[[PunBasedTitle Psi-Ops]][[note]]Another name for psychological warfare[[/note]] is a ThirdPersonShooter designed by Creator/BrianEddy for the UsefulNotes/{{PS2}}, UsefulNotes/XBox and PC that incorporates PsychicPowers into combat and puzzle solving. The game centers around Nick Scryer, a powerful psychic in the employ of the government who has been [[LaserGuidedAmnesia stripped of his memories]] and [[FakeMemories given a new identity]] in order to infiltrate [[NebulousEvilOrganization "The Movement"]], a terrorist organization led by powerful psychics who are defectors from the government. He is aided by Sara, a [[{{Telepathy}} Telepath]] who is also undercover.

As the game progresses the mental blocks inhibiting his powers slowly give way, causing a power to resurface [[PlotTailoredToTheParty just in time for a new puzzle]]. He gains several powers, among them {{Telekinesis}}, MindControl, [[ManaDrain Life Drain]], AstralProjection, [[PlayingWithFire Pyrokinesis]], and AuraVision.

While the shooter aspects are pretty standard, and the story is fairly engaging, where the game ''really'' shines is in the many, many, ''many'' creative and inventive ways players can solve puzzles, kill enemies... and torture them. This game really has possibly the highest VideoGameCrueltyPotential of any [=PS2=] games. Leaving aside the wanton (and fun) [[Literature/AClockworkOrange ultraviolence]], the various psychic powers and puzzle designs lend themselves to very open ended solutions. One area has a pool of electrified water and a locked door needed to cross it. Options are: Use telekinesis to smash an acid container against the door, use telekinesis to [[NotQuiteFlight "surf"]] on top of another object, or Mind Control to make the guard on the other side unlock the door.

The PC version has been released by Midway as ad-supported Freeware, and is available from Fileplanet (Ausgamers also has a mirror download if Fileplanet doesn't work).

Not to be confused with ''VideoGame/SecondSight'', another game with similar premises that came out in the same period.
!!Tropes used in the game include:

* AffablyEvil: Edgar Barrett, especially during Scryer's psionic training flashbacks when a latent power is reawakened.
* AllYourPowersCombined: Nick Scryer's psychic abilities aren't as powerful as those of the specialist members of the QuirkyMiniBossSquad, but he possesses ''all'' psychic powers (except Illusion and telepathy) whereas each Psi Elite member only has one.
* AGodAmI: The General, after using the Monolith to gain superpowers.
** Long before that, Nicholas Wrightson styles himself as the "True God of the Ether."
* ANaziByAnyOtherName: The opening movie shows that the General ripped off quite a bit from ''Triumph Of The Will'' when forming his organization, The Movement.
* AscendToAHigherPlaneOfExistence
* AuraVision: Allows you to see the alertness of guards, Aura Beasts when they're not trying to kill you, FluorescentFootprints, invisible mines, and erased writing on walls. If you kill enemies with it on, you can even see their soul escaping their body!
* AwesomeButImpractical: Pyrokinesis is cool, but poorly implemented. It travels across the ''floor'', so it gets blocked by almost everything. If you have direct line of sight, whatever you're trying to kill should already be dead. The one enemy that can't be TK'd will shake off pyrokinesis at higher difficultly levels before you can use something else to disable him.
* BeatThemAtTheirOwnGame: The Edgar Barrett boss battle, which is a pure telekinesis vs. telekinesis duel. The rest of the boss battles generally favor telekinesis, too, since they're immune to the power they're specialized in.
* BigBadFriend: Edgar Barrett, who was once Nick's trainer but has since switched sides.
* BondOneLiner:
--> '''Sara:''' Mom always did like me better, [[ThisIsForEmphasisBitch bitch]].
* BoringButPractical: Telekinesis will, without question, be your most widely used power. This is followed by Mind Drain for limitless psi power to fuel your telekinesis.
* BossArenaIdiocy: Pyrokineticist Marlena's level has oodles of fire extinguishers... ''self-replenishing'' fire extinguishers. [[JustifiedTrope Justified]], as it's not meant to be an arena, but an important lab and facility which harnesses her powers. Given how unstable she is, they would be foolish not to have all that coolant at the ready.
* BlatantItemPlacement: Psi-vials. Of course, you'll stop paying attention once you get Mind Drain, since it gives you a practically limitless supply of psi energy.
* CliffHanger: For those who really want to know: [[spoiler: The game ends with the General killed via being sucked into a black vortex. Three helicopters enter. Nick shouts out that they aren't there to help, remarks he remembers everything from his past, and proceeds to telekinetically grab one as it prepares to fire.]] Que black screen and the words 'To Be Continued'.
* ConspiracyKitchenSink: UsefulNotes/WorldWarII was fought over the pieces of the artifact the General is assembling. Even the Apollo moon landings had the intent of bringing back more artifacts.
* CoOpMultiplayer: The game features an incredibly unique coop mode, in which one of you controls movement, aiming, and melee, while the other controls shooting and psychic powers.
* CrateExpectations: Crates are everywhere. The first training mission is even based almost entirely around teaching the player to lift them up and throw them.
* DisabilitySuperpower: Jov Leonov was blinded in a childhood accident, but that same accident also gave him frightening powers of MindControl which he uses to great effect. He even sees through the eyes of his controlled subjects.
* DuelingGames: With ''VideoGame/SecondSight'', another third person shooter that combines gunplay with psychic powers. ''Psi Ops'' is a more straightforward shoot-em-up third person shooter with heavy sci-fi and military themes, whereas ''Second Sight'' had more emphasis on adventure and stealth elements and played more like ''VideoGame/{{Hitman}}''.
* EliteMooks: The Level 3 Meat Puppets have 2.5x times as much health as a basic Level 1 Meat Puppet soldier ''and'' special Psi-resistant armor that makes them immune to most of your psi attacks (unless you stun them by setting them on fire or knocking them down with thrown objects first). Of course, in higher difficulty settings their armor has built-in fire suppressants and they have an uncanny knack for dodging your thrown objects.
* EnterSolutionHere
* EqualOpportunityEvil: The General's multinational QuirkyMiniBossSquad of psychic lieutenants.
* EvilTwin: [[spoiler: Amusingly, the Good Twin's original mission was to find and ''save'' her sister, but at the end Good Twin mercilessly guns down Evil Twin (complete with one-liner) after learning she's a douche.]]
* FaceHugger: The Aura Beasts come of nowhere and wrap around Nick's face. Oh, and the only way to see them coming is using the psi draining AuraVision.
* FluorescentFootprints: A feature of Aura Vision.
* ForgottenFallenFriend: Averted. Nick was embedded into a UN squad after his LaserGuidedAmnesia, and one level has the illusionist torment him with the "ghosts" of his dead comrades.
* FunnyBackgroundEvent: Barret's hair changes with each training mission to reflect the year Nick is flashing back to.
* GameplayGuidedAmnesia
* GigglingVillain
* GrievousHarmWithABody: You can always count on mooks as an impromptu weapon to be telekinetically thrown against their fellows. Especially amusing if previously ''[[IncendiaryExponent lit on fire]]'', as fire ''spreads!''
* GuestFighter: [[MortalKombat Scorpion!]]
* GunsAreWorthless: You can carry [[LimitedLoadout two guns at a time]], neither of which will have much ammo to spare, and it usually takes about a clip to kill anything bigger than a normal mook. By comparison, telekinesis can kill several mooks, usually by using the mooks themselves as weapons to kill their friends. The only truly useful weapon is the sniper rifle, for when you need stealth or the enemy is very far away.
* HeKnowsAboutTimedHits
* IncendiaryExponent: Some enemy soldiers burst into flames before attacking you.
** With pyrokinesis, you can also throw {{Fireballs}}.
* IncrediblyLamePun: Marlena is very bad about this. Barrett in the training sections is also quite fond of these.
* InterfaceScrew: Leonov has an attack which inverts your control scheme temporarily.
* InterfaceSpoiler: Averted (at least in the [=PS2=] version) - opening the control layout option in the menu will only reveal the relevant buttons for psi powers Scryer has learnt, not revealing ones he has yet to learn.
* LargeHam: The General, especially in the cutscene leading up to the final battle, when he starts talking with weird facial expressions straight out of a Loony Toons cartoon.
** Actually, a lot of the villains are large hams, particularly in their boss battles.
* MasterOfNone: Nick has the powers of every boss, minus illusions, but is weaker in those areas than they are as a result.
* MeaningfulName: Nick [[http://en.wikipedia.org/wiki/Scrying Scryer]].
* MindOverMatter
* MostDefinitelyNotAVillain: [[spoiler: When EvilTwin poses as Sara, she has a sultry inflection, half lidded eyes, makes off comments, and generally acts "off". Of course, [[IdiotBall Nick trusts her and hands over a piece of the artifact.]]]]
* MugglePower: The General's recruiting schtick, promising psychics rulership over the "inferior" Mundanes as the Psi Elite. Amusingly, he's a Mundane himself, but seeks to correct that with the ancient ArtifactOfDoom.
* MurderByCremation: You can either use [[MindOverMatter telekinesis]] or MindControl to kill enemies in incinerators. There are also a wide variety of means to set them on fire.
* NintendoHard:
** The beginning of the game forces you to ration your psi usage, since you don't get Mind Drain for a while. This forces you to fall back on your crappy guns, since psi-vials are somewhat hard to come by.
** Any part of the game that involves getting past an autoturret can seem this way to the unprepared. The parts at the very end of the game, where you start running through mine-fields and giant, psy-proof mooks with infinite rocket launchers, are Nintendo Hard for EVERYONE. The checkpoint system that the game saves with only exacerbates the problem.
** Further, said mines are invisible without Aura View '''and''' the spaces between them (particularly in the endgame) are almost ''exactly'' as large as a crouching character. You seriously have mere pixels between safe passage and instant death. Thankfully, mooks will set them off, so you can punch larger holes in certain paths by tossing mooks into the mines.
* NotQuiteFlight: [[http://psiops.wikia.com/wiki/TK_surf TK surfing.]] This was actually [[NotTheIntendedUse emergent behavior]]; the programmers initially didn't intend for you to be able to stand on something you were levitating.
* OneWingedAngel: The Illusionist boss turns into a giant monster midway through the battle, although it's really all a giant MindScrew and not actually a physical transformation (although, since YourMindMakesItReal, for gameplay purposes it's more than real enough).
* PeoplePuppets
* PstandardPsychicPstance
* PsychicPowers
* PuzzleBoss: The illusionist forces you to fight two golems, which can't just be shot or beaten to death. Earlier in her level, you also have to fight a bunch of immortal zombie soldiers. Both instances require using your other powers to get around their invincibility.
* QuirkyMiniBossSquad
* RagdollPhysics
* RealSongThemeTune: "[[http://www.youtube.com/watch?v=YiMpY_NJQJE With My Mind]]" by Music/{{Cold}}, written exclusively for the game but still popular with Cold fans.
* SelfMadeOrphan: [[spoiler: Sara's twin sister.]]
* ShockAndAwe: Mind Drain gets the visual trappings of this, with affected mooks twitching convulsively and [[{{Narm}} babbling incoherently]] as they're sucked dry.
* SlaveMooks: All the mooks used by the Movement are this. Mind-wiped, engineered to feel no pain, and controllable en masse by the mind control guy. Leads to a bit of NightmareFuel in the opening, where a rocket is fired into a group of mooks. One does a backflip, lands on his feet missing an arm, and still keeps shooting with his remaining arm.
* {{Telepathy}}
* ThemeTuneCameo
* TrappedInContainment: In the first level there are some gas chambers (well, chambers that have health-damaging gas). Walk in and you get sealed in, usually with a luckless [[EvilMinions science minion]] as a {{mook}} taunts you from outside ''the glass doors''. Amusingly, thrown objects can break the glass, telekinesis can throw objects, and mooks can be thrown just like objects. Alternately, you can skip the escape and tele-toss a mook ''into the gas chamber.''
* VoicesAreMental: When possessed by Wrightson, both Nick and Sara speak with Wrightson's voice.
* VideoGameCrueltyPotential: Practically a mascot for the trope.
* YouHaveOutlivedYourUsefulness: "But... ''true'' power is not meant to be shared!"
* YourHeadASplode: The result of draining a mook of all his psychic energy. One of the more prominent and graphic examples in all of gaming.
** A [[BoomHeadshot headshot]] with a shotgun will produce the same results on a standard {{Mook}}.
** Also occurs when [[RedShirt Sander's]] explosive collar short-circuits: quite horrifically, this leaves a sizeable chunk of his face staring up at Nick.
* YoureInsane: Spoken verbatim by Scryer to Barrett.
