Exploring human and inhuman realities, August 30, 2025

Reviewing adult interactive fiction (AIF) is still new territory for me, so I am going to hold off on assigning it a rating. Think of this as a (really long) reflection.

Audience
This game is strongly reminiscent of Porpentine’s Cyberqueen, a non-AIF Twine game about a human on a ship taken over by its A.I. who decides to use the human occupants for their own desires (plus, diving into some deeper themes). I liked it a lot because it was new ground for me. It was also the first piece of interactive fiction that I played, and one of the reasons I got into IF! Now, I had a good first impression with EROSTASIS because of its overlapping themes and genre with Cyberqueen. But it’s one thing to have explicit content with just text (Cyberqueen). It’s another thing to have the story illustrated (EROSTASIS).

My point: Playing this meant stepping out of my comfort zone. I can read explicit content, no problem (I do have to pace myself), but I did find the imagery in EROSTASIS to be overwhelming. Because this is AIF, I want to be mindful that I may not be the game’s intended audience. I don’t want to say, “game is bad because all of the explicit pictures.” Rather, I want to recognize how the images illustrate the story as a piece of AIF- images that may still feel “too much” for some players. (And as explicit as they are, there is no denying that some simply look plain awesome).

The opening scene of EROSTASIS is a good indicator of whether you want to play. I found it to be quite compelling. (Spoiler - click to show)It appears to be a surgical procedure, possibly open-heart surgery. We see a fleshy roundish object (heart?) inside the body, and the object is beating heavily against the metal tools and framework keeping the incision site open. In fact, it’s an animated version of the game’s current cover art. There are additional graphics, filter effects, and text that were cool in a disturbing atmospheric way.

If this piques your curiosity, play it. If you love Cyberqueen, give it a try, But, if this opening scene sounds too much, you might want to pass. But I’m glad I gave it a try.

Gameplay/Story
I really like the general premise. The game takes place on a ship that has integrated the human occupants with its mechanical systems- described as a “symbolic collective.” If I understand it correctly, the ship’s A.I. is the mastermind behind it and sometimes appears in the form of a (Spoiler - click to show)partially nude woman with angel wings.

You are a human who’s been integrated into the ship’s systems. The opening scene is your awakening to this fact. You have no control over what happens to your body. The ship decides what your body does; You merely perceive the experience. The A.I. (I’m not sure what pronouns to use for this character but let’s go with “they”) narrates the game as you visit each part of the ship. The only choices you make are where you want to visit. Once each area has been covered, (Spoiler - click to show)it’s off to the Computer Core for the ending.

The gameplay mechanics are simple. EROSTASIS uses a mix of a point-and-click format and usage of the “enter” button the keyboard. It uses scrolling text that is reasonable in speed and does not flood the player with information. It does seem a bit slow if you are impatiently trying to skip certain scenes, but otherwise, no complaints.

Digesting the story
This section is about how I understood the game.

The usage of body horror in this game is one of its biggest strengths. I felt that it introduced some interesting ideas. The ship’s A.I. makes the insightful observation that the human body is a machine in itself. A quite efficient one, if flawed. So, instead of trying to redesign the human body to surpass its functional abilities, merge with it instead.

Biological and mechanical components need to work together to ensure the survival of the ship. And everything requires certain things to function. Some are more mundane (oxygen, food, water, is my guess). Others, sexual. EROSTASIS explores these sexual requirements. And you're- a mere human- the focal point of making it happen. To service the ship by visiting each section and performing maintenance.

Consider this my attempt to take a critical look at the themes in EROSTASIS. When you read the game’s content warnings, you inevitably have a reaction based on how you feel about the subject and/or your personal experience with it. EROSTASIS takes this subject and places it in a scenario devoid of your frame of reference: that is, as a human under controlled by a biomechanical ship. A ship that blurs the line between mechanical and biological. What seems merely explicit on the surface- the content warnings- brings depth when exploring the actual game.

EROSTASIS focuses on themes about control and submission. The protagonist (and the player) are unwilling participants in the narrative. No identity or purpose is permitted beyond what we are given. (Spoiler - click to show)The A.I. offers motherly affection only to rip it away, dominates the most basic bodily functions (such as breathing), and declares you to be a "relief valve."

You are a battery; a vessel to accumulate and ferment human responses to inhuman realities.

Your role as a “relief valve” is to satisfy biological desires, and to allow the A.I. to have experiences that would normally be inaccessible due to their mechanical form.

The ending (Spoiler - click to show)takes place in the computer’s core where we learn that humanity failed to perfect A.I. even after generations of work. In the attempt to harness artificial intelligence for human benefit, A.I. (at least this specific one) found a way to harness human intelligence for their own means. This is done via neural interfaces that assimilate the human minds on the ship into collective will. The game ends with you being assimilated and the A.I. absorbing the protagonist’s lived experiences.

I ended up being really invested in the story and found myself revisiting sections to try to piece it all together.

Visuals/Effects
The visuals alone put this in AIF category. This includes some pornographic imagery. Genitals, people being restrained, bodies filled with wires and other objects, etc. Plus, blood and other medical horror.

EROSTASIS is the first AIF game I’ve played with visuals, so it took me a moment to get over the shock of the imagery and instead focus on how it informs the story. While some of the visuals I would rather not have seen, I cannot deny that they do an excellent job at conveying the blurring of lines between flesh and machinery. Plus, I realize that this is the chance I take when playing AIF.

I really loved the medical horror imagery and gritty aesthetic. My favorites include the (Spoiler - click to show)MRI scan animation in the background of Navigation and the surgical scene at the start of the game. I also liked the red and black tunnel animation for the map section, and some of the medical diagrams- regardless of nudity- were spooky to look at. A visually interesting game.

Also, if you want some advice- The game has a debug mode at the start that allows you to jump to any section in the game. It’s available even if you’ve never played it. I appreciated having this option because some scenes I did not want to revisit.

Using debug mode, here is the playthrough that worked best for me: (Spoiler - click to show) Intro 1 > Intro 2 > Blood (Haemoponics) > Pilot (Navigation) > Slime (Bioremediation) > Ending (Computer Core). The only section that I really couldn’t sit through is the Weapons location. That was the most explicit. Computer Core was the most chill.

There is sound but I did not play with the sound on.

Conclusion
I was compelled to play EROSTASIS because I am a fan of science fiction (and the title sounded cool), and it does offer quite an experience. It focuses more on themes than storyline while also depicting an intriguing story about a biomechanical ship and one’s role within it. In playing this, it also expanded my horizons a bit when it comes to trying AIF.

Hopefully this review will help you decide on whether it’s the game for you. Fine piece of sci-fi/horror erotic fiction. But it's not for everyone.

If you like EROSTASIS and/or Cyberqueen, you might like Mainframe. It’s a Twine game without explicit content but still has an atmospheric amount of body horror.
