''darkSector'' is a ThirdPersonShooter developed by Creator/DigitalExtremes, and released for Platform/PS3 and Platform/Xbox360 on March 25th, 2008, with a [[Platform/IBMPersonalComputer PC]] version following exactly a year later.

You play as Hayden Tenno, an operative for an unnamed American intelligence agency. He is sent to the fictional Soviet nation of Lasria to gather information on a mysterious [[TheVirus epidemic]]. Of course Hayden has a DarkAndTroubledPast, and is [[TrueArtIsAngsty angsting]] about his current assignment, afraid of being infected or reliving his past misdeeds. Obviously, TheVirus is on hand to give him superpowers (as viruses that infect the protagonist are prone to doing).

Gameplay revolves around Hayden using normal weapons and his infected powers to confront enemies: other infected and the Lasrian army trying to contain the infection. Hayden's most important (and gameplay impressive) power is the use of the Glaive, a sort of three pronged ninja star he can use to do pretty much anything Series/{{Xena|WarriorPrincess}} can do with her Chakram. Gameplay also includes taking over Lasrian military hardware and turning it against them and some minor physical puzzles that can be solved using Hayden's powers.

The original concept for ''darkSector'' was later reused for Digital Extreme's free-to-play sci-fi shooter, ''VideoGame/{{Warframe}}''.

!!''darkSector'' provides examples of the following tropes:
* AllThereInTheManual: The developers came clean about the game's plot; apparently, as they were editing the game down, the only people they had to run the plot past were already familiar with it, so the huge omissions (Hayden having congenital analgesia, explaining why he alone isn't driven mad by the infection; his history with Nadia; Nadia and Viktor being related; the Stalker being Yargo's daughter, who was infected in the first outbreak in the 80s, which is why he knows it's "very old" and why [[EvenEvilHasLovedOnes it doesn't kill him while waiting for Hayden]]; etc.) were never picked up on. Their previous game, ''VideoGame/{{Pariah}}'', suffered from the exact same "accidentally left the plot on the cutting room floor" problems.
* AKA47: An odd example; almost all the weapons are modeled after one weapon but named as if they're giving this treatment to a ''different'' weapon that would fill the same role, as if the names were settled on long before the models - and, interestingly, almost all of the fake names are based on Russian weapons in particular. Hayden's Heckler & Koch Mark 23 is called the "Tekna 9mm" after the SR-1 Vektor pistol, the "Vekesk Micro" is a Klin PP-9 named after the SR-2 Veresk submachine gun, the Hammer 1895 is a Webley Mark IV named after the Nagant Model 1895, and so on. Exceptions to the usual rule are the two shotguns, a cut-down Mossberg and a full-size H&K FABARM, which are both named after different variants of the Armsel Striker, and exceptions to the trope itself are the AKS-74U (mostly - the in-game name cuts off the last U, which is a different but still related and extremely similar weapon) and the RPG-7.
* AnArmAndALeg: Your Glaive can lop limbs off enemies. This is more easily done with a Power Throw.
* AwesomeButImpractical: The Trooper Gun, mostly by slowing you to a crawl. Also the magnum and sniper rifle; they both deal heavy damage but draw from an absolutely tiny pool of rare ammo and are relatively inaccurate, even with upgrades (the sniper rifle in particular due to SniperScopeSway).
* {{BFG}}: The space-suited Lasrian Elites use the "[[ExactlyWhatItSaysOnTheTin Elite Trooper Gun]]," a massive multi-shot rocket launcher with an underslung pneumatic gatling gun. In game terms, this works out as "RPG-7 with shorter reloads and one of those godawfully inaccurate mounted guns stuck underneath," thus neatly removing the weaknesses of both the RPG (no backup weapon to safely deal with trash) and the mounted machine gun (piss-poor accuracy matters a lot less when you can just move the gun up close and personal).
* BigBadEnsemble: Mezner and the A.D., both acting as some combination of the GreaterScopeVillain and TheManBehindTheMan. (Mezner has control of the active Technocyte infectees and plans on waking up ancient ones, the A.D. cuts a deal with him to keep doing his thing under Agency supervision.)
* BoringButPractical: The Vekesk Micro is about the best all-around gun in the game, using plentiful ammo with a huge stock and doing respectable damage. It's also a one-handed weapon, so it doesn't restrict use of the Glaive like the Korbov [=TK6=], which is otherwise a straight upgrade no matter what weapon you used previously.
* BossInMooksClothing: Lasrian Elite Troopers are GiantMook enemies inside bulletproof PoweredArmor spacesuits, equipped with a combination minigun and rocket launcher. There are about 5 of them throughout the entire game.
* CamelCase: The game's title is formatted as ''[=darkSector=]''. This is also used throughout the game's interface; for example, the "New Game" option in the main menu is shown as "[=newGame=]".
* ChargedAttack: Charging the Glaive can result in a Power Throw that does four times the damage and can destroy certain chains. This is a bit tricky to execute, as you have to release the charge with perfect timing right as it hits its peak; holding it any less or any more will result in a normal throw instead.
* CursedWithAwesome: Hayden, even upon learning how useful the powers he gets from the virus are, does ''not'' like them, and thinks they are what he "deserves" for being what he is: a state-sanctioned psychopathic killer.
* CutscenePowerToTheMax: Hayden's C4. You're supposed to place a bunch of charges across the prologue, but the game only gives this a passing mention and never actually requires you to do so - ergo, the block he throws in Viktor's lap in a cutscene is enough to destroy a sprawling complex that takes up most of an island on its own. A block of it you later find during actual gameplay barely destroys a single door.
* DeliberatelyMonochrome: The first level is desaturated almost to the point of being in black and white. It's not really all that clear why; color immediately comes in after Hayden takes the hit that infects him in the cutscene at the end of it.
* DisabilitySuperpower: While [[AllThereInTheManual you'd only know from reading the previews since it isn't mentioned in game]], Hayden has a condition called [[http://en.wikipedia.org/wiki/Congenital_insensitivity_to_pain congenital analgesia]]; this results in insensitivity or indifference to pain, and is how he survives infection with TheVirus without going mad. He's a fairly unrealistic depiction of a sufferer, given he hasn't managed to hideously damage himself accidentally during childhood. He appears to specifically have the "indifference" rather than the "insensitivity" version - this means the sufferer is aware of pain as a sensation associated with personal harm, but it does not ''hurt'' as it does for a non-sufferer. His complaining about a headache (due to his exposure to the virus) seems to reflect that he finds the sensation annoying, while the other cases where he "feels pain" are mechanical reactions to extreme physical trauma, e.g. the kind from the infection that drives everyone else mad.
* EldritchAbomination: Technocyte organisms get larger and StrongerWithAge, and it's heavily implied that after a few centuries they become outright huge monsters. Mezner's plan is apparently to send out a signal that will go across the globe and wake these guys up from their ancient slumber deep beneath the ocean depths.
* EnemyCivilWar: Hayden is targeted by other infected and the Lasrian army, both of whom were created by/work for Mezner. But they don't like each other. In fact, they are just as likely to kill each other as they are to try and kill Hayden.
* EvenEvilHasLovedOnes: If the rumours about the stalker being [[spoiler:Yargo's daughter are true, then the scene where the stalker uncloaks behind Yargo and proceeds to attack Hayden all the while leaving Yargo alone could count]].
* EverythingFades: Rather inconsistent even despite the fact that the straight cases are clearly an intentional design decision rather than due to memory limitations. Bodies of soldiers persist, and certain types of infected enemies will remain, but others melt away into nothing (assuming they don't [[ActionBomb explode]] upon death) - except for limbs removed from them, which will persist long after the main body has withered away.
* FeelNoPain: It's never mentioned or established in actual gameplay, but Hayden takes the infection lightly compared to [[DrivenToMadness everyone else]] because of a congenital condition making him unable to register pain.
* FireIceLightning: Throwing the Glaive at sources of electricity, fire, or ice will temporarily imbue it with that element. This massively increases its damage, allows you to create a large elemental explosion (once you unlock that ability), and can be used to solve environmental puzzles (using electricity to power generators, fire to burn obstacles, ice to put out fires and freeze water).
* GasMaskMooks: All of the Lasrian soldiers wear gas masks, save the ones who wear space suits.
* GodzillaThreshold: Perhaps the only thing more horrifying than what the Lasrian military does in response to the infection (a slideshow you can find early on mentions that eliminating the civilian population around an infection site is one of their ''first'' priorities) is the strong possibility that it is actually ''justified'' considering the danger of said infection.
* GoryDiscretionShot: In one cutscene, Nadia is interrogating Yargo about how to open the vault. She slides her thumb over his eye, and asks him again. The camera shifts to show the back of his head as she starts to press, and the screen fades to white as [[EyeScream a squish is heard and he screams in pain]].
* GunsDoNotWorkThatWay:
** Hayden's "Tekna 9mm" and "Tekna Burst" have "Cal .45 Auto" stamped on the slide.
** The "Clip Extender" upgrade works on anything - even the break-open, breech-loading shotgun that very clearly could not hold more than two shells in reality without extensive modification to add an actual magazine.
** "Ok, how about the C4?" "For Yargo, I'll give the Semtex..." Erm... Semtex is not C4.
* TheHerosJourney: Referenced directly and played straight.
* HurtFootHop: A particularly extreme case in that it involves [[AnArmAndALeg outright severing the foot]]: if you slice off an enemy's leg with the Glaive, they will sometimes hop in place a few times before dying from blood loss.
* HyperspaceArsenal: Averted; you can see exactly what weapons Hayden is carrying, aside from grenades. Additionally, you can carry at maximum three guns, but can only stow two; you have to drop the third to switch back from it.
* ImpossiblyCoolWeapon: The Glaive, a three-pronged blade that grows out of Hayden's infected arm, can be thrown with ludicrous precision, and eventually gets upgrades that let him [[PrecisionGuidedBoomerang guide it after throwing]], throw out temporary energy shields, and absorb energy from extreme heat, cold or electricity to immolate/freeze/electrocute what it hits or hit everything in a certain radius with a blast of that energy. Granted, some of this is more borne from Hayden's infection, which produced the Glaive in the first place.
* InterfaceScrew: Enferon turns the screen various vile colours until you get the proto armor. Also, while smoke from the Jackal is supposed to show you when it's damaged, the Jackal ''always'' gives off a ton of smoke, even at 100% health.
* InvisibleMonster: Chromas are a variant of the Stingers with the added ability to turn invisible.
* JumpScare: In Chapter 7, when you go into the train tunnel, a monster will pop out of a hole in the wall with a loud roar and grab you, forcing you into to PressXToNotDie.
* KryptoniteFactor: Enferon, a chemical which is only a minor irritant to humans but will kill infected Technocyte creatures quite quickly. You can find weapon add-ons to lace your own bullets with Enferon, which nearly doubles the power of your bullets and poisons infected enemies. Human enemies will also occasionally hurl Enferon grenades at you after the first chapter. [[spoiler:The special suit that Hayden obtains in Vozro protects him from Enferon.]]
* MeleeATrois: You have the player vs. the Infected vs. the Lasrian Military.
* MirrorBoss: Your final fight against TheDragon. By this time, Hayden's infected powers have fully developed and he is now a match for it; he's even got a cool suit of techno-organic armor just like the Nemesis. It also shows off that it's capable of doing a few things you thought you had exclusivity on, such as [[ThrowingYourSwordAlwaysWorks throwing its blade]] and imbuing it with lightning.
* NoNameGiven: The AD is never called by his real name (Dixon) at any point in the released game; the fact that he ''has'' a name is primarily limited to pre-release material, though it's also on a nametag on his chest when he shows up at the end, if you look closely.
* NoodleIncident: Large chunks of the backstory are treated this way, on account of the issue listed under AllThereInTheManual. It's mentioned the infection got out and was contained in the past, but no details are given. Hayden went psycho and killed a bunch of people in a previous mission, but no details are given. Nadia and Hayden have history, but no details are given. In fact, everyone in the facility seems to know Hayden personally, with Yargo having been briefed before meeting Hayden and Mezner having looked up Hayden's record specifically.
* OffWithHisHead: You can decapitate enemies by throwing your Glaive at their heads. There are even achievements for decapitating a lot of enemies and for [[OneHitPolykill getting two decapitations with one throw]].
* OurZombiesAreDifferent: Whilst the older Technocyte infected tend to be superhuman type things, superpowered animals or {{Eldritch Abomination}}s, the basic infected enemies are essentially metal-skinned zombies, complete with {{zombie gait}}, moaning and the occasional scene of them seemingly eating corpses.
* PlotHole: Many. See AllThereInTheManual for why.
* PowerCopying: Many of Hayden's powers wind up being similar to the Nemesis that infected him, but there's a few times where he copies the abilities of another enemy he's defeated, most specifically gaining "[[{{Invisibility}} Shift]]" from the giant Stalker that turns invisible.
* PrecisionGuidedBoomerang: ''Literally'' guided with the Aftertouch ability.
* PuzzleBoss: All of the bosses have elements of this, but the Nemesis is the most obvious one, as it cannot be harmed by normal weapons and has to be killed through a very specific set of actions.
* RecurringBossTemplate: Many highlights of the Stalker -- spying on you as you try to catch fleeting glimpses in the shadows, turning invisible and sneaking up on you for devastating melee attacks, stealing its tools for yourself after you kill it -- would later get reused by the boss of the same name in ''Warframe''.
* RevolversAreJustBetter: The revolver is by far the most powerful pistol in the game. This appears to be because it loads and fires ''sniper rifle rounds''.
* SamusIsAGirl: It turns out that Mezner's Manga/{{Guyver}}-looking [[TheDragon Dragon]] is [[spoiler:Nadia]] inside a Technocyte suit.
* ShoutOut: The Glaive is named after the similar-looking weapon from the movie ''Film/{{Krull}}''.
* SpiderTank: Lasria's Jackal tanks are more "dog tank", but they still have legs.
* SwordAndGun: A weird variant, considering the Glaive is nothing like a sword, but this is basically how sidearms are used after Hayden gets infected, gun in the left hand and Glaive in the right.
* TacticalSuicideBoss: The Nemesis. He starts the battle with a shield that can block absolutely everything you can bring to bear. The only way to break his shield is with an electrically-charged Glaive, but there's no exposed wiring in the room. Cue the Nemesis [[TooDumbToLive charging up his blade with electricity,]] only to have you dodge his throw and [[HoistByHisOwnPetard use his blade to charge yours.]]
* ThereIsNoKillLikeOverkill: In a cutscene, Hayden shoots Viktor Sudek in the head. He then dumps a C4 demolition charge in his lap.
* UniversalAmmunition: Ammo is generically split between ammo for pistols (the two handguns), assault rifles (anything automatic), shotguns, and "Magnums" (the sniper rifle and revolver), with little regard for chambering - most egregiously, the 9x18mm Klin PP-9 shares ammo with the 5.45x39mm AKS-74U and 5.56x45mm [=G36C=], and the .455 Webley revolver shares ammo with the 7.62x51mm [=M1A=].
* UnusableEnemyEquipment: To begin with, Hayden can pick up any enemy weapons he likes; however, once infected the sensors on the weapons destroy them after a brief period (generally about fifteen seconds, though on one occasion a sniper rifle has a limiter that lasts for a full minute) if he uses them. Fortunately, weapons grabbed in this manner have separate ammo pools from what's available for your normal weapons, so it's not entirely pointless to avoid them in favor of your personal weapons bought from the black market.

* WasOnceAMan: Although we already know going in that [[TheVirus all of the Infected were once human]], there are subtle implications that [[spoiler:the Stalker boss was Yargo's daughter]].
* WeakTurretGun: The massive [=DshK=] / NSV hybrid mounted guns are practically useless, firing patterns so ridiculously wide that it's hard to hit an enemy a couple of yards away.
* WhatHappenedToTheMouse: You know that guy, Viktor Sudek, that you dropped the demolition charge in the lap of in the opening chapter? He's Nadia's father. The script totally forgets to make anything out of this or even mention it.
