[[AC:FirstPersonShooter]]
* As mentioned, {{Rocket Jump}}ing is a common technique exploiting the blasts from explosive weapons.
* ''VideoGame/GoldenEye1997'' and ''PerfectDark'' have a knock back for the player if they get shot. This also stops the player from shooting for a brief second. Combine this with several enemy soldiers and you're bound to lose more than half your health while unable to to fire back. Luckily, the enemy AI is programmed to stop firing for a moment and then resume.
*** Perfect Dark Zero also has it, making enemies that duel-wield machine pistols especially dangerous, with the possibility of stunlock.
** The ''MedalOfHonor'' games also have hit-stun. If an enemy catches you off-guard at close range with an automatic weapon on Hard difficulty, you may be stunlocked. Conversely, due to the use of HitScan, the knockback [[TheComputerIsACheatingBastard doesn't affect the enemy's aim]], so they can continue shooting at you while apparently flinching. The snipers in ''Allied Assault'' not only deal the most damage and knockback of all mooks, but they also fire at a higher rate than the rifle infantrymen.
* Shotgun Z-Secs and Pinky Demons in ''[[VideoGame/{{Doom}} Doom 3]]'' both deliverable sizable knockback, the former bordering on BlownAcrossTheRoom, and can result in {{stunlock}}.
* In ''VideoGame/TeamFortress2'' regular attacks have an amount of knockback generally proportional to damage and only something like the Heavy's minigun does enough damage for this knockback to impede movement instead of just messing with aim. There are some special cases which do much more: explosives, the Scout's Force-A-Nature, sentry guns (which can be even harder to deal with than its damage, especially since the default [[LimitBreak Ubercharge]] does not protect against knockback), melee {{Critical Hit}}s, and the Pyro's [[AttackDeflector airblast]] (which does nothing ''but'' knockback). Probably the most bizarre thing is that damage over time (fire, bleeding) causes ''upward'' knockback for the sake of messing with the user's aim. The Soldier's Mantreads and the Quick-Fix's Ubercharge reduce knockback by 75% and 100% respectively (though the Mantreads do not protect against airblasts).

[[AC:ActionAdventure]]
* ''Franchise/TheLegendOfZelda'' has various enemies whose main power is having more knockback than most, and ''VideoGame/TheLegendOfZeldaOracleGames'' featured a [[RingOfPower ring]] that reduced knockback.
* The final segment of the FinalBoss of ''VideoGame/BeyondGoodAndEvil'' suddenly ramps up the effects of the game's knockback--while present-but-negilible before, even a small attack will now result in the heroine getting totally decked. During one sequence of attacks, it is entirely possible to get "stunlocked" and make the fight {{Unwinnable}} until you inevitably die and get sent back to the checkpoint.
* ''VideoGame/DeadlyTowers'' has Prince Myer get knocked in whatever direction is opposite the way he's facing quite a distance without a way to stop himself. Unfortunately, this game also features BottomlessPits...
* Explosive weapons and melee attacks  in ''VideoGame/{{Iji}}'' cause knock back, while weaker weapons cause flinching. This applies to both enemies and the protagonist. The knock back from some weapons reaches BlownAcrossTheRoom levels - Many secrets in the game can only be obtained by taking advantage of this.

[[AC:FightingGame]]
* Many fighting games feature "grapple" and "throw" moves, and knocking an opponent out-of-bounds can trigger a RingOut in various titles.
* Some fighting games like VideoGame/GuiltyGear have a pushblock mechanic that allows a defender to enter a state where the opponent is pushed away when their physical attack is blocked.
* The ''VideoGame/SuperSmashBros'' series is based ''entirely around'' {{Ring Out}}s; characters do not have depletable HP but instead receive greater knockback as they take damage, until they are inevitably thrown from the arena.
* Some games such as later ''KingOfFighters'' entries take Knockback to an extreme, making some attacks capable of bouncing an opponent off the wall[=/=]floor in order to extend combos.
* A key game mechanic in ''DissidiaFinalFantasy'', in the form of Wall/Floor/Ceiling Rush. Essentially--many attacks send the opponent away from the fighter at high velocity. If an attack has the ability to wall rush, and there's a wall somewhere along the victim's trajectory, they'll slam into it for extra damage (base value of one-half of the damage done by the original hit in ''Dissidia'', one-quarter in ''Duodecim''). Interestingly, various attacks have various 'likelihoods' of wall rush--a lot have zero chance of rushing, no matter if your opponent is right up next to the wall/ceiling, some have wall rush for a certain amount of distance (e.g. Bitter End can wall rush, but the opponent recovers if there's no wall for a long way), and a very amusing few (Nightglow, Shadow Bringer, and Cross Slash, for few) basically have guaranteed wall rush--so long as there ''is'' a surface to slam into, the opponent ''will'' do it--even if the closest wall is [[PunchedAcrossTheRoom hundreds and hundreds of meters away]].
** In fact, Cloud's fighting style is aggressively dependent on Wall Rushing. Almost all of his skills have a high chance of Wall Rush, and his most basic attacks will generally send the opponent flying into a wall (or enable a chase scene, if the wall is too far away). Abusing this mechanic is his ''raison d'etre'': he's not just hitting you hard, he's hitting you hard, then slamming you into a wall for more damage while he rushes after you to rinse and repeat.

[[AC:{{MMORPG}}]]
* VideoGame/WorldOfWarcraft featured knockbacks by various NPC mobs and bosses from when the game was first released, but players didn't get access to them until Patch 3.0, the ''Wrath of the Lich King'' expansion, when a small handful of abilities were given to various classes that would knock [=NPCs=] or other players back. [[TheAIIsACheatingBastard NPCs don't take falling damage and can run up some sheer cliffs]] so {{Knockback}} abilities are generally underpowered against them, but in certain limited circumstances {{Knockback}} effects can be very, very powerful in PvP.
** Humorously, they can get so annoying in dungeons (they disrupt positioning and can knock enemies into reinforcements) that several classes have the ability to turn off the knockback aspect of the spell through the use of a glyph (Mages, Druids, and Shaman, for those who care.)
** The flinching ability is available from the start however, in the form of various stuns as well as interrupts.
* ''VideoGame/CityOfHeroes'' has three versions: knock back, knock up, and knock down. Almost all melee classes have a power that resists these effects. There also exist enhancements that provide the player with resistance to it, which are in very high demand as most players hate being knocked around by enemies. There also exist enhancements for increasing the knockback in your own powers.
* As an action [=MMO=], ''DragonNest'' practically requires players to exploit the various forms of this trope as even {{Mook}}s can easily do the same. Resistance to this trope can be a {{Gamebreaker}} especially in PVP.
* StarWarsTheOldRepublic has it in various forms. From the simple 'interrupt' ability that interrupts abilities being cast or channeled (and preventing it from being cast again in a few seconds), then there are 'stun' and knock down abilities that is as good as it sounds (but also on very long cooldown), to knockback abilities that sends the enemies flying.

[[AC:RealTimeStrategy]]
* While ''VideoGame/{{Warcraft}} III'' doesn't feature knockback, the trope's omnipresence is such that it's a very rare (custom) map that doesn't have this mechanism (such as ''VideoGame/DefenseOfTheAncients'' and its variants).
* DawnOfWar has knockback for artillery and some units. Justified for some (SuperStrength, PsychicPowers, etc), but it does get a bit ridiculous when the Kroot (lanky hollow-boned ''bird''-men) are upgraded to knockback units such as seven-foot-tall {{Power Armor}}ed SpaceMarines with the same ease as [[MadeOfPlasticine ordinary Guardsmen]] and [[OurGoblinsAreDifferent Gretchin]]. Also a fallen unit ordered to move will do so while playing their "get up" animation, so they end up gliding majestically along the ground before getting up.
* ''Myth 1'' and 2 have a flinch mechanic that is fairly central to gameplay as it allows certain rock-paper-scissors balancing. For example, the fast but unarmored Berserks can often kill heavily armored Warriors by whaling on them fast enough that the Warrior can't get a swing in from all the flinching. However, the same Berserks have a tough time against archers, as being hit causes the Berserk to stop running while he flinches--making him an easier target. Those heavily-armored Warriors are less likely to take damage from arrows, and still less likely to take enough to flinch.

[[AC:ThirdPersonShooter]]
* ''GearsOfWar 2'' and 3 implement a "stopping power" system where being shot slows the player's movement toward the shooter. This was added to prevent players from charging through a hail of machine gun fire for a close-quarters execution with a shotgun. In addition, smoke grenades in 3 (and post-patch 2) cause a flinch effect, while in 1 and pre-patch 2 cause full-on knockback, though they deal no actual damage in either case.
* In ''{{PN 03}}'' the amount of knockback varies with the amount of damage inflicted by an enemy attack, with the strongest attacks blowing Vanessa [[BlownAcrossTheRoom clear across the room]]. In some cases, Vanessa mysteriously is knocked ''forward''.

[[AC:TurnBasedStrategy]]
* {{Hoshigami}} has an entire game mechanic centered around knocking enemies into a chain of allies to incur massive damage and have a chance at stealing an item, but unfortunately setting up such a chain leaves your party very vulnerable so it's only useful for eliminating the last enemy on a map.
