Mewgenics

Mewgenics added official Japanese display support in an update on September 6 and 7, 2026, joining Korean, Russian, and Simplified Chinese shortly before the console version launches September 8, 2026 on PS5, Xbox Series X|S, and Nintendo Switch 2.

Synthesized from 3 Yomimono stories · updated Sep 11

Mewgenics began as a cat-breeding roguelike tactical RPG from Edmund McMillen and Tyler Glaiel, launched on Steam in February 2026. It held a Metacritic score of 88 at launch and has since settled at 88, with Steam user reviews at 89 percent positive. The game tasks players with breeding cats to create stronger offspring, equipping them with collars that assign classes like fighter, tank, and mage, and leading a mutant cat army through turn-based battles.

Through August 2026, the game lacked official Japanese display support, and the localization arrived first as a public beta. On August 13, 2026, the developers announced that Japanese, along with Simplified Chinese, Korean, and Russian, was available in a Steam beta branch. At that time the game was priced at 3,400 yen tax included on PC via Steam.

The full release of those languages followed on September 6 and 7, 2026, as an update distributed ahead of the console launch. That same update now supports Japanese, Korean, Russian, and Simplified Chinese outside the beta. The console version launches September 8, 2026 on PS5, Xbox Series X|S, and Nintendo Switch 2, with Steam account linking for save data transfer on all three platforms. The Switch 2 version supports Joy-Con 2 mouse and touchscreen controls, while the PS5 version uses the DualSense touchpad. The developers also confirmed a small free update adding new play styles and unlockable items, plus the game's first DLC, with details promised later this year.

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.
