In a 3D video console game, whether third person or first person, the camera is of course a common problem, even without CameraScrew. In combat oriented games, keeping the camera on a target is perhaps the most important thing, hence this trope, which is when the camera locks itself itself onto a target location, moving and adjusting itself to keep the target onscreen while the player moves about. This is usually combined with directing the player's actions relative to the target, allowing them to circle-strafe around the enemy's attacks and quickly return fire.

This is most often activated by pressing a designated button, whether holding it down or turning it on or off. Other games initiate locking automatically, or apply "half" locking (with some camera control) automatically, with "full" locking when you press the right button. Some games allow switching between targets while maintaining the lock, and some games may automatically lock on to another target when the current one is destroyed.

It's not perfect, though. Locking the camera onto one enemy can limit the player's overall field of view, leaving other enemies out of sight where they can potentially attack the player from "behind", especially if there are [[ZergRush a lot of enemies at once]]. Worse, unless there is a way to choose a target before locking, the game may lock onto something ''other'' than the intended target, which can result in a CameraScrew moment where the enemy can attack or flee while the player's view is disoriented (which ''also'' applies if there are many enemies at once). As a way to mediate this, games may display an icon over the enemy/object that can be locked on to, and sometimes even allow the player to switch this icon from one enemy to the next before picking their target.

Compare FreelookButton, CameraCentering, AlwaysOverTheShoulder.

Not to be confused with MissileLockOn (although some games will overlap these), FixedCamera.

* Back in the early days of ''VideoGame/ArmoredCore'', combat is happening at a slow enough pace for players to keep a manual lock-on active. Then, during Armored Core 4/for Answer, with its massive emphasis on speedy battles, a (optional) camera lock on feature was added to help players transition. Some depend on it, more hardcore players doesn't need it.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' is either the TropeMaker, or the TropeCodifier, using a very effective form of this trope, that is still used in later 3D games in the series. The Z button not only centers your camera forward, but locks on to enemies and makes melee and ranged combat against them easier. ''VideoGame/TheLegendOfZeldaTheWindWaker'' actually introduced a number of moves that can only be done while locked onto an enemy. Conversely, ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' has a OneHitKill move that can only be used when ''not'' locked on, with [[IaijutsuPractitioner the sword sheathed]].
* ''VideoGame/MetroidPrime3Corruption'', and the other games in the ''VideoGame/MetroidPrimeTrilogy'' UpdatedRerelease, all feature manual aiming combined with its lock-on function, allowing the player to "lead" a moving target for better accuracy. Missiles and Super Missiles fired while locked on have homing capability.
* ''VideoGame/ShadowOfTheColossus'' has a "Point camera at the Colossus" button. While in some cases this is a bit superfluous (how one loses track of a tower of living stone stomping around is anyone's guess), but it helps for some of the smaller, faster, or flying ones, especially if they're out of sight, which makes it almost like a wallhack.
* In ''VideoGame/TombRaider'' and its sequels, Lara would automatically aim at anything that counted as an enemy. The camera would focus on anything that Lara was looking/aiming at. In the first three games, shooting them would cause the camera to lock on to it, continuing to follow it even if Lara lost sight of it for as long as you kept the fire button pressed. ''VideoGame/TombRaiderLastRevelation'' introduced limited forms of manual targeting that allowed the player to avert this, to an extent.
** ''VideoGame/TombRaiderAngelOfDarkness'' attempts the circle-strafing version with disastrous results.
** ''VideoGame/TombRaiderUnderworld'' allows Lara to target 2 enemies at a time.
** ''VideoGame/TombRaider2013'' completely averts this, relying entirely on the player's manual aim instead.
* StylishAction games such as ''VideoGame/DevilMayCry'', ''VideoGame/{{Bayonetta}}'', and ''VideoGame/MetalGearRisingRevengeance'' often have some form of lock-on mechanic for both regular and shooting action against enemies. In the case of shooting, it's one of the only ways to use ranged weapons quickly and accurately in such controller-based games.


[[folder: ACTION ]]

* ''VideoGame/TheMatrixPathOfNeo'' has this for aiming guns and keeping enemies in sight.
* ''{{VideoGame/Madworld}}'' features this by holding C. It's useful because there's no other way to move the camera aside from flipping it right behind you.


[[folder: First Person Shooter ]]

* ''VideoGame/{{Conduit2}}'': supplements this with iron-sight aiming like that used in most first-person shooters.


[[folder: Role Playing Games ]]
* ''VideoGame/DarkSouls'' allows the player to target on the enemies by locking onto them, which helps for dodging, maneuvering or casting spells. Starting from ''VideoGame/DarkSoulsII'', there's an auto lock on option which automatically locks onto other enemies after killing one of them.
* ''VideoGame/DarkCloud'': In the first game, it was also a requirement for using the DefendCommand.
* ''VideoGame/DualHearts'' provided a "soft" lock that lasted only while the lock-on button was held down, and a "hard" lock that remained in effect until the the player toggled it off. Both were controlled by the same button, depending on the amount of pressure the player pressed the button with.
* ''VideoGame/KingdomHearts'':
** In the first game, the player could also issue a command for Sora's allies to attack the targetted enemy.
** It is also possible for the camera to decide to lock onto something harmless like a barrel or a streetlight which can be very problematic during fights.
* ''VideoGame/MegaManLegends'' forced Megaman to stand still while locking on. The second game allowed the camera to be kept on the target regardless of which way Megaman was facing (even when he was looking the opposite way) by holding down a shoulder button.
* ''VideoGame/RogueGalaxy'' automatically targets the player's attacks towards the nearest enemy, and can automatically engage a lock-on when their attack actually connects. The player can switch from one target to another, and also control whether their allies should attack the same or different targets.
* In ''Franchise/TheElderScrolls'' series' games following the [[VideoGame3DLeap 3D Leap]] in ''Morrowind'', 1st Person and 3rd Person (in the AlwaysOverTheShoulder fashion) are both options. The games do allow you to [[FreeRotatingCamera rotate the camera angle]] when standing still in 3rd Person view, which lets you admire your character customization and gear, but if you move or draw your weapons the camera will snap right back over the shoulder.

[[folder: Platform Games ]]

* ''VideoGame/EpicMickey'' allows you to lock onto enemies if you hold the C button. The camera will then lock onto whatever has a red arrow above it. Two problems. 1) There is no easy way to switch between enemies once the camera is locked on. 2) [[GuideDangIt There is nothing in any of the documentation or tutorials about this feature.]]
* The ''VideoGame/{{Rayman}}'' series first used this in ''VideoGame/{{Rayman 2}}: The Great Escape'', and has since made appearances in updated releases of ''Rayman Arena'''s Battle Mode as well as being a key function in ''VideoGame/Rayman3HoodlumHavoc''.


[[folder: Simulation Games ]]

* Played straight and subverted in ''VideoGame/StarRaiders''. If the player turns on his Attack Computer, the screen will automatically switch between fore and aft views to track the enemy. Subverted when the player is engaging multiple ships on both sides; the screen will rapidly flip between the two views, tracking each ship as they attack.
* In ''VideoGame/WolfQuest'', the camera locks on to prey, coyotes, and bears. In older versions of the game, it was very difficult to get out of the lock-on, which was annoying if you didn't want to hunt the rabbit that just spawned in front of you, but they fixed it to make it much easier.
* ''VideoGame/AssassinsCreedII'' has this function for the player. You can lock the camera onto a specific enemy (and unlock it again) at will, which activates a few combat maneuvers and always keeps the target in sight. This can be problematic in enclosed spaces, as the camera will show the enemy, no matter what. It also tends to screw you when you fight multiple enemies at once, because it can be difficult to see when an enemy other than the focussed one attacks. The game however tries to minimize these situations by moving the camera around a bit, to give you the best view of what's going on.


[[folder: Survival Horror ]]

* In a literal use of this trope, the ''VideoGame/FatalFrame'' series introduced a "Lock On" mechanic (since the fourth game) for the Camera Obscura, which can now be used to manually lock the camera onto a hostile ghost by holding down a specific button, making it much easier to follow their erratic movements in battle. This new mechanic is practically seen as a necessity since the awkward controls for these games are often criticized.
* In the later, American-made ''Franchise/SilentHill'' games, there is often a button used to focus your character to the nearest monster, camera included. Earlier games had something similar, but it was used for attacking, only.


[[folder: Wide Open Sandbox ]]

* All the 3D ''VideoGame/GrandTheftAuto'' games have this trope unless you are using a weapon that requires manual aim, like a rifle.
* ''{{VideoGame/Prototype}}'' allows you to lock onto targets from a surprisingly long range, which makes it trivial to knock down helicopters from maybe half a mile away with a well-tossed car or some other heavy object.
