Vault 69 feels like somebody took a Fallout parody, spilled a full Pornhub search history on it, and then said “yeah ok, this is the plot now”. You play as the only useful dick in an underground vault that ran out of common sense and condoms at the same time. The Overseer basically pats you on the shoulder and says “go breed, champ”, while the whole place is full of desperate, half-broken, half-horny people that somehow still find time to argue about rations and power supply. It’s not subtle. It’s not trying to be smart. It just throws you into a post-apoc mess where your cock is both resource and weapon. You walk around the vault, talk to girls who are clearly one bad day from snapping, and every choice is like a weird mix of dating sim and HR management, if HR was about who gets to swallow and who only gets it up the ass.

What I liked is that the game doesn’t pretend sex is soft or romantic. It’s rough, dirty, and sometimes a little fucked up in the head. You’ve got big-titted slaves, “volunteers” that are clearly not okay, raiders topside who think “negotiation” means forcing the protagonist to prove his value by breaking in new captives. One scene had me trying a pickup line like “Let’s save humanity together” and the girl actually laughed at me before forcing me to go down on her as “practice” for future breeding candidates. Another time I tried a more aggressive line, something like “Bend over the desk, I’m tired of talking”, and she just locked the door and went full dom on me instead, using my face on the chair and calling it “evaluation”. The game loves flipping your expectations like that. Sometimes your cheesy line works and opens a new hardcore scene, sometimes it gets you punched, sometimes it triggers a weird management event about population stress where you’re suddenly filling forms after filling holes. And yeah, those stupid little stat prompts that pop up on screen, they feel like Excel sheet made horny. I hated it. I also kind of liked it. I don’t know.

Outside the vault it gets nastier and funnier at the same time. You meet wasteland chicks who are way more dangerous than the gun they’re holding, and somehow the dialogue still makes room for cringe pickup attempts. Had a moment where I tried to be smooth with a raider girl, something like “You look like trouble, I like trouble”, and she just put a boot on my chest and told me I’ll “earn the pussy” by bringing her slaves to trade. Next thing I know, I’m back in the vault doing this awkward loop of cold resource management and hot, brutal sex, trying to decide who gets treated like a person and who gets used like equipment. The violence can be a bit much sometimes, honestly, but the world is so broken it weirdly fits. I wish there were more soft scenes where characters just fuck for fun, not duty, but this setting is not really about cozy cuddling anyway. It’s about mouths full, asses sore, power plays everywhere, and you stuck in the middle pretending your shitty pickup lines are actually saving civilization. At least when I alt-tabbed to check Discord after a particularly harsh anal scene, my brain needed a second to remember that in real life, people don’t usually ask “What’s your breeding quota today?” so I guess the immersion works a little too well.

Celia’s day is already trash before the truck hits her. Classic isekai setup, but here it feels more like being yeeted out of a Discord call after saying the wrong thing in NSFW chat. She wakes up in this ridiculous fantasy world, still a lazy NEET at heart, except now there’s a smug dragon spirit living in her head and her body got “patched” in the weirdest way possible. One minute flat-chested hoodie goblin, next minute she’s futa with a magical cock that reacts way too much to teasing, fear, and honestly just light breeze. The game has fun with that. Sometimes a monster girl leans a bit too close, the screen shakes, and Celia’s “new equipment” twitches in the art like it has its own opinion. You don’t need a tutorial to understand where this is going. Dialog is like late night horny shitposting: awkward, self aware, dumb jokes about game dev and life, then suddenly someone is on their knees giving her a sloppy blowjob while the dragon spirit makes commentary like a pervy Twitch chat in her head.

What surprised me is how many scenes just spiral. You start with this goofy “pickup line” minigame, right, where you choose lines that range from smooth to absolute trainwreck. You try something semi romantic and end up with the busty milf monster girl pressing Celia’s dick between her huge tits and going to town, drool everywhere, her tongue poking out in that stupid ahegao way that would get you banned from Twitch in half a second. Pick the most cursed line and the same girl laughs, shoves Celia onto a bed, and suddenly it flips into a rough anal scene where Celia’s the one getting pinned while still jerking herself off, moaning like she’s going to break her own voice. There’s a lot of that weird double layering, where she’s fucking and getting fucked at the same time, creampies both ways, cum dripping in places the dragon spirit really doesn’t need to comment on, but does anyway. The AI CG looks like the dev fed a bot too much hentai and then just clicked “yeah, that’s good enough” and honestly it fits the tone. Monster girls with stupidly big tits, weird little details like claws around her shaft during a handjob, or a footjob scene where the girl’s toes are painted some tacky pink that somehow makes it way hotter. Sometimes the faces look a bit off, but when the futa protagonist is balls deep in some demon girl’s pussy and her belly bulges just a bit after the creampie, you’re not exactly opening Photoshop to complain. It plays smooth on mobile, too, perfect for that “just one more scene” loop where one minute you’re laughing at a meme about truck-kun and the next you’re watching Celia deepthroat a toy to “train” before she tries to swallow a monster girl’s cock in a harem scene that gets way out of hand in the best possible way.

Nothing here is subtle. You start as this horny guy dropped into a very familiar “busted” setup that anyone who’s seen the Y3DF comic will clock in a second, and the game just leans into that with zero shame. Big curves, big attitude, big mistakes. The whole thing is built around catching glimpses you’re not supposed to see, pushing your luck a bit more each click, then pretending you “didn’t mean it” while the camera angle says yeah, you definitely meant it. It feels like peeking through a half‑closed door and then, slowly, that door stops being so closed. There’s this constant teasing rhythm: you get a shot of her walking away, ass swaying like it has its own schedule, a little jiggle animation that plays one second too long, and suddenly you’ve forgotten what choice you were even supposed to make. I liked that a lot. I also kind of hated it because I kept backing up to replay the same scene. The game is short, but it somehow still makes you loop little micro-moments like an addict.

What really got me is how often the game points your eyes exactly where you shouldn’t be looking. You’re “helping” her in the kitchen? Screen is framed so those huge tits are right at the edge of the image, bouncing just enough, like the dev sat there in Blender or whatever and asked “ok, how far can I push this before it looks stupid?” and then pushed it further anyway. There’s groping that starts almost by accident, then the camera pauses, like it’s asking you, are you going to move that hand away or are you going to be the asshole you know you are. Spoiler: you stay the asshole. The voyeur parts hit harder than I expected; watching her in bed from the doorway, seeing those slow animated thrusts when she’s “busy” with someone else, and your character just stands there listening to wet mouth sounds and muffled moans, that was kind of brutal in a good way. NTR fans will grin, others will stare at the screen like “why the fuck am I horny and mad at the same time.” I had one scene where she’s on her knees with her lips wrapped around somebody who very obviously isn’t you, and the game just lets that animation loop while you pick between weak, jealous options that don’t actually fix anything. It’s nasty, in that porn‑you‑don’t‑admit‑you‑like way. The titfuck scene is way softer by comparison, almost affectionate, with her sliding those massive boobs around you like she’s trying to “make things better” in the worst possible way. Still, I kept wishing there was one route where she didn’t cheat, even though I know that would wreck the whole point, so that’s never happening.

Denji’s trapped again, but this time it’s not about blood or blades. It’s a damn maze of moans and bad decisions. The walls hum like they’re watching, the air sticky with that half-sinful, half-desperate energy only Chainsaw Man chaos could pull off. Kobeni trembles like always - except now she’s trembling for different reasons. You can almost taste her panic when your hand slides under her shirt, that mix of fear and wanting that shouldn’t feel this hot but somehow does. Himeno’s smirk cuts through the tension like a knife dipped in smoke; she knows exactly what you’re thinking before you even move. She plays dirty, whispering things that make you forget which way is out, makes you think maybe getting lost forever wouldn’t be so bad.

The game doesn’t rush. It teases. One second you’re grinding through dialogue choices that seem stupidly simple, and then suddenly it hits you - this isn’t about saving anyone, it’s about corrupting them just enough to see who breaks first. Internal view scenes hit hard, no filter, no mercy. The sound design’s nasty in a good way - sticky breaths, little gasps, wet slaps echoing through the infinite corridor like applause. There’s humor too, weirdly enough. Power barges in at the worst possible moment, yells something ridiculous, and you still can’t help but laugh even as the screen flashes another throbbing close-up. It’s gross and sexy and kinda tragic all at once.

And yeah, the endings. Plural. You’ll probably screw up the first one, because some options look harmless until you realize they change everything. There’s a scene where Denji just stares at his own hands, covered in… well, you know, and it lingers longer than comfortable. That’s the thing - nothing here feels safe, even the pleasure. It’s messy, horny, strangely tender in places where it shouldn’t be. Like the game itself is laughing at you for getting turned on by its cruelty. And maybe it’s right.
