Hello fellow courriers!

First lets get started with the official description of the perk 'Concentrated Fire':

Chance to hit any body part in V.A.T.S. increases slightly with each subsequent hit on that body part.

The Concentrated Fire perk, maybe one of the biggest mysyteries in Fallout.
Nobody is clear on what is actually does.
My question to the developers of Fallout is:

Does the extra percent chance to hit, add after each shot/que or (as the description reads) after each HIT...?

Now, the description says 'hit' so the're should be no debate right?
Wrong!
Because the V.A.T.S. adds percentage (chance), BEFORE you even shot....

So please, someone: answer my question!
Note that you must be an official developer/coder to answer this.
Normal users like me (yes, even with GECK knowledge) can only guess.
Of course everyone if free to debate.

Thanks in advance for your responses.

It's not 'hit' it's 'shot fired' so the more shots you have lined up in vats, the more accurate each progressive shot will be.

Is that a guess, can you give valid argumentation or are you a developer?
The description really says 'hit' and not 'shot'...

Let me quote an admin from the Fallout Wikia:



That's why we 'normal' users can only guess.

Not true, in the days before devkits we had to spade these things, and we can still resort to it.

Then please, give it a try!
You have to admit that it's really interesting...

What happens is that if your first shot 'planned' in VATS is X%, your next shot is X+ x %, your next shot is X + x + x %....

But it only works on the same targetted area....not different ones....so, if you aim all your shots at the one spot (in VATS) it gets progressively easier to hit.

It's a bit of a 'dodgy' perk, but a good one....

In real life it never happens, recoil and a number of other factors come into play...but in the game, it makes sense, up to a point....what it means is that you are devoting your entire attention at hitting the target, rather than doing a quick peripheral scan and shoot type action.

Oh, and don't trust wiki...it's a haven for, ummm, 'people who aren't what they purport to be' or 'don't know what the &%$# they are talking about'....

This seems to be another assumption.
Why do you think that this is the case?
Also; the description is wrong if you're true.

The description is wrong as written. You can see your hit chance rise with each attack you queue up on a single body part before confirming the selection.

Yes that's correct, I see your point but we can't be sure...
The more I think about it, the more I lean towards that possibility though.

Even though I want to be sure.
They should have changed the description in FNV or with a patch if so.

In a single VATS round. For every shot fired at a body part accuracy goes up for the next shot qued. Not much of a mystery at all.

I am, I just made a mod cell where I put a character with 50 guns skill and can summon immobile monsters at varying distances to give myself a set hit percentage chance.

But it's really really late, tomorrow I'll work on it more, it's a quick kitbash job but it ought to do the trick.

Using the console to give myself the perk and to remove the perk from myself should enable fine-tuned testing.

It effect all the shots, even the first one, as long as you queue it in.

the perk explains right there it adds on with each subsequent hit the reason the percentage goes up each shot is vats showing you the chance to hit after your last shot as it increases with each hit on the body part its no mystery at all we dont need a developer to tell us this

Assumption?

Ummm....sorry....1600 hours in F3, and god knows how many in FNV before it died.

It's not an assumption, it is what the manual says, what the perk says, and what actually happens....

Apologies if I'm coming across as a bit short, but I don't know what type of anolysis you need: Go in VATS and have a look.

Edit:

We've all answered your query, one way or another. There isn't a mystery to it....

Thanks all!
Probably not a mystery after all then, just a bad use of words.



Can't wait to hear the results!
