**Critical Hits** are hits which cause extra damage, or other side effects.

If a hit is successful, it may become a critical hit if it passes Critical Chance. The effect of the hit is determined by the another roll, on the critical hit table. Effect depends on the area hit, and various unknown variables. The effect of a critical hit can be modified by the Perk Better Criticals.

Note that the **chance** for a critical hit is determined by Critical Chance, and is **not** the same as critical effect. See Aimed Shot in the Combat section for more info.

### Example 编辑

The following example is a bit tricky: you might want to open another window with reference material
Situation: Alvin York (S5, P9, E5, C3, I5, A10, L10) is carrying a Hunting Rifle and has a Small Guns skill of 150%, and one of his traits is Finesse. He spies an armored gentleman^{Mr Metal Man}, wearing Metal Armor some distance (8 hexes) away, and decides to make an aimed shot for the eyes. This is what happens:

Alvin's base to hit is (150 - 30) + (8 * 9) + (No penalty) - (15 + 5) + 4 - 60 = 112%, a definite hit!
Alvin's critical chance is (1 * 10) + (10) + (a mysterious number^{mysterious}) = Critical hit!
Alvin rolls 1d100 for the critical effect table, and gets 85.
His damage is (0.7 * 20 * 3)^{damage} - (armor ignored) = 42

Mr. Metal Man loses 42 of his 70 hp, and staggers around blindly. With his remaining 4 of 10 action points, Alvin advances closer to Mr. Metal Man, who lost his responding turn as a result of the critical.

Alvin fires at the eyes again. BTH is the same, and CC is successful. CE rolls a 95.

Mr Man screams in agony, as a round of ammunition pierces his visor, blinding him. He falls slowly to his knees, bewildered and overcome. Bleeding from his helmet, he keels over, killed by the 56 damage AND the "instant kill" effect. With his remaining 4 action points, Alvin York marries Gracie Williams, has seven children, and dies at the age of 76.

### Notes 编辑

The only way to roll a 101 or more is to take the Better Criticals perk.

**^** ^{Mr Metal Man}
Mr. Metal Man is completely average: every attribute is 5. He has 70 HP.

**^** ^{mysterious}
This number isn't documented anywhere. But it must be enormous for this character, because whenever this character successfully hits the eyes, he also gets a critical hit. Quite possibly, it is the penalty to hit a specified body part, inverted. This would give +60 in the above example for firing at the eyes.

**^** ^{damage}
A hunting rifle's damage is 8-20. We don't know if damage is random or a function of skill: I am assuming the latter. Don't forget the -30% damage because of Finesse!

*Fallout 3*编辑

In *Fallout 3*, the critical hit feature is simplified from *Fallout* and *Fallout 2*. When a weapon is fired, it has a predefined, specific percentage chance of getting a critical hit (with a few exceptions, see below), which is essentially just added damage to the original base damage (the damage that will be dealt if the PC does *not* score a critical hit). This obviously sounds much simpler than the system of the first two games, but it is still more complex than it sounds.

### Modifiers of Critical Chance编辑

The PC's initial critical chance is determined by the Luck S.P.E.C.I.A.L. statistic. Each point of Luck adds one percent of critical chance. For example, if you have 7 points of Luck you have a 7% chance to deal a critical strike with a weapon of a x1 critical multiplier (explained in the below paragraph). In addition to the Luck stats, there are various perks that add to the PC's critical chance (see the main article for details). With the maxing out of all perks, it is possible to achieve a base critical chance of 18% with ranged weapons, or 33% with unarmed and melee weapons (due to the Ninja perk). Also, a critical chance of +15% is added to all strikes in V.A.T.S.

Each weapon in the game has a critical multiplier that is combined with the PC's critical chance. For example, the Scoped .44 Magnum has a multiplier of x2, so if the PC has a critical chance of 7% and is using a Magnum, he/she has a 14% chance to score a non-V.A.T.S. critical hit (29% with V.A.T.S). A majority of the weapons have a x1 critical multiplier (such as the Hunting Rifle). There are a few weapons that have a x0 multiplier (like the Sawed-Off Shotgun), and that makes it impossible to score a critical hit; Sneak Attack Criticals do not add any damage due to the 0 critical damage. Very rarely, you can get a non-sneak attack critical hit on a x0 multiplier weapon (tested on The Kneecapper), but because the critical damage is set at 0, it makes it useless. Because automatic weapons have so many bullets, the actual critical multiplier is much lower than the critical multiplier associated with the weapons. For example, the Chinese Assault Rifle has a rate of fire of 8 bullets a second. The multiplier is displayed as x1, but if each bullet was actually x1, there would be way too many critical strikes. The actual multiplier for each bullet is x0.125. So in practical use, the multiplier acts as x1. The critical multiplier for each weapon is between x0 and x5 (save for one exception). There are only a few weapons with a x5 critical multiplier: Sniper Rifle (and unique variant), Gauss Rifle, and--*Point Lookout* only--Lever-Action Rifle (plus unique variant). See the Critical Chance article for a full list of weapons with good critical multipliers. It should be noted, also, that the Alien Blaster (and the Firelance Alien Blaster) has a multiplier of *x100*! That means *every* shot will be a critical!

### Critical Damage编辑

Every weapon has a predefined critical damage, which is the damage added during a critical. The only modifier to critical damage is the Better Criticals perk, which gives criticals a 50% damage bonus. This is a lot more impressive than it sounds. For example, the Wazer Wifle has a critical damage of 28, but with the perk, the critical damage becomes 42, making 70 damage on a non-sneak critical and 140 damage on a Sneak Attack Critical.

### Sneak Attack Critical编辑

A Sneak Attack Critical occurs when sucessfully attacking an opponent while being [HIDDEN] by using one's Sneak skill. Successfully hitting the target will result in a guaranteed critical strike. This more specialized critical strike *doubles* the damage generally done with a non-sneak attack critical. For example, Lincoln's Repeater has a base damage of 50 (yours might be different with perks, weapon condition, and skill) and a critical damage of 50, so a basic critical hit would do 100 damage (unless you have the Better Criticals perk). When a sneak attack critical dealt, the damage completely doubles, so the Sneak Attack Critical gives a whopping 200 damage (300 with Better Criticals).

*Fallout: Brotherhood of Steel*编辑

In *Fallout: Brotherhood of Steel*, the system works much like Fallout 3, when a weapon is fired, it has a predefined, specific percentage chance of getting a critical hit) which is just to exceed the maximun limit of damage for a weapon. A secret weapon called The Slugger has the capacity to each critical hit, the enemy eject very far.
