Review
A turn-based tactics roguelite about cats. You breed, raise and equip a team, send it out on isometric, grid-based adventures, and pass traits on to the next generation. Humor is dark and cartoonish, and the runs are procedurally varied. Single player only. Is it your kind of game?
Game Avant verdict
A roguelike tactics game that finds its identity in genetics rather than gear, and mostly earns the ambition it reaches for.

Mewgenics is built on a question most tactics games never think to ask: what if the thing you were optimizing across a whole campaign was not a character's gear, but its bloodline? Edmund McMillen, the creator of The Binding of Isaac, and Tyler Glaiel built a roguelike tactics game around exactly that premise, one that sounds almost too simple on paper to support an entire genre entry, and then proved it was not. Published by Nicalis, it launched for PC on Steam on 10 February 2026, followed by a release on Nintendo Switch 2, PlayStation 5 and Xbox Series X|S on 8 September 2026. The commercial reception left no ambiguity about whether the idea landed with players: the game passed a million copies sold in its first week alone, and its Steam user reviews have stayed strongly positive in the months since launch. None of that commercial success is the actual reason the premise works, though. What makes it work is that genetics, treated here as a genuine strategic system rather than flavor text wrapped around a normal tactics game, turns out to be a legitimately interesting axis to build an entire roguelike around. Instead of recruiting a single hero and levelling them up across a run the way most tactics roguelikes do, you are managing an entire colony of cats across multiple generations at once. Every cat that survives a turn-based adventure can be bred with another cat from your colony, and the traits each parent carries directly determine what the resulting litter is capable of in the next generation, from combat abilities down to the kinds of ability drafts they can access. That breeding layer changes the actual texture of decision-making far more than it first appears to. Ability drafts picked up during individual battles, items collected along the way, and the outcomes of specific tactical encounters all feed back into a single ongoing question: which cats in your current roster are worth breeding forward, and which ones have served their purpose and are better retired before they dilute a strong bloodline. That forces players to think two full steps ahead of whatever fight is currently in front of them, a different and more patient kind of pressure than the turn-by-turn tactical thinking most games in this genre ask for. The systems wrapped around that central idea are genuinely uneven in places, some tactical encounters feel thinner than the breeding system they support, and the humor and tone will not land for every player expecting something more conventional from a cat-themed strategy game. But the core idea, genetics as a real strategic resource rather than a cosmetic gimmick, is ambitious enough and well-executed enough that Mewgenics mostly earns the reach it attempts, finding an identity few tactics roguelikes have tried to claim before it.
You may love it because
Watching inherited traits shape the next litter makes every planning phase feel personal and earned.
It may frustrate you because
Losing a carefully bred bloodline to permadeath can undo hours of planning in a single unlucky turn.
You may love it because
Battles reward reading the board and drafting the right ability rather than fast hands.
It may frustrate you because
The deliberate pace can feel slow to players who came in expecting the speed of McMillen's earlier games.
You may love it because
Drafted abilities, inherited genetics and collected items mean no two runs play the same way.
It may frustrate you because
Newcomers unfamiliar with breeding-based strategy face a steeper first few hours than a typical tactics game.
