Mewgenics, a roguelike tactical RPG from indie developers Edmund McMillen and Tyler Glaiel, launched in February 2026. The game centers on breeding cats to create stronger offspring, equipping them with collars that assign classes such as fighter, tank, and mage, and leading a mutant cat army through turn-based battles. It features over 1,000 unique abilities and more than 900 items, with skills and mutations inherited by the next generation of cats.

On August 13, 2026, the developers announced that the game now supports Japanese, along with Simplified Chinese, Korean, and Russian, in a public beta on Steam. The beta is accessible by selecting the beta branch in the game's Steam properties. The Japanese localization addresses a long-standing request from Japanese players who previously had to rely on community translations or play in English.

A review from Denfaminicogamer describes the game as a vulgar yet compelling mix of tactics and cat breeding, with a darkly comedic tone. The review details a mad scientist forcing players to choose two of three cats, with the unchosen one disposed of via guillotine and chainsaw. The game combines tactics battles against rats with a breeding and life cycle loop, where cats mate and produce kittens that grow into adults within a day.
