Mewgenics
Mewgenics is Edmund McMillen and Tyler Glaiel's cat-breeding tactics roguelite, out on Steam since 10 February 2026. You breed cats, send a team through turn-based adventures in places like The Alley and The Sewers, and the kittens carry the best and worst of their parents into the next run.

Overview
Furniture sets five house stats, and each one pushes something different. Comfort affects how often cats breed or fight, Stimulation the quality of newborn kittens, and Health lifespan plus the nightly chance to develop or cure a disorder. Mutation adds a chance of random mutations each night, and Appeal improves the strays that show up each day. Breeding is where build choices carry over: upgraded Skill Share makes kittens always inherit your other passive. There are 14 collars, with Fighter, Hunter, Mage, Tank and Collarless open from the start. Gear gets its bonuses from 98 item sets, each needing 3 pieces on one cat, and the Rune of Perthro counts toward every one.
