I can’t lie, if you asked me to care about a game by the creator of The Binding of Isaac, even a couple of weeks ago. You wouldn’t get much from me. Even though, on paper, Mewgenics is actually pretty spot-on for me in the kind of games I like.
There’s a very specific style and delivery to his games that doesn’t appeal to me on the outset. Despite the massive praise.
Mewgenics has shattered my own personal hesitations and skepticism, and it took all of maybe 10 minutes to do so. It turns out that judging a book by its cover is pretty stupid. Who knew?
Mewgenics
Originally announced back in the early 2010s before being shelved, resurrected, and meticulously rebuilt, Mewgenics has finally clawed its way onto our screens. Created by Edmund McMillen and Tyler Glaiel (the duo that brought us the punishing platformer The End Is Nigh). This is a project that feels like the culmination of over a decade of design evolution.
While McMillen is best known for the legendary The Binding of Isaac, Mewgenics shifts the focus from twin-stick chaos to something far more cerebral: a tactical, turn-based roguelite centered on the bizarre world of cat breeding and genetic manipulation. Yep. That’s a premise and a half, isn’t it? That’s what piqued my interest. There’s nothing that hits like a tactical turn-based game, then with roguelite elements sprinkled all-over it. How could I not be intrigued?
At its core, Mewgenics is a game of two halves that feed into one another.
One half is a deep, grid-based tactical RPG where you lead a squad of four cats through procedurally generated adventures in Boon County. These felines aren’t just pets; they are specialized warriors belonging to classes like the tanky Fighter, the glass-cannon Mage, or the elusive Hunter.
The combat is remarkably dense, featuring over 1,000 unique abilities and a heavy emphasis on environmental interactions. You aren’t just trading blows; you’re managing positioning, exploiting weather effects, and trying to keep your cats alive—because in this world, death is permanent and injuries carry over.
Aesthetics
If there is one thing that might give a first-time player pause, it is the visual presentation. McMillen has a signature style. Thick lines, hand-drawn vector art, and a penchant for the grotesque—that he has honed since the Newgrounds era.
At a glance, Mewgenics can look a little.…..gross. It is a world filled with mutated felines, stray bodily fluids, and characters that look like they crawled out of a fever dream.
If you’re coming from the polished, photorealistic worlds of modern triple-A gaming, the monochromatic, sketchy aesthetic of Boon County might feel abrasive or even off-putting.
If you look past the surface and find the substance, Mewgenics rewards that effort almost immediately. Once you start your first run, the art style stops being a hurdle and starts being a language.
Those strange visual quirks—an extra head, a peculiar glow, or a lopsided gait—actually serve as vital visual shorthand for the complex genetic traits and mutations affecting your units.
Within an hour, you aren’t seeing “ugly” cats. You’re seeing a highly optimized Mage with a rare “primordial dwarfism” trait that gives them astronomical luck stats. The aesthetic isn’t just a choice; it’s the perfect wrapper for a game that embraces the chaotic, the imperfect, and the weird.
The Mastery of the Bloodline
The real magic happens when you return from an adventure.
Survival isn’t just about the loot you’ve found; it’s about the legacy you bring back to the house. The breeding mechanic is where Mewgenics truly separates itself from the roguelite pack.
By pairing cats with desirable traits, you can influence the next generation of adventurers, attempting to weed out negative birth defects while doubling down on powerful synergies. It turns the “one more run” gameplay loop into a multi-generational saga. You aren’t just playing for the current squad, you’re playing for the kittens that will eventually take their place.
This creates a sense of attachment that is rare in the genre. When a cat you’ve spent three generations “perfecting” finally bites the dust in a swamp battle, it hurts.
But because the game is so generous with its systems and item combinations, that failure usually leads to a new discovery. Maybe that failed run unlocked a new NPC like the Organ Grinder to help retrieve lost items, or perhaps it gave you the currency needed to upgrade your house.
There is a constant sense of progression that makes even your biggest tactical blunders feel like necessary steps in a much larger experiment.
As someone who has a natural aversion to cats, as well. Mewgenics has somehow made me care about these gross-looking felines. I don’t get it. I started, thinking the game look gross and I don’t like cats. Now I want them to survive and breed and succeed.
The generational element certainly reminds me of Rogue Legacy 2, and I always loved that. There’s a lineage, one that matters and it really does help pull you in a little deeper to the world.
Overall
Look, it’s been like 5 hours, so there’s plenty to go at. Mewgenics is a massive undertaking. With a campaign that can easily stretch over 200 hours and a level of depth that rivals the best tactical sims on the market, it is a game that demands your attention but respects your time.
It takes the synergy-driven “break the game” philosophy of The Binding of Isaac or Balatro and applies it to a format that rewards careful thought and long-term planning. It is complex, occasionally gross, and undeniably brilliant.
The combat reminds me massively of Marvel’s Midnight Suns (one of the best in class, for sure!). The breeding and lineage stuff reminds me of Rogue Legacy 2, a game I love. There’s just so much good stuff here, it’s undeniable.
For those who have been waiting since 2012, the wait was more than worth it. For everyone else, don’t let the initial weirdness of the art style deter you. Behind the strange faces and mutated whiskers lies one of the most robust and addictive strategy games of the year.
It is a triumphant reminder that indie gaming is at its best when it’s being unapologetically unique. Where we focus a little too much on thos big releases here, Mewgenics is knocking us on the head to remember that quality can come from anywhere, and let’s be honest, AAA games rarely come out complete anyway.
Man, I didn’t have money on the most surprising game of 2026 being a cat-based tactical roguelite that looks gross. It’ll likely be in the discussion for game of the year if it sticks with me as long as I think it might.
