Others - Completed - Parasite In City [v1.03] [Pixel Factory]

One of this site's classics, still a great 2D sidescroller hentai game in 2025.
However, there are some things that didn't age well:

The game does not let you change the window resolution and it is pretty small.
There are only 7 enemy types (three zombie types, one flying insect, two facehugger monsters and the final boss). The game is short, you can beat it in less than an hour if you don't lose too often.
The difficulty is super high. You can only take 12 hits until you get a bad ending. There are very few checkpoints and you can't save, only restart from a checkpoint. Your weapon has limited ammo and kicks are weak, reloading takes a long time. New ammo and health potions are hard to come by. Leaving one level and entering another does not refresh your ammo or HP. Farming enemies does nothing and there are no shortcuts. Movement feels heavy, jumping is awkward. There are some traps that effectively just equal a game over no matter how much HP or ammo you have left. Also, if she gets too horny while too many enemies are on top of her, you get softlocked and have to restart the level.
I highly recommend playing on easy mode.

Now the bad part out of the way, here all the good things. Not necessarily unique, but you can see why they became standard for this type of game.
The female protagonist is still one of the hottest hentai game protagonists. The voice acted moans are greaet.
The struggle mechanic is very well implemented. Breaking free when an enemy catches her becomes harder the hornier she gets and when further enemies pass by, they'll join in and it becomes a threesome - the animations transition into each other. Losing the struggle does not come with negative consequences, except for one enemy that will impregnate her and cause her to give birth to more enemies, which can then impregnate her again. Some enemies have different scenes depending on the direction from which they catch her or if she was on the ground.
You can stay on the ground to see more sex scenes, though it causes HP loss sometimes.
There is a gallery mode to rewatch bad ending CGs and an "omake" that lets you watch all the animated gameplay hentai scenes - except for the impregnation part, for which you have to go into gameplay.
Luckily beating the game unlocks the "infinity health" and "infinity bullet" cheats, which is really the highlight of the game, since it lets you go through all the sex scenes in gameplay with no downside.
However, it does get old fast once you've seen everything.

For pixel-based porn games, this one is probably my all-time top. The variety of interactions, FF, partial vore, the pacing, resource management, how smooth the controls are... this game sits at the top of lewd 2D side-scrollers.

I admit, I'm one of those who wasn't familiar with this game before and didn't realize its classic status. Surprisingly, despite her age (over 10 years old!), she looks no worse than modern representatives of the genre.
Which is impressive:
✔ Stunning pixel art – from characters to backgrounds and decorations.
✔ Excellent sound palette: from the rustle of footsteps on different surfaces to the emotional cries of the heroine in Japanese ("Yamate!" – when she pushes enemies away).
✔ Addictive gameplay – simple but addictive. Despite the seeming simplicity, the game is addictive.
✔ Rich content based on the classic mechanics of "heroine's defeat" for the genre. The enemies are diverse: from zombies of different body types to monsters and insects. Combinations of enemies are especially successfully implemented with their large number in scenes of sex with the heroine.
The presence of a plot is schematic, but atmospheric. He explains why the heroine found herself in this dangerous situation, which gives the game an additional charm.
What disappointed:
✖ No background music – the atmosphere could have been deeper with a suitable soundtrack.
✖ Poor navigation – on the first level, I wandered in circles for a long time until I accidentally found a way out. Minimal hints (arrows, path illumination) would not hurt.
✖ Technical flaws – the heroine periodically fell through the textures.
Result:
This is a great beta version, which even after a decade remains worthy of attention. It's a pity that the developer didn't bring the project to perfection – with bug fixes and the addition of music, the game could have become even better.
Rating: 4/5
I recommend it to connoisseurs of pixel art and nostalgic platformers. If you close your eyes to the roughness, you will have a lot of fun!

Clasic H-game, started an era of hentai gaming inspired so many other games with similar gameplay.

The gameplay is fun movement is smooth and doesnt feel clunky at all, scenes are really well made and theres a good variation.

Hoping the creator is alive and well and we hear from him someday

Kinky game, good mechanics, all around lots of fun. Also the game is actually complete which seems somewhat rare for these style of games. Definitely recommend for anyone into monster / creature content

Looks promissing but the comabt system and controlls are kinda bad placed. Its really hard to get a hang og the controlls. h

Oh yeah, this ones a classic. Over a decade old and it holds up extremely well.

The art is fantastic, doesn't lean too hard into a generic anime aesthetic whilst looking sexy as hell, it's rare to find CGs and pixel art that looks as crisp as in here. A hot busty blonde as the centerpiece with monsters that look great and are styled well enough to sell that the city has gone down with something really bad.

Simple but serviceable gameplay. But one touch I really like is how the cricket enemies can impregnate you and you can eventually give birth to more crickets.
This is definitely a Me problem, but I kinda wished the game played into its title a bit more. There's a sickness going down in the city, so have the enemies influence our character more, so make maybe make her skin blue? Give her different animations showing a change in enthusiasm? Show her with more monstrous traits as the game goes on? But as it stands, we only get a vague mention in the ending how her body has started changing, so alas.

The only major problem I have keeping this from 5 stars is STAGE 3. The main crux of the level is that it's an escape sequence where infected continue to spawn in from the left and you have to run to safety. It's a fine concept, but what's really killing it for me is the spawners who keep making bugs indefinitely. The bugs themselves were already tricky targets to hit, but for these progress halting bugs to be spawned ad infinitum while you're on a time crunch to hop from platform to platform is way too obnoxious to mash out of everytime one lands on you.

Overall, it's still a fun time, give this one a couple of hours to at least unlock the gallery by beating the game.

The one, the only, the OG and the GOAT. I'm just posting a review just to know I did. Everyone knows its amazing. Everyone who's played the game knows its the definition of "Classic". You'll see hundreds of h-games taking cues from this one even to this day. A simple side-scroller with a shoot and scoot gameplay & plenty of A+ h-scenes to see in-between.

actually, for the 10 y.o. game - surprisingly good
sadly - it lacks some content and death scenes is just terrible as its a one cycled gif even without ending, it just goes on and on, but omake's are great and I really liked the idea with zombie silhouettes banging and sometimes interrupting to chase the player on second stage

Pretty fun game, i remeber watching the full galleries videos when i was a kid xdd, The animations are the best pixel art i ever seen and the gameplay is fun. I heard dev retired i hope some day he do another game. (sorry for mi bad english) 9,5

As a product of it's time, this might've been revolutionary. I however didn't play it then. I DID play it recently though, and I can say it just isn't a great erotic game.

As a sidescroller, it's very short and somewhat unbalanced. It is however a pretty capable implementation, and if it were ballooned into a full game with more engaging/forgiving level design, it could be something special. However what's here serves essentially as a foundation for something that never really was delivered.

As for the erotic content, what's there is good, but for my money the game isn't going to really give you the chance to take advantage of it. The tense and engaging gameplay means that you're more concerned about that than sex, and wanting to get back to it asap whenever a scene might start. Imagine that feeling of impatience you get when playing a platformer and waiting 15 seconds for it to reload the level that you just died on. Now make that 15 seconds the sex scene. Basically by making the game challenging and inserting sex in the midst of that, you're asking the brain to code switch, and your hands to switch, pretty abruptly.

Put this all together and I feel like this is ultimately just a tech demo that's as outdated as any other decade old tech demo.

no explanation needed, this game is the classic H-game.

The tags, the gameplay and sex scenes are just way beyond my expectations considering how old this game is and how the graphic aren't even that neat. But this is hands down one of the most classic games and if you're fan of H-games, you must play this. It's very challenging as well. Best platforming game of its kind.

Despite it's popularity, not a big fan. Very little content (3 stages) and the content within the stages is minimal at best. For example, Stage 1 has you running through the same sewer background the entire stage. Combat and gameplay feels very slow and leaves a lot to be desired. Controls aren't the best. Art is great though.

Great game.
The gameplay as a 2d sidescroller is simple but efficient.
There is a lot of different ennemies which trigger various H scenes.
The pixel art and animation are really great.
Highly recommended

4/5 Timeless Classic
This game is quite old by now, but still holds pretty well!
Pretty simple, a bit challengind (due to how fragile the mc is) and great H scenes.
The only thing that doesn't make this a 5/5 is the difficulty and roughness of the gameplay.

one the best if not the best sidescroller porn game. The animations are top notch and the gameplay is fun. I heard dev retired, really a pity. I would have loved more content or parasite in city 2. Great Art and animations. 5 stars.

If you do not rate this game with 5 stars you do not belong on this forum, period. The game is a masterpiece.

Combat is challenging and makes you conserve ammo and use melee, making for some interesting gameplay. The animations are all moster rape obviously, though you better clear the game first to unlock the gallery, it's worth it.

Best hentai game ever, very sexy, very simple, hot zombies, hot blondie, has very hot fuck scenes despite being only pixel art and oh boy don't even get me started with the game over scenes, those are the cherry on the cake.

This review is adressed towards version 1.03, which is the final version posted on this site.

After playing a WIP game that is pretty much following the path of this game, a side scroller zombie rape game, I got the itch to play the original game which gave birth to this type of side-scroller, Parasite in City.

And I have to say, even after all of this years, it holds up quite well.. let me tell you why

.- Art is quite beautiful, animations are pretty good as well. Very nicely done pixel art overall, enemies are nicely done as well. Playable character is quite attractive herself, no complaints whatsoever in this regard, game over CG's are super nice and what's better, they're animated too. It's quite clear how passionate the developer of this game was in regards to this, only complaint.. or, let's just say, downside to this is that the sex scenes tend to be quite short

.- Sound effects are rather nice as well, the only one I'm not all that fond of is the sort of squishy sound for when she's being fucked, it's a bit off putting.. and in the gallery (or well, rather called, omake.. I never exactly understood why they're separated. Omake is pretty much for the sex animations, while the gallery focuses solely on the game-over CG's) it can get a little glitchy as well which makes it a bit bothersome.. but overall pretty decent SFX, especially the gun ones.

.- Story is.. a bit lackluster to be honest, you pretty much wake up in your apartment one day only to find that suddenly there's zombies everywhere and you're trying to escape.. the ending was a bit better in terms of lore, but to be honest.. there isn't really much more than that, it is very simple.

.- Lastly, here comes the part where I had the most trouble.. the balancing of this game. I have quite honestly forgotten how absolutely unforgiving this game can be, especially in the last stage. Stage 2 is the start of the unforgiveness but it's tolerable as you can block enemies with the boxes that are scattered around the map and they can never chase you down until the final part of Stage 2 where a horde of enemies will come after you.. Stage 3, in comparison.. is a fucking nightmare

Not only do the enemies are able to.. clumsily, yet still capable of, vaulting over the boxes to put pressure over you, but there's also the fact that.. depending on which difficulty (I started on normal myself then had to switch to easy because my god), the enemies will take so many bullets to finally die, to be specific.. six for the female and male zombie, unless you're shooting them with the pistol, in which case it's three (not the fat male one, the lanky one, the fat male one takes even more bullets to kill). Pair this to the fact that, as you progress, these face huggers will make your life a living nightmare.. Yes, you can kill them relatively easy, but when you get to this worm-face type of enemy, which will NON-STOP SPAM the shit out of them while you're trying to advance forward and kill other enemies that are standing on your way.. it gets really annoying and irritating, borderline rage inducing.

To boot, the female hitbox works a little weirdly and kicks are not the greatest tool against her (when it's more than one).

The only way to give yourself a little room to breathe and be able to do something in these final stages is if you decide to play it on easy.. or unless you're a hardcore player and you want to torture yourself XD.

In conclussion, very good game while at the same time being very unforgiving and sometimes confusing, the first stage mostly where it feels like a maze and you don't exactly have a map to somewhat orientate yourself.

This game is an absolute masterpiece. This is the game that other side-scroller h-games get measured against.

Fantastic gameplay, quite challenging (on Normal difficulty, I didn't try Easy), phenomenal graphics and h-scenes (considering it's pixel art).

One of the few games on this site that is fun to play, enjoyable to watch, and is actually a polished and complete product.

This is a must-play for its genre.
