VATS



The Vault-Tec Assisted Targeting System, or V.A.T.S., is a queuing system for Fallout 3 and Fallout: New Vegas, inspired partly by the ability to shoot specific body parts in the turn-based combat system of Fallout and Fallout 2. V.A.T.S. is also used for a cinematic combat experience.

Fallout 3
While using V.A.T.S., the otherwise real-time combat is paused. Various actions cost action points, and the player can target specific body areas for attacks, inflicting specific injuries.

When using V.A.T.S. against a humanoid enemy, there are generally seven different areas that are targetable; the head, torso, left arm, right arm, currently held weapon, left leg, and right leg. However, there may be other points available when specifically facing off non-humanoid creatures (e.g. robot combat inhibitors, ant antennae).

When targeting a part, the screen displays a percentage of how likely the attack will hit the targeted area based on distance from the target, visibility of the targeted body part, and combat skill. A higher percentage does not equate to more damage done; for example, an 80% hit to the head/sensors will likely do more damage than a 95% hit to an armored torso. The readout also displays the overall condition of the body parts on the target.

V.A.T.S. also displays a health meter indicating the target's overall health, as well as an indicator showing the amount of damage a V.A.T.S. attack round using the player's current weapon will inflict. Note that the indicator shows the weapon's maximum noncritical potential damage that the weapon would do if the player's relevant combat skill (i.e. Small Guns) were at 100. If the player's combat skill is less than 100, they will do less real damage with each attack than what the V.A.T.S. indicator shows. On the other hand, achieving a critical hit (such as a Sneak Attack Critical) can potentially produce more real damage than the indicator shows.

There is a 15% boost in the chance for a critical hit in V.A.T.S. mode, but weapons degrade at 4 times the regular rate.

Unlike previous Fallout games, it is not possible to target the eyes or groin nor target any individual body parts in melee and unarmed combat, however you will still strike specific limbs without aiming for them, and you can still cripple and dismember enemies. Also unlike the previous games, you can't target children.

Effects
Although body part damage can be achieved through manual aiming, V.A.T.S. allows more effective targeting of particular body parts. The effects of crippling specific body parts is listed below.
 * Crippling the head will reduce overall accuracy and perception (-4) of the target. If inflicted upon the player, the screen will intermittently get fuzzy and a ring will be heard through the speakers, loosely simulating the effects of a concussion.
 * Crippling the torso will result in the target flinching far more often from shots than normal. This can also affect the player throwing off aim and stopping your attacks momentarily.
 * Crippling an arm will result in any weapon reliant on that arm for holding to be dropped, and will also drastically reduce accuracy. This is particularly evident when the player uses a scoped weapon such as a Sniper Rifle. The weapon itself is not destroyed, and they will likely just pick it back up again, unless they have another weapon in their inventory, in which case they will use that.
 * Crippling a leg will result in impaired mobility. Creatures who rely on leaping attacks (e.g. deathclaws) will no longer be able to use them.
 * Crippling the held weapon will ruin it and make it unusable, and/or send it flying out of the target's hand. Although the condition is zero and it can't be used, it can still be collected and repaired, or used for repairs. The player's weapon may be damaged by enemy fire as well. If the player's weapon CND reaches 0, it will be unequipped as opposed to flying out of the player's hands. If it is an explosive ordinance (like a frag grenade), it will explode, dealing its damage to the target holding it (and any others nearby). Grenades can be targeted by V.A.T.S. while in the air after being thrown as well.
 * Some enemies have alternate targets: Robots, ants, and others have special targetable parts that when crippled will push them into a frenzied state, where they no longer discern between friend and foe and attack anything.

Crippling any body part will result in the target momentarily pausing to clutch the now crippled body part or reel from the injury. Specific body parts cannot be targeted when using thrown explosives or melee/unarmed weapons in V.A.T.S..

Fallout: New Vegas
V.A.T.S. appears in Fallout: New Vegas, mostly unchanged from Fallout 3.

Changes

 * Every melee weapon has a special attack, which can be selected using the triangle or Y buttons on the PS3 and Xbox 360, respectively. Some moves can only be activated outside of VATS, such as the whirlwind attack with the Fire axe.
 * Unarmed weapons gain uppercut and cross at skill levels 50 and 75. These special attacks have an AP cost of 20 regardless of the weapon used.
 * You take 75% damage in VATS instead of 10%. Dying in VATS is a very real possibility.
 * The VATS critical chance bonus is 5% instead of 15%
 * There is no longer any weapon durability penalty for VATS attacks.

Fallout 3

 * When the Player starts an attack in V.A.T.S. the game may freeze to where you are only able to switch between enemies and body parts, or the sound of the attack and the radio station can still be heard but nothing happens.
 * Using V.A.T.S. when an NPC walks into an area that needs to be loaded may freeze your game.
 * If you remove a target's limbs while in V.A.T.S., then proceed to take his/her equipment, the body parts will still be shown wearing the outfit.

Fallout: New Vegas

 * The game may crash in VATS. No known fix yet. (verifies:14)


 * VATS targeting is bugged for certain guns - most lever action rifles and a few pistols: it consistently shoots high, making headshots improbable or impossible. Consistently replicable by starting a new game, adding a brush gun (id: 00121148) and .45-70 ammo (id: 0013e43e), forceaving guns to 100, and shooting at Easy Pete's head from the nearby road. Bullet impacts will appear on the windowpane behind him - and, shot after shot, will consistently be high. Modifying the gun to have perfect accuracy and/or setting fVATSSpreadMult to 0.01 will reveal that the VATS point of aim is roughly a foot high. No known fix yet.


 * Vats may sometimes cause more enemies to appear than what were nearby prior to it's activation, a character with 10 Perception who uses vats will be confused as to where these enemies appeared from and how they flanked the character (as they always appear directly behind the Courier, even if the player left only corpses in their wake). Such occurences are always tied to the use of VATS and always occur in outdoor locations, with the worst offenses being the appearance of four or more Giant radscorpions when only a single scorpion was present prior to using Vats.


 * When using Melee/Unarmed, it is possible to get stuck in a wall, You will have to reload a previous save.(Oct. 31, 2010)

Behind the scenes

 * The name " VATS " can come or may be a reference to the " RATS " (Radiation Trefoil System), a special section in the Fallout Official Survival Guide that provides additional information for each chapter of the guide.
