Mewgenics

Each day in Mewgenics begins at your house in Boon County: you pick a team of cats from your growing roster, equip them with class-defining collars — Fighter, Tank, Mage, and more — and send them out into a turn-based tactical adventure in search of food, money, and items. Combat plays out on a grid where positioning, ability combos, and environmental interactions all matter. Return home alive and those cats bring back scars, experience, and sometimes stranger physical changes; the genetics they carry can then be passed to the next generation, bending your bloodline toward whatever monstrous or magnificent form you’re chasing.

Breeding is what sets Mewgenics apart from conventional tactics roguelikes. Cats are not just units to equip and spend — they are raw material.

Traits, mutations, and quirks inherited across generations compound in ways the player shapes deliberately, and decisions about which cats to keep, breed, or hand off to NPCs for house upgrades ripple forward across the entire campaign. Over a run spanning dozens of hours, this creates a kind of living institutional memory: the squad you field late in the game is a direct product of every choice made earlier.

Built on enormous combinatorial depth — more than a thousand abilities spread across ten-plus classes, hundreds of items, and a large enemy roster — the game is openly designed for experimenters willing to let weird outcomes teach them something. Players who want a clean, legible tactics experience and find emergent chaos frustrating are likely to bounce off it. Early adventures introduce the basics gradually, but the system keeps revealing new layers as breeding chains grow longer and ability interactions become stranger.

Edmund McMillen, known for The Binding of Isaac and Super Meat Boy, developed Mewgenics alongside Tyler Glaiel, co-creator of The End Is Nigh. It released on February 10, 2026. Rapid patch activity followed launch, with multiple updates shipped through February and March 2026 addressing bugs and balance across both the main build and a parallel beta branch. By April 2026 the team had moved into larger balance work on a beta for version 1.1, and that update released in May 2026, with additional beta patches continuing through the same month. Language support was also flagged as a forthcoming area of development in May 2026.
