You control the titular Haydee, a very scantily-clad and buxom cyborg woman making her way through a series of progressively difficult and grueling challenges within an Elaborate Underground Base, trying to escape. Along the way, she must contend with various traps, hazards, puzzles, and rogue robots that will mercilessly hunt her down. The game provides no hints, only a handful of supplies that players must carefully manage, and a limited number of opportunities to save their progress as there are no checkpoints. Only your instincts will see your way through Haydee's escape.
A Non-Linear Sequel, Haydee 2, was released in 2020. In it you play as a completely different Haydee trapped in a completely different facility. The game follows her as she tries to escape from an abandoned facility overrun with murderous cyborgs and mutants. While the general premise and gameplay is the same, the sequel removes all the platforming elements and tones down the action of the previous game in favor of pure Survival Horror.
Haydee from the first game, would guest star as a racer in the Mascot Racer H-Game Shady Lewd Kart and she would also be an available skin in League of
Maidens.
Haydee contains examples of the following tropes:
- Ability Required to Proceed: Certain tools are required to access new areas: the screwdriver opens vent grates, the Night-Vision Goggles allow you to see in darkness, the remote and receiver(s) allow you to press buttons from a distance, and the gas mask allows you to breathe in hazardous fog.
- Air-Vent Passageway: Some of the areas have Haydee crawling through air vents and other narrow crawlspaces to travel between sections or rooms.
- All for Nothing: Tragically, all three endings of the game are shaggy dog stories; in the "Escape" ending, Haydee actually fails to escape and finds herself locked in a room with no way out, doomed to eventually starve to death. In the "Control" ending, Haydee kills the rogue unit controlling the facility and takes her place, starting the cycle again. And in the "Deadlock" ending, Haydee uses a proximity mine to kill both herself and the rogue unit, seemingly breaking the cycle... Only for the facility to activate an emergency protocol, effectively rendering Haydee's sacrifice moot as another unit will eventually reach the master room to replace the rogue unit anyway.
- Ambiguously Brown: It's hard to tell if Haydee is just tan, or if her skin-tone is an ethnic thing. Her being part of a mass-manufactured line of identical cyborgs/androids that probably never get exposed to sunlight until/unless they get out of the facility seems to imply the latter, however. Although one of the developers confirmed that Haydee in the first game is indeed tanned.
- Blackout Basement: Most of the Black Zone is pitch-black and requires the night visor to see.
- Boom, Headshot!: Mooks take twice as much damage from headshots. The Slasher bots are also staggered by them, a vital tactic to avoid damage.
- Bottomless Pits: The facility you're trapped in has some, which is instant death if you fall into one.
- Bowdlerise: The game has a censorship option that toggles the visibility of in-game nudity (when applicable for mods) and nude pictures of a woman, who was originally planned to be the original protagonist, can be seen on some items of the game.
- Bulletproof Vest: Downplayed. The Armored Vest reduces damage from Walkers or Slashers, rather than protecting from bullets. (There was going to be a firearm-wielding enemy but that was scrapped.)
- Checkpoint Starvation: There are no checkpoints whatsoever in Haydee, only save points, meaning that dying is permanent and you have to reload from your last save... assuming you made one.
- Colour-Coded for Your Convenience: Each zone has a Color Motif that alludes to its theme. The White Rooms are the Video Game Tutorial, the Green Rooms are platforming-based, the Red Rooms have a lot of pipes, the Yellow Rooms are flooded with Deadly Gas, the Blue Rooms are underwater, and the Black Rooms are pitch black and swarmed with enemies.
- Combat Stilettos: Haydee is wearing white high-heeled stilettos, it doesn't affect her ability to fight nor be athletic and agile.
- Cyber Cyclops: The Slasher enemies only have one glowing eye, while the Walker's downplay this by having two eyes although the second eye is a smaller one below the large red eye.
- Cyborg: Haydee is literally half-robot, half-human, with tight-fitting plastic plates completely armoring her upper-body and absolutely nothing below her waist.
- Deadly Gas: The Yellow Rooms are flooded with this, so the player must have a gas-mask equipped to navigate in it.
- Diegetic Interface: Outside of the hotbar for quick-selecting items and showing the amount of on-hand supplies, there's no in-game HUD to speak of in this game, instead Haydee's health is gauged on the back of her head.note
- Elaborate Underground Base: The game takes place in an underground artificial complex filled with advanced technology.
- Excuse Plot: You're a Robot Girl trying to escape an Elaborate Underground Base, go.
- Expy: Haydee resembles the Combine Assassin, a scrapped Half-Life enemy.
- The Faceless: The robot-half of Haydee gives her a featureless face-mask helmet thing. Being mass-manufactured androids/cyborgs, it's not even clear if Haydee and her peers even have a face under their helmet. Amusingly enough despite the lack of mouth and eyes, she has two wearables she needs to don on her eyes and mouth. Subverted by the second game, which shows Haydee's face.
- Falling Damage: The majority of the damage you'll take in the game is from falling if you're not careful with how high you'll drop from platforms and ledges. You can hang from ledges first to reduce the distance and negate the damage.
- Featureless Protagonist: All Haydee has is a very fanservice-y appearance. No voice, no personality, no backstory, no face.
- Fragile Speedster: The Slasher enemies have the ability to run and can lunge forward to slash at you. However, they can be staggered by headshots (unlike Walkers), deal less damage, and have half as much health.
- Game Mod: The game's Steam Workshop features various mods, from animation tweaks, new maps, and even model/character swaps of Haydee, some of which are very NSFW.
- Girly Run: Haydee's running animation has her running as such, contributing to the bounciness of her breasts, albeit her arms are lowered as she runs.
- Guide Dang It!:
- The game offers little in the way of guidance as to where to go or how to find critical tools needed to proceed. Trial-and-Error Gameplay is very much expected.
- The "Genocide" achievement requires you to kill every robot you encounter. What this precisely means is that you must be able to kill every robot that appears in every room you enter. There is a particular room in the Green Zone where five enemies are trapped behind an impassable gate. If you ever enter this room, the achievement is voided because these robots are unkillable. You also have to be aware of two Slashers in a trap room and set up mines to kill them without being caught in it. Finally, only one of the endings allows the achievement to be completed.
- Hammerspace: Zig-zagged; as the picture above shows, story-wise, Haydee has a backpack to store her tools and supplies. In-game, however, her weapons just materialize in her hand out of thin air when equipped and tools do not appear at all when used.
- Hand Cannon: Both◊ handguns◊ qualify in design, but the Magnum plays the trope straight by doing double the damage of the standard handgun and staggering Slashers on hit instead of only from a headshot.
- Handguns: Haydee's weapon is a trusty black-and-white Glock-esque pistol.note
- Harder Than Hard: The game's Hardcore mode makes enemies deal full damage to Haydee instead of half, medkits only heals half the amount of health compared to Softcore, ammo pick-ups give less bullets for your guns, your inventory capacity is cut down to 9 slots, and your guns now have full recoil and kickback when fired, along with some sway while aiming.
- Heroic Mime: You never hear a peep out of Haydee. Since she's a robot (with no mouth), it's possible it's not entirely her fault.
- Insurmountable Waist-High Fence: Haydee can't jump or climb over/through waist-high railings, despite the gaps being more than large enough for her to fit. Pipes above her jump height likewise are impassible, even though Haydee could climb them easily with a human range of motion.
- Inventory Management Puzzle: Haydee has 12 item slots (9 on Hardcore) and items only stack to a certain degree, so about halfway into the game you have to start managing your inventory to be able to carry necessary tools, weapons, ammo, and have enough free space to pick up supplies. Save points have a storage box for holding all the extra stuff you pick up.
- Irony: Being a faceless Heroic Mime with no known backstory makes Haydee a Flat Character personality-wise. Body-wise, however, she's anything but flat.
- Leotard of Power: Haydee is wearing a thong leotard that hugs her curvaceous body and while providing a good view of her legs.
- Life Meter: Haydee's health bar is built into her, displayed on the back of her head in a similar style to Dead Space.
- Male Gaze:
- The camera focuses on Haydee's assets at every opportunity.
- Humorously enough, this also applies to the other bots too, if you get close to the non-hostile bots, you'll notice that they're staring at Haydee's breasts. This also applies to the sequel.
- Mecha-Mooks: All of the enemies are combat drones.
- Mercy Rewarded: Killing less than 50 bots earns you the "Mercy" achievement.
- Metroidvania: The game is mostly platforming, exploration, and trying to strengthen Haydee and her arsenal.
- Mighty Glacier: The Walker enemies are slow-moving robots, but their club hands pack a bigger punch than the Slasher enemies, they have twice as much HP, and they don't stagger from headshots.
- Minimalism: The game features no dialogue, subtle music for ambiance, rooms that are clean and minimalistic with a few colors being used based on the theme of each zone.
- Ms. Fanservice: Haydee, of course; she's curvaceous almost to the point of parody and the game's camera milks it for all it's worth.
- Multiple Endings: Based on the player's choices, the game can end in three different ways. They can either unsuccessfully escape in the "Escape" ending, go rogue and take control of the facility in the "Master" ending, or have the whole incident restart in the "Backup" ending.
- Mutually Exclusive Power-Ups: The night visor and gas mask cannot be equipped at the same time, even though their design and function wouldn't suggest the two would conflict with each other. This matters little in terms of gameplay, as the Yellow Zone is fairly bright save for a couple spots and there's no need for extended use of the visor.
- Night-Vision Goggles: Haydee can acquire the night visor, which as the name implies is a visor that gives night vision for the dark areas. It has three little green lenses on it.
-
Nintendo Hard: Don't let Haydee's appearance distract you, the game is brutally difficult and puts players through an elaborate facility with murderous robots lurking about, hazardous traps, and complex platforming, all while dealing with inventory management, a limited supply of resources, and a limited number of opportunities to save their progress, with heavy reliance on guides if you don't want to figure everything else yourself. The achievements also reflect how difficult the game is, with only 40 percent of people completing the tutorial, compared to 90 percent dying. The sequel is slightly easier, but it is still a fairly difficult game. - No-Gear Level: The Yellow Zone has a no-gun checkpoint that won't allow you to pass it unless your weapons are left behind. The challenge in this area is controlling which doors are open and which are closed so you can explore without releasing the robots. There's a special chute outside the checkpoint that allows you to place two weapons and retrieve them inside the zone.
- Ominous Fog: Some of the rooms are absolutely choked with fog, sometimes being incredibly thick. This is most apparent on the bridge, the Black Zone, the Green Zone, and the Yellow Zone.
- One-Hit Kill: The Walker enemies can one-shot you if you happen to be playing on Hardcore without the Armored Vest equipped. Similarly, walking directly into an armed mine is instant death regardless of health, armor, or difficulty.
- Pants-Free: Due to only having a leotard, her legs are bare for all to see.
- Permanently Missable Content: If the player rushes into opening the first white keycard door in the tutorial areas of the game, they'll miss the Armored Vest stashed in a few rooms back and can't be unlocked afterwards.
- Protagonist Title: Haydee's name is the title of the game.
- Red Eyes, Take Warning: All of the enemies have glowing red eyes.
- Save Token: The little red diskettes. Hardcore mode, in addition to its other restrictions, also reduces the number of resources you can find, which include said save diskettes. Funnily enough, the diskettes also have the words "Save Me!" written on them.
- Shout-Out: Has quite a few.
- The Diskettes are used in a similar way to the ink ribbons and like from Resident Evil.
- The Life Meter on the back of Haydee's head brings to mind of the RIGs from Dead Space.
- The minimalistic level aesthetics is very reminiscent of Mirror's Edge.
- Supermodel Strut: Haydee's walking animation has her strutting her stuff like a supermodel, seemingly just to invoke Third-Person Seductress.
- Teleporting Keycard Squad: The game will sometimes spawn robots into rooms you've previously cleared if you choose to explore one further ahead. If you have to backtrack after retrieving an item, it's a good bet there will be a robot waiting for you on the return trip.
- Third-Person Seductress: Haydee's breasts are literally bigger than her head and she walks with a Supermodel Strut, seemingly just for the benefit of the player.
- This Way to Certain Death: Different parts of the levels are filled with previous Haydee units that didn't make it, like at the bottom of a chasm, meaning they didn't make a specific jump and fell to their deaths.
- Thong of Shielding: Haydee's suit leaves most of her rear exposed, but has a minimal amount that covers the crack.
- You Kill It, You Bought It: In the "Master" ending, you can kill a copy of yourself in the final room, implied to be running the show, and immediately replace the copy as the new version. The pile of corpses suggest this to be an endless cycle. Alternatively, drop a mine at your feet and end the cycle, which is the "Backup" ending.
The sequel, Haydee 2, provides these tropes below:
- Anti-Frustration Features: In the first game, you could soft-lock the game at multiple points. In this game, outside of running out of ammo, there's no way to soft-lock the game without doing it intentionally.
- Ambiguous Ending: It's left unknown if HD512 even managed to survive the hangar crash or not.
- Contrasting Sequel Setting: The first game took place in a brightly lit, pristine white high-tech facility filled with traps and puzzles that are clearly meant to be a test of some kind and contains almost zero clues as to what it purpose is. This game takes place in a dimly lit office complex that has clearly been abandoned in a hurry with the puzzles being the result of pure happenstance rather than deliberate design and is littered with Story Breadcrumbs.
- Darker and Edgier: The game is noticeably bleaker than the first game in a number of ways. The music compared to the calming and subtle (albeit ominous) music in the first game (excluding the Black/Dark Zone and the credits music), is significantly more depressing and hopeless-sounding. All of the other immobile girls that you find in the facility are actually real people that were kidnapped and turned into sex dolls/cyborg slashers by Evil, Inc. Jurani, and the Creepers that you fight against throughout the game are the employees that got affected from entropy that HD512 caused after she causes an explosion that damages Anchor.
- Offscreen Moment of Awesome: As the revealed in the notes scattered across the game, HD512 made an unsuccessful escape prior to the events of the game, taking down a dozen security bots and causing several explosions before being recaptured.
- Story Breadcrumbs: Unlike the first game, hints about the story are scattered throughout the game.
- Survival Horror: The game dropped all of the platforming and swimming from the first game in favor of something more similar to games like Resident Evil, and Dead Space.
