''Dreamkiller'' is a dark fantasy-themed FirstPersonShooter developed by Mindware Studios and published by Aspyr in 2009 for Microsoft Windows and Xbox 360.

The gameplay format is more or less inspired by ''VideoGame/{{Painkiller}}'', but set entirely in DreamLand, featuring surreal, eerie atmospheres that compliments the game's psychological themes. That, besides kicking ass with assorted firearms.

As a child, Alice was plagued by recurring nightmares where she's constantly hunted by demons, until she eventually decides to fight back and overcome her fears, which somehow unlocks her latent psychic powers she had in her. Destroying the demons in her dreams and keeping them sealed within the darkest corners of her mind, Alice's life would change forever when she decide her ability is both [[BlessedWithSuck a gift and a curse]].

Growing up, Alice works as a psychologist with powerful mental abilities that allows her to enter the minds of patients and battle their inner demons, where she can purge their phobias for them. But late into her investigation, Alice's childhood fears started re-manifesting, and she will have to confront a dark, repressed memory she assumed was long gone...

Players assume the role of Alice, navigating through multiple levels consisting of surreal and twisted dreamscapes filled with nightmarish creatures. Alongside traditional first-person shooter mechanics, ''Dreamkiller'' also features unique dream-themed elements, such as the ability to enter and explore the minds of different characters each with their own distinct level design and enemies, as well as granting Alice special psychic powers like telekinesis and mind control besides the assorted variety of firearms seen in FPS games.

----
!! After all these years, there's only one thing that makes me happy... sleep ''without'' dreams.
* AliceAllusion: This horror-themed game has a protagonist named Alice, who spends the entire game travelling between nightmares to battle the forces of evil. Let that sink in for a second.
* ArmCannon: If a humanoid-based enemy has a ranged attack, chances are it's an organic cannon / gatling gun mounted on it's arm.
* AntagonistTitle: Yeah, all those gigantic monsters and creatures serving as bosses Alice battles at the end of each stage? They're the titular "Dreamkillers", demons residing in the dream world who wants to consume the minds of anyone who drifted into their realm. Alice in contrast is the "Dream Savior", and she confronts [[spoiler:the lead Dreamkiller, the Dream Devourer, at the end]].
* BedlamHouse: The nightmare stage in "Paradise Asylum", where all it's inmates are deformed into monstrosities and attacks Alice without provocation.
* BodyHorror: Most of the humanoid enemies, where their bodies are either a deformed mess of limbs, their arms fused into their midsections, grafted with assorted machinery, or tentacles emerging from various orifices, you name it.
* BossRush: The last stage sees Alice fighting all the previous KingMook bosses, as well as enemies from past nightmares which weren't even hers, to reach [[spoiler:the Dream Devourer]].
* CameraAbuse: Whenever Alice gets hurt, the screen gets splattered with plenty of red. It does make sense since the whole game is in first-person.
* CyberCyclops:
** The boss of "Skyscraper" is a humanoid robot with a single red eye it use to fire EyeBeams on Alice. It's body is based on the stage's recurring enemies, but none of the mook have his abilities.
** The final level where [[spoiler:Alice enters her ''own'' mind]] have smaller one-eyed robots as enemies.
* DeliberatelyMonochrome: When Alice enters Berserk mode, the screen goes greyscale, while onscreen enemies glows red. Enemies killed while Berserk mode is active turns grey like the background.
* DisintegratorRay: Another weapon Alice could use, which fires a straight, high-temperature, orang eenergy bolt. Mooks killed by this weapon tends to get ReducedToDust.
* DreamLand: Every single level is set in a patient's nightmare, where Alice uses her powers to purge whatever existing phobia for her clients.
* DreamWalker: Alice is a heroic example, entering the dreams of people to eliminate their nightmares. [[spoiler:The Dream Devourer on the other hand is a hostile one]].
* DyingCurse: [[spoiler:Upon being killed, thee Dream Devourer's last words were to taunt Alice that there are more Dreamkillers out there, ready to take his place, and they will return to haunt Alice the next time she sleeps. Alice's answer?]]
--> '''[[spoiler:Dream Devourer]]''': You will never be free! Never!\\
'''Alice''': Huh, you know something? You've got a really big mouth. Good night, [[spoiler:Devourer]], and pleasant drams.\\
'''[[spoiler:Dream Devourer]]''': [''dies'']

* FlyingFace: [[spoiler:The Dream Devourer's final form is a gigantic, building-sized floating head]].
* FreezeRay: Alice can obtain a Liquid Nitrogen-powered gun that allows her to perform a KillItWithIce on enemies.
* GatlingGood: One of the earlier, better pickups Alice can use is a minigun, very useful for mowing down hordes of mooks.
* GiantSpider: The first level, being set in nightmares of a client with Arachnophobia, predictably features ''huge'' spiders as enemies. There are even SpiderPeople later on as enemies.
* HiddenVillain: [[spoiler:The Dream Devourer who controls all the Dreamkillers doesn't appear until the final stages when Alice re-confront sher suppressed childhood phobias]].
* ImNotAfraidOfYou: In the prologue, Alice (as a child) decides to fight back against the monsters in her nightmares, and she wins. It then she realize she has special powers to help others with, changing her life forever.

* LightningGun: Alice obtains a rather powerful one in later levels that allows her to electrocute enemies. Hold on the firing button an mooks even displays XRaySparks.
* {{Macrozone}}: Part of "Toy Theatre" sees Alice shrunken to doll-sized. It's not too obvious at first, but then Alice looks up when passing one of the walls and realize the "curtains" are used receipts.
* PlayingWithFire:
** Alice can use her telekinetic powers to incinerate mooks, if the player doesn't feel like maiming or flinging.
** The two [[ElementalEmbodiment Fire Elemental]] DualBoss, expectedly. One of them uses normal orange fire, while the other uses [[TechnicolorFire purple flames]].
* PsychicPowers: In the dream realm, Alice can use her mental powers to crush, maim or [[PlayingWithFire incinerate]] enemies if unarmed. Unfortunately she can only focus her energies on one opponent at a time - her psychic powers are best used for facing small amount of enemies, while groups of mooks can best be shot to bits.

* SharedDream: Alice can enter her client's dreams and share their nightmares.
* ShowWithinAShow: One nightmare leads Alice into an abandoned theatre somewhere in the distant future containing several fictional movies, most which are based on real, existing ones, complete with ParodyNames - ''Hovno'' (an ''Film/{{Alien}}'' parody where the iconic Alien Egg poster is replaced by a glowing green toilet), [[Film/TheMummy1932 The Mammy]], [[Film/CreatureFromTheBlackLagoon The Monitor from the Black Lagoon]] (the creature's head is replaced by a computer screen for good measure), a ''FIlm/{{Jaws}}'' spoof with a giant nrubber ducky instead of the shark), [[Film/KingKong Ping Pong]] (a gigantic paddle attacking New York)... and ''Film/SawI'' '''''[[RidiculousFutureSequelisation 29]]'''''.

--> '''Medic''': She's awake!... You've given us a fright, Miss. We thought you'd never come around. Are you alright?\\
'''Alice''': I have some strange dreams, but I'm fine now.\\
'''Medic''': What were you dreaming about?\\
'''Alice''': [''remembers the last stage, and the horrifying [[spoiler:Dream Devourer]]''] You don't really want to know, trust me...
* YourMindMakesItReal: If Alice dies in the dream world, she dies in the real one as well.
