Parasite Mutant places players in an abandoned city to uncover a conspiracy and fight monsters. Read on to learn everything we know, our review of the demo, and more.
Everything We Know About Parasite Mutant
Parasite Mutant Plot
Psionic agent Nova is assigned a mission on a secluded and abandoned island city. The location is, however, populated by various mutated creatures of unknown origin. Nova’s primary objective involves an investigation into the state of the island. Soon, she encounters evidence of a larger incident that led to the current state of the metropolis. According to the developers, the events that take place during this mission are central to a fundamental change in Nova's fate.
Parasite Mutant Gameplay
Parasite Mutant’s combat centers on what is called Active Time Chains, which merges principles of classic Active Time Battle mechanics found in classic Squaresoft games with segmented timing. In encounters, a gauge fills over time, divided into a number of segments, and players must choose when to act during these intervals. Combat plays out in a hybrid real-time/turn-based style where movement and dodging happen in real time until action gauges are ready, at which point, attacks, item uses, or other commands can be issued.
Outside of combat, gameplay involves exploration and progression systems typical of survival horror RPGs. The demo version includes a tutorial to introduce core mechanics, followed by an initial explorable area that encompasses roughly five to seven percent of the full game’s scope.
Parasite Mutant Release Date
Parasite Mutant does not have a specific launch date yet, but it is scheduled to release sometime in 2026 for PC and PlayStation 5. However, a PC demo launched on Steam on January 7, 2026, which reportedly covers about 5% of the full game's scope.

Parasite Mutant Review (Demo)
Chasing the Ghost of Square Enix Past
We are long overdue for a new Parasite Eve game. I wouldn’t call myself a die-hard scholar of the series, but I’ve played enough to understand why people cling to it. I’ve finished two out of the three entries: the original on the PlayStation 1 and The 3rd Birthday on the PSP. In both cases, I played them mostly out of curiosity. Back in the ’90s, Square Enix (then Squaresoft) tried their hand at survival horror, inspired by the massive success of Resident Evil. The series had an interesting mix of RPG mechanics and horror elements, which made it stand out at the time.
Since The 3rd birthday, though, the franchise essentially vanished. You don’t even hear the name mentioned in official capacities anymore, which has left the fanbase in a spot where they have to hunt for any scrap of news to keep the flame alive. Fortunately, there are studios like indie developer IceSitruuna who are trying to fill that specific void.
Parasite Mutant is marketed as a horror RPG inspired by the adventures of Aya Brea. The developers released a demo recently, and after almost an hour, it’s just… fine. It captures the aesthetic and the basic mechanics well enough, but there is a noticeable gap between the ambition of the project and the actual execution of the demo. It isn't a disaster, but it also hasn't quite proven that it can live up to the cult classic it tries so hard to emulate.
Demo Does a Bad Job of Introducing the Story
The demo puts players in the shoes of Psionic Agent Nova. From what the game tells us, she is sent to an abandoned island city for what should have been a Grade C mission. Her objective sounds simple enough: find and retrieve a "Data Bank." Things seem to go immediately wrong, though, as the demo opens with Nova’s transport having crash-landed on the island. She, then, goes and fights off mutated creatures that look like they belong in a Parasite Eve game. Aside from a few small crumbs of information dropped throughout the mission, this setup is essentially the extent of what we are given regarding the plot.
It is evident that the demo is just the prologue. The entire experience lasts less than an hour, and it leaves a lot of unanswered questions. We see glimpses of monsters that look like Xenomorphs, and the developer’s press releases promise a "hidden conspiracy" and "secrets" that will completely change Nova’s fate. The problem, though, is that none of those stakes are present in the demo. We aren’t given any context regarding the state of the world or exactly why this mission or that "Data Bank" matters in the grand scheme of things.
It is worth noting that this is still just a demo, and with a 2026 release window, the developers likely have a lot of work left to do. However, because the demo is so brief, Nova herself comes across as a very bland protagonist. There isn’t enough reason here to care about her. Usually, when a game tells you that a character’s fate is going to be altered, you need to have some kind of emotional connection to them for that to mean anything. Right now, though, she feels like a generic vessel for the player to control. We don’t know her motivations, her history, or even her personality.
The demo concludes with a revelation regarding Nova that feels premature. Since we lack a foundational understanding of her character, the "reveal" also lacks the intended emotional impact. In fact, we don’t even know what to expect from the story beyond the short overview provided by the developers.
As a vertical slice intended to hook players, it doesn't do a great job of selling the story. You walk away from the hour-long session barely understanding the state of the world. Environmental storytelling can only do so much heavy lifting when the main narrative is this vague.
It’s Hard to Navigate Environments
This is made even more frustrating by how difficult it can be to actually navigate the game’s world. Visually, the environments do look promising. They’ve gone for a very specific aesthetic that features dark and muddy textures, which successfully captures the oppressive feel of the Parasite Eve titles. There is a certain charm to the way it mimics the visual style and vibes of retro PlayStation games, down to even emulating CRT TVs with a filter. The monster designs also look interesting. However, the commitment to this old-school look comes with some drawbacks that affect how the game actually plays.
The biggest issue is that it is often hard to tell what you can actually interact with. Because the color palette is so muted and dark, objects blend right into the backgrounds. There are also various effects added that obscure your view of the environment. These effects add to the atmosphere, but they make it a chore to find interactable objects.
Even with the help of the in-game map, the screen itself remains visually unclear and, if CRT and Retro Aesthetic filters are on, blurry. By the end of the demo, it got to a point where I just started mashing the interact button on my controller while walking along the walls instead of looking for small visual cues.
This is made worse by the use of fixed camera angles. This is clearly a stylistic choice meant to pay homage to the survival horror games of yore, but it doesn’t feel as though it was modernized well here. The main issue stems from how the movement controls interact with the shifting camera.
In Parasite Mutant, you have free analog movement, which sounds modern, but it actually creates some issues. When the camera snaps to a new perspective, your control stick is often still pointing in the direction of the previous shot. This leads to moments where Nova starts running in circles or walking back into the frame you just left because the game can’t quite keep up with the transition.
In classic PlayStation 1 titles, tank controls were used specifically to solve this problem. Since your character always moved forward based on their orientation rather than the camera’s, the controls stayed consistent no matter how much the angle changed. But here, the more modern control scheme ironically causes navigating the island city to feel more clunky than it needs to be.
Despite all of these, the game does feature some genuinely interesting puzzles that feel like a throwback to the survival horror peak of the ‘90s. What I appreciated most was that these avoid the overly convoluted and nonsensical designs seen in, say, modern Resident Evil titles. That is, instead of looking for a random jewel in some family’s house to place in a statue’s eye just to open a bedroom, the puzzles here feel more grounded in the setting.
They also often require you to look into the lives of the people who inhabited the island city before the catastrophe. You progress by piecing together clues found in the environment.
There is still a bit of disconnect in that some of the notes don’t really sound like they were written by actual humans, but the effort to tie the puzzles to world-building is still a nice touch.
Two Bars are Better than One
Since Parasite Mutant follows so closely in the footsteps of Parasite Eve, it’s no surprise that the gameplay feels like a direct evolution of that specific style. As you move around the world, battles occur somewhat randomly, and the game shifts into an active turn-based system. Actions are managed by what the developers call Active Time Chains, or ATC, which is clearly inspired by the Active Time Battle (ATB) system that Square used in games like the original Final Fantasy titles back in the ’90s. The idea is familiar: gauges fill over time, and when they do, you choose how to act, whether with attacks, items, or special skills.
The main difference here is that Parasite Mutant gives you two bars to work with instead of just one. During fights, the gauge fills in segments, and players can decide when to act within those segments. Basic attacks use one bar, while items and special abilities require two bars. This creates some interesting tactical possibilities. For example, you can chain two knife attacks together so the second hit does more damage, or mix a knife attack with a ranged shot so that the first move closes the distance and the second finishes the enemy.
Right now, the demo limits the variety of weapons, so you can’t experiment much, but the system itself shows promise. It feels like a natural evolution of Parasite Eve’s combat in somewhat the same way that Final Fantasy VII Remake expanded on the original ATB-based battles.
However, Final Fantasy VII Remake this is not. Having more options doesn’t necessarily mean the game is now faster or offers more freedom than the original Parasite Eve. You’ll still find yourself dodging projectiles and circling around mutated creatures while waiting for those gauges to fill up. If you don’t have a bar ready, you are basically defenseless other than your ability to lightly jog out of the way.
Sure, this captures the tension of Parasite Eve, but it can also feel a bit sluggish in 2026. Without the right balance of customization and faster gauge-building options in the full release, there’s a risk that the combat could become repetitive.
I’m hopeful that the full game will introduce more ways to interact with the ATC system, like gear that speeds up the bars or upgrades that reward certain actions. The demo shows a lot of heart and a clear understanding of why we liked these games in the first place, but the execution still needs that final layer of polish to make it feel truly snappy. If they can nail the complexity of the customization, they’ll have a great evolution of the genre on their hands.
Rough Edges on a Solid Foundation
Since this is a demo, it is only fair to keep certain expectations in check regarding the technical polish. There are some very obvious work-in-progress issues that crop up throughout the experience. For example, some of the dialogue text frequently overflows or clips outside of the UI boxes, which can make reading certain lines difficult. This is a common enough hurdle in indie development, but it definitely pulls you out of the immersion when the interface feels unorganized.
The audio presentation is another area that feels like it needs a significant amount of work before launch. I actually quite like the soundtrack; the music is moody and fits the atmosphere well. However, the sound effects themselves don't currently match that quality. They feel very thin and are often drowned out by the background music. There’s an unevenness to it; it’s fine to pay homage to 90s audio limitations, but when the music sounds high-fidelity and the sound effects don’t, the contrast is too noticeable.
Despite the laundry list of issues I’ve pointed out, I genuinely have high hopes for the final product. The developers have stated that this demo only covers about 5% of the total content, which is a very small slice of what they are trying to achieve. Although I spent a good portion of this review focusing on the flaws, that comes from a place of wanting the game to succeed.
I am still optimistic about where Parasite Mutant is headed. The foundation is solid, and the passion for the source material is undeniable. If IceSitruuna can use the time leading up to release to sharpen certain things, they might have something special on their hands. I really hope the full release proves my current criticisms wrong and delivers an experience that becomes just as much of a cult classic as the games that inspired it.
