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, you can target seven different areas: the head, torso, left arm, right arm, currently held weapon, left leg, and right leg. However, there may be other points available when 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. The bar will be empty when the limb has been crippled.

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 are 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 drastically reduce accuracy and may disarm the enemy if a weapon is held in the attached hand. This is particularly evident when the player uses a scoped weapon such as a Sniper Rifle. The weapon itself is not destroyed, and the enemy can pick it up again or use another weapon from his or her inventory.
 * 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 will attack anything.
 * V.A.T.S can be used to target grenades or any other thrown explosive, whether in the enemy's hand or in the air. It will detonate if shot.

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 in principle from Fallout 3, although arguably weaker.

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.
 * 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 V.A.T.S. instead of 10%. Dying in V.A.T.S. is a very real possibility.
 * The V.A.T.S. critical chance bonus is 5% instead of 15%.
 * There is no longer any weapon durability penalty for V.A.T.S. attacks.

Fallout 3

 * 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.
 * In rare occasions, the black-and-white effect of V.A.T.S. will carry over to the normal game, rendering everything except the HUD to a permanent grayscale filter.
 * If the player falls from a great height, he/she can pull out a melee weapon and target someone below. The effect of being teleported into range loses all velocity from the fall, and negates the damage. This is most easily seen at Tenpenny Tower, from one of the balconies onto citizens below.

Fallout: New Vegas

 * Upon tapping the VATS button, the player may only hear a click and no change in gameplay, as VATS does not activate. This problem can last for up to several minutes (easily enough to hinder any player reliant on the VATS system), at which point VATS once again becomes available. This issue appears to be a problem with the L2 & R2 button mapping.  Remapping VATS to a different button can resolve the issue. If this doesn't work, you can turn off the controller and turn it on again or even quit the game and get back in.


 * Game consistently freezes upon entering VATS. Might have something to do with deleting the the Game Data post-patch, reinstalling, playing for a bit without the patch (to get into the Abandoned BOS Bunker), then reloading the patch.


 * 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. This bug also seems to occur with the Hunting Revolver.


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


 * By tapping the VATS button (regardless of whether an enemy is around), the game freezes to the point in which a manual restart is necessary. Restarting (from the same save point) has not fixed the glitch, but loading an earlier save might. Try deleting system cache as i think it could be the patch affecting this (not confirmed).


 * After choosing where you want to attack at your enemy and pressing the button to attack him, your character may do nothing and stay still during the slow-motion, while your enemy attacks you. This lasts a couple of seconds and then the game returns to normal.


 * On very rare occasions, your character may not fire after queuing up the attacks, forcing you to reload a previous save.


 * At close to medium range, VATS may simply refuse to register attacks but will go into cinematic view. The Player Character will simply stand still while being attacked. Note: The enemies will go back to normal speed which means if you are in a difficult fight, you just might die. After several seconds however, the screen may revert to normal view.


 * After entering VATS, and skipping the kill camera, your game may be in slow motion for about ten seconds. This won't prove any difficulties, everything will be in slow motion. This may also occur if you have the cinematic kills on, and usually occurs around areas with cliffs, apparently.


 * While attacking in VATS, only the target and player will be in slow motion. Any other enemies in the area will move and attack at normal speed, making you a prime target for the duration of your attack.
