good for getting things to show on your radar. Dcruze 09:53, 20 February 2009 (UTC)
You are right, Medicine is the determining factor (0-29 gives no clues, 30-49 gives 1 clue, 50-69 gives 2 clues, 71-89 gives 3 clues, 90+ gives all 4 clues). No idea then, usually don't play chars with high Perception. -- Porter21 (talk) 10:05, 20 February 2009 (UTC)
Along with Charisma and (debatably) Intelligence, Perception is one of the pointless SPECIALs. The only good it does is increase the linked skills' values. The radar detection thing is pretty useless really, and even if you do find it useful, you can just get dogmeat as a follower (who has a high perception) and he will detect- this renders your perception useless. Still it accesses some good perks such as Sniper and Better Criticals. 01:14, 21 February 2009 (UTC)
I highly disagree! I find the detection very useful as I prefer to stealthly snipe my enemies from a distance so I can get the sneak bonus and so I can get multiple shots off before they get shoot at me/hit me if the first shot doesn't kill them. I don't use Dogmeat because he always seems to die on me within the 3 fights I get into, and because I don't want him to ruin my stealth. And don't mention "Puppies!". Even though I have Broken Steel, it's not availible untill level 24 (I think). These conditions factor into me needing that detection range and I love it.
PS: Don't push your opinion into others as if it were fact. I find it highly rude, arrogent, and insensitive. Sometimes I just don't understand other people… --TheREALBloodscar 10:12, 26 May 2009 (UTC)


Not sure I like how the linked headers look. You never see anything like that on Wikipedia, and this Wikia is supposed to follow their manual of style. Dcruze 09:53, 20 February 2009 (UTC)

Well, they're not really necessary now that we have the game icons. Ausir 10:12, 20 February 2009 (UTC)

View Distance

"Be aware that a high Perception with a low view distance may be disadvantageous, as you will "sense" your enemies but not know where they are."

What's means "low view distance"? Isnt the range of view the same for all Players? --VikingII 12:22, 16 April 2009 (UTC)

They mean like indoors with walls in the way, low light areas, etc. Where something is hindering your view as a player, not as a character.

In a contrast to that, what about how far your perception detects (1=x meters, 10=y meters)? 14:58, September 22, 2009 (UTC)

Compass is ass backwards.

Just went looking for Dogmeat. Set a marker at where Scrapyard would be. Ended up at some Enclave training place with an Enclave Research Computer sitting outside. As it turns out, my compass led me too far, and it seemed to show me that Scrapyard was in the dead center of the outdoor research area. Upon facing the correct direction to Scrapyard (North/northeast), my compass's Marker (which was set in the North/northeast) was completely ass backwards, and pointing me South/Southwest.

You mean back-asswards? Lol --TheREALBloodscar 10:01, 1 June 2009 (UTC)

Can You use Mentats to......

temporarily boost your perception to get a perk? is it possible? or does the perk only go from the base special, and not the current?

   You cannot; perks only take into account your non-boosted stats(excluding bobbleheads and items that mimic bobbleheads such
   as the lucky eight ball). Keemonto 13:40, September 21, 2009 (UTC)

New Vegas Bug?

I don't where to put this, but here goes.

I have noticed a few times that when I've been in a cave or anywhere else underground I can't 'sense' enemies on my radar any more. I have ED-E and 7 Perception. Works fine outside. Can't remember when I first noticed and I don't think it's every time. Just wondering if anyone has noticed this? --Webley 06:29, October 28, 2010 (UTC)

EDIT: On further investigation, it seems it is just reduced not gone completely. Still, curious if this is a bug or a feature.

I have noticed this to. I think it's a feature. Outside, you can hear and see, while inside you can't see through walls and the cramped space makes hearing difficult. 02:58, November 6, 2010 (UTC)

This happens to me outdoors as well as indoors, on the PC. 8 Perception and ED-E as a companion. 21:12, February 2, 2011 (UTC)

New Vegas Accuracy

The in game description and the Fallout: New Vegas primary statistics page both state that perception has an effect on accuracy. The only mention of New Vegas in this article is to point out that it doesn't. Neither page sites a source or research or any specifics. Can anyone shed a little light here? 05:06, October 29, 2010 (UTC)

Ive heard a buzz on a bunch of Game Forums that Perception does nothing for accuracy. Someone even mentioned comparing a lvl 1 perception/100 gun vs a lvl 10 perception/100 gun and noticed no difference. Though this is just me taking their word for it. Im guessing perception does something to VATS accuracy? I noticed in my playthrough that even though I had maxed gun, my VATS couldn't hit anything within 20 metres of me. 22:24, October 30, 2010 (UTC)

I would trust that comparison more if they had, say 50 gun skill. In Bethesda's skill system extreme high and low numbers tend to break the rules. 09:21, November 12, 2010 (UTC)

  • I had a perception of two and then on my second character, 1, and have no accuracy problems at all. In the older games it was useful but...now it is pretty useless. Even with that low of a perception I still see hostiles on my compass before they are close enough to notice me. --Pongsifu 04:29, November 23, 2010 (UTC)

Seeing Longer Distances?

Ok so the page says Perception lets you see objects at farther distances but after a quick test I have found no difference in noticing people from farther ranges. Tested with 7 Perception person showed up the same point as with 10 Perception. The extra Perception was added with hat and glasses. --1stRecon 04:25, November 23, 2010 (UTC)

It means the red "hostile" markers on your compass will show up for hostiles further away --Pongsifu 04:29, November 23, 2010 (UTC)

I find perception invaluable

I always max perception, (easy with with 4 eyes, implate, and a hat, maybe an intensive training). It's extremely useful for sniper builds. If you can't spot an enemy from afar, then your long range weapon is useless. With 10 perception, you can have enemy on your radar that won't even get drawn unless you zoom in with scope.

I don't like keeping companions around as they screwed up your combat plans and make the game too easy, so no help from ED-E, 10 perception all the way. (7+1 str, 6+4 perception, 6+1 endurance, 4 int, 1 cha, 7+1 agility, 9+1 luck)Dvd777 07:30, November 23, 2010 (UTC)

What platform are you playing on? With graphics maxed on PC I can see enemies drawn in the distance without zooming in so far away that if I zoom in I can only hit them when standing still with a sniper rifle because it is just too hard to hit them at that distance if they're moving. What I'm saying is, they should be drawn in. --Pongsifu 07:49, November 23, 2010 (UTC)

Perception is Usless in FNV?

Ok hear me out so aside from the obvious early game stat boost that can be made up later on and like 3 speech options that require perception the only thing this dose is dictate when the red markers appear right? But the ED-E's perk boosts the red markers already so it basically balances it out right? I mean you don't have to even bring ED-E along you can just have him wait and its like having a container where ever you want. So unless your absolutely set on having Rex as a companion there's really no need for this skill at all. Or dose it do something else? --1stRecon 01:36, December 1, 2010 (UTC)

I find it useless with or without ED-E. --Pongsifu 04:00, December 26, 2010 (UTC)

Increased VATS distance?

Does Perception increase the distance that can be used for VATS? --The Bart 12:10, December 6, 2010 (UTC)

10 Perception, 1 Perception

I added the two quotes Doc Mitchell gives you for having 10 or 1 Perception in the notes section. --CptMuddles 16:35, January 3, 2011 (UTC)

New Vegas Perception Is Useless

Honestly is this stat completely useless? Ed-E's perk doesn't help. I just tested and it doesn't affect VATS accuracy nor does increase the range which you can use VATS.


dont know how it happened but my perception has been lowered drastically. I am 100% healthy, no injuries and no addictions. Any way to fix this bug?

Editing NV PE entry

I edited the PE NV entry regarding the attribute affecting VATS. There isn't a single reference in GECK regarding the use of the attribute for calculating weapon damage, spread, critical chance or wahtsoever.

According to the Bethsoft GECK page:

The gun spread formula: Spread = PerkModifiers(IronSightsBonus * CrouchBonus * (ConditionPenalty + SkillBonus) * (WalkPenalty + RunPenalty) + ArmPenalty)

The weapon damage formula: Gun Damage = (PerkModifiers(BaseWeaponDamage * DamageMultiplier * GunConditionPenalty * SkillBonus) + CriticalDamageBonus) - DamageAbsorbedByArmor

The VATS formula, Critical Chance/Hit, all guns spread conditions and all weapon damage conditions also don't use a single entry depending of PE. How come Perception influence in VATS? Also, none of the condition penalty, gun condition penalty and walk/run penalty list PE as an effect.

What PE affects is enemy detection and this will affect combat mode. That's it. So I ask again, where in hell PE affect VATS? Brfritos 21:27, July 4, 2011 (UTC)
