Let's be honest, anyone can get a couple kills by just mashing random buttons and hoping for the best. It takes an entirely different class of player to continue getting kills without dying or even taking damage. Because of this, many VideoGames appropriately reward players who can perform these feats with special bonuses, exclusive titles, or even hidden content.

May overlap with AwesomenessMeter, IdiosyncraticComboLevels, or ScoreMultiplier if an unbroken kill streak contributes to filling it. Compare UnstableEquilibrium, which is also a means of rewarding good players by helping them get even better scores.

!!Examples:
* While ''VideoGame/AssassinsCreedBrotherhood'' doesn't feature any extra bonus for its Kill Streaks (actually named that, it's a feature where you can one-hit-kill an enemy who is in range of you when you kill another), its VR training does have a survival mode that counts how many enemies you can kill before taking damage.
** ''VideoGame/AssassinsCreedIII'' plays this straighter - some EliteMooks are normally able to counter Kill Streaks, but if you have built up enough normal kills, they will be scared into vulnerability.
* ''[[VideoGame/BattlefieldBadCompany Battlefield Bad Company 2]]'': Rewards players with medals for Kill Streaks 6 or 8 kills long.
* ''{{VideoGame/Bug}}!'' has ''hit streaks'', every time Bug successfully jumps on an enemy without landing on the ground, [[http://www.youtube.com/watch?v=i8boh2TsnG0 he gains more points]] (1 hit- 50, 2 hits- 100, 3 hits- 200, 4- 500, 5 or more- 1000)
* ''VideoGame/{{Borderlands}}'' awards [[ExperienceBooster XP bonuses]] for consecutive kills with no more than a few seconds between each. The top level is called "Conveyor of Death" and requires 25 kills.
* Beginning with ''Call of Duty 4'', games in the ''VideoGame/CallOfDuty''/''VideoGame/ModernWarfare'' series have deployable Kill Streak rewards for reaching certain streak counts in multiplayer:
** ''Call of Duty 4: ModernWarfare'' has three: a [[EnemyDetectingRadar UAV]] (3), an [[DeathFromAbove Air Strike]] (5) and an [[GunshipRescue Attack Helicopter]] (7)
** ''Call Of Duty: World at War'' also has three: a [[EnemyDetectingRadar Recon Plane]] (3), an [[DeathFromAbove Artillery Strike]] (5) and [[AngryGuardDog Attack Dogs]] (7)
** ''ModernWarfare 2'' introduces Death Streaks as well, giving a player who is suffering a string of losses a helping hand to turn the tide. While the player can only equip three Kill Streak rewards at a time, they have an expanded list to choose from, all the way from [=UAVs=] (3) and sentry guns (5) up to {{EMP}}'s (15) and [[NukeEm Tactical Nukes]] (25) (AKA, 'The "I Win" button')
*** This game's utilization and prevalence of streaks in particular [[BrokenBase broke the base]].
** And there's even a reward for players who kill others who are just a kill short of a Kill Streak reward (Buzzkill).
** ''VideoGame/CallOfDutyBlackOps'' also has an expansive list of Kill Streaks, such as a deployable SAM launcher that can destroy opposing killstreak rewards, and an SR-71 Blackbird, which is a better version of the Spy Plane which cannot be shot down.
** ''Modern Warfare 3'' expands on this with "Strike Packages", killstreak rewards tied to your custom classes - you can choose an Assault package to get the usual directly-offensive killstreak rewards, a Support package to get ''point''streaks instead that don't reset upon your death and allow you to both help your team survive longer and see the enemy better, or a Specialist package to acquire additional perks as you make kills. Regardless of your streak setup, there's also a hidden fourth kill/pointstreak, the "M.O.A.B.", at 25 kills, which is much like the Tactical Nuke but less abuseable - it kills every enemy on the map, but rather than ending the game at that, just gives doubled experience to the team that called it in for the rest of the match.
** ''VideoGame/CallOfDutyBlackOps2'' switches to a "scorestreak" system, wherein streak rewards are given based on how many points you make in a life. Functionally it's the same as the killstreaks from ''Black Ops'', except you can now gain the same streak reward multiple times in one life.
* ''VideoGame/TheClub'': Designed around this.
* ''VideoGame/DevilMayCry'': Awards you for killing multiple enemies ''[[NintendoHard without taking any damage at all]]''. Moreover, if you use the same moves too often, the counter stops rising until you shake it up.
* ''DinoCrisis 2'' rewards you handsomely for completing a kill streak in a given area, and throws a '''huge''' bonus on top of that for scoring one without taking any hits. Since the points are used as in-game currency to buy weapons, health and ammo, you have twice the incentive to avoid enemies, but you also have to be aggressive and expose yourself to more danger so you can rack up the kill streaks needed to make it worth your while. You can eventually purchase an upgrade that allows the timer to tick down much more slowly between kills, allowing you ease up on the pace and play more defensively.
* ''VideoGame/Divekick'': calls out your consecutive headshot streaks. "Double Kill" for two, "Multi Kill" for three, "On a Rampage" for four, and "Total Domination" for a perfect 5-headshot streak. You'll get a PSN trophy if you pull off Total Domination in a ranked match.
* ''VideoGame/DonkeyKongCountryReturns'': defeating 3 enemies in a row will reward 1 banana coin and more for every defeat after that.
* This is a core scoring mechanic of the ''VideoGame/DonPachi'' series. In general, defeating enemies in a row is worth bonus points, while letting your combo meter run out or getting hit breaks your chain. In later games, each subsequent enemy in a chain is worth its base value plus the base value of all previous enemies in the chain combined. This can lead to some [[PinballScoring pretty ridiculously big numbers]]; for example, a perfect chain through stage 5 ([[NintendoHard much easier said than done]]) in ''[=DoDonPachi Dai-Fukkatsu=]'' with some good Hyper Counter usage will result in the last couple enemies in the stage being worth over 100 million points each.
* In ''VideoGame/FinalFantasyXII'', you can chain enemies of the same type. Killing a certain amount will raise your chain level, and each level will increase the chances of getting a rare drop.
* The AnnouncerChatter in ''Franchise/{{Halo}}'' uses [[{{Crunchtastic}} fictional adjectives involving the word "kill"]].
* In ''VideoGame/HouseOfTheDead: Overkill'', you can climb up the violence ladder the more kills you get without missing or being hurt. Extreme Violence, Hardcore Violence, Ultra Violence, Psychotic, and finally ''Goregasm'' (which is accompanied by a waving American flag) - each condition increases the amount of points a kill will net you, and as such a long Goregasm is a definite requirement for a high score.
* In ''VideoGame/LeagueOfLegends'', racking up a killstreak without dying will cause the announcer to declare after 3, 4, 5, 6, 7 and 8+ kills respectively: killing spree, rampage, unstoppable, dominating, godlike and legendary. Getting a bunch of kills quickly after one another has her announce double kill, triple kill, quadra kill and penta kill. This provides no actual benefit to the player, though, and it instead [[MoneyMultiplier raises the amount of gold]] their enemies will get from killing ''them'' as their streak rises. Likewise, dying over and over reduces gold gained from you by 70% each time.
* In ''Franchise/{{Pokemon}}'', the ability Moxie increases the Pokemon's Attack by 1 stage for every opponent it defeats.
* In ''VideoGame/{{Purple}}'', [[GoombaStomp stomping enemies]] continuously without landing will yield bigger amounts of points and eventually 1-ups.
* In ''VideoGame/ResidentEvil4'', in the Mercenaries mode, the more kills in a row you get, the more points you get, which in turn can be used to get unlockables.
* ''VideoGame/RatchetAndClank'' games since the second one feature a [[MoneyMultiplier bolt multiplier]] (which multiplies the amount of bolts, the in-game currency, enemies drop) on a NewGamePlus. It increases by one for every time you kill an enemy up to a maximum of x20, and resets to x1 if you get hit.
* In the {{Namco}} arcade games ''VideoGame/TimeCrisis'' (beginning with ''Time Crisis II'') and ''RazingStorm'', landing hits increased your combo meter, but it would get reset if you got damaged. You could get it ludicrously high if you manage to avoid all damage.
* ''VideoGame/RedFaction: Guerrilla'' awards an achievement for achieving 25 kill streaks throughout the game.
* Getting a kill streak actually figures into ''SewerShark'''s plot. You need to pull in higher and higher numbers of "pounds of tubesteak" to maintain your job as a sewer jockey and, thereby, earn a ticket to Solar City as a reward. Later on, critters attack you to drain your energy reserves, meaning you're just shooting them to live longer... and ''later'' on, they start {{One Hit Kill}}ing you, further boosting that second incentive.
* ''[[VideoGame/SoulSeries Soul Calibur 2]]'': Features a "Survivor" mode based on killing multiple opponents without dying.
* As seen in the trope image, many installments of the ''Franchise/SuperMarioBros'' series give increasing point bonuses, and eventually [[OneUp extra lives]], for consecutive kills, whether it be multiple {{Goomba Stomp}}s or using a shell. This can be exploited to gain InfiniteOneUps.
* Some achievements in ''VideoGame/TeamFortress2'' involve this (often with extra conditions, such as using a particular weapon).
** The Heavy's [[http://wiki.teamfortress.com/wiki/Killing_Gloves_of_Boxing Killing Gloves of Boxing]] and Sniper's [[http://wiki.teamfortress.com/wiki/Cleaner%27s_Carbine Cleaner's Carbine]] guarantee critical hits and mini-crits respectively after a kill, and reset the duration for consecutive kills with the same weapon within that time.
** The Sniper's [[http://wiki.teamfortress.com/wiki/Hitman%27s_Heatmaker Hitman's Heatmaker]] can fill its Focus meter during Focus mode through kills and assists.
** In the Mann vs. Machine update, the Demoman's and Spy's upgrades for their melee weapons allow critical hits after a kill for 2 seconds.
** The Two Cities update introduced Killstreak Kits, which you can apply to your weapons. The standard version just tracks your kills, the Specialized version gives a colored sheen that grows in intensity every 5 kills, and the Professional version gives your eyes particle effects after a 5+ killstreak.
* One of Respawn Entertainment's goals in ''VideoGame/{{Titanfall}}'' is to allow all players access to the titular MiniMecha. The quicker the player scores kills and complete objectives, the faster they can call their [[AMechByAnyOtherName Titans]] to the battlefield.
* ''VideoGame/TransformersWarForCybertron''
* ''VideoGame/UnrealTournament'': Features special names for the various numbers of kills, which the announcer calls out: [[MemeticMutation M-M-M-M-MONSTER KILL!!]] and in later games, "HOLY SHIT!" It also reserves "MONSTER KILL!!" for sufficiently large combos. Huge runs without death end up with "GODLIKE!!" and in later games "WICKED SICK!".
** Specifically:
*** Announcements for rapid kills: Double Kill, Multi Kill, Mega Kill, Ultra Kill, Monster Kill. Later games add Ludicrous Kill and Holy Shit.
*** Announcements for killstreaks without dying: Killing Spree, Rampage, Dominating, Godlike. Later games add Wicked Sick.
*** ''VideoGame/UnrealTournament2004'' adds 5-kill-streaks with specific weapons: Bio Hazard for Bio Rifle, Flak Monkey for Flak Cannon and Head Hunter for five [[BoomHeadshot headshot]] kills with the Sniper Rifle.
** The ''VideoGame/WarcraftIII'' map/mod ''VideoGame/DefenseOfTheAncients'' uses these sounds as well.
** Ditto for some server-side ''VideoGame/{{Counter-Strike}}'' mods.
** Ditto again for ''VideoGame/TeamFortress2'' server-side mods.
