# Mewgenics: the cat game from the maker of The Binding of Isaac

Source: https://roam.new/mewgenics/. Checked November 3, 2026.

Mewgenics is a tactics roguelike about breeding cats and sending them to fight, made by Edmund McMillen, creator of The Binding of Isaac, and Tyler Glaiel, co-creator of The End Is Nigh. It came out on Steam on February 10, 2026, sold over a million copies in its first week, and reached consoles in September. It is cute on the surface and very strange underneath.

## How the two halves fit together

At home you keep a house full of cats. Cats pair up and have kittens, and kittens inherit traits, abilities and sometimes odd mutations from their parents. Picking which cats breed is a long game: you are trying to raise a line of fighters that suits your style.

Then you pick a team and send it out on a run. Adventures play as turn-based tactical battles on a grid, against monsters and bosses. Cats can be hurt, changed or lost on the way, so each run feeds back into the house. A strong cat that comes home can pass its best traits on.

The humor is classic McMillen: gross, dark and silly at once. It is not a cozy pet game, even if the cover looks like one.


## Tips for your first runs

- **Breed with a plan**: Pick one or two traits you want and keep pairing cats that carry them.
- **Do not send your best cat every time**: A great breeder is worth more at home than on a risky run.
- **Use the grid**: Position matters more than raw power in tactical fights.
- **Expect losses**: It is a roguelike. Failed runs still teach you which cats work.

## Where to play it

Mewgenics came out on PC through Steam at $29.99. On September 8, 2026, Nicalis brought it to PS5, Xbox Series X|S and Nintendo Switch 2 as a $39.99 download with the same content and cross-save with Steam. It is not on phones.
