Mewgenics finally has a release date. After more than a decade of teases, restarts, and reinventions, the oddball cat-breeding roguelike RPG from Edmund McMillen, creator of The Binding of Isaac and Super Meat Boy, launches on February 10, 2026 for PC via Steam.
The date was revealed on September 4, 2025, nearly 13 years after Mewgenics was first announced back in 2012, cementing it as one of the longest-running indie projects in development. To celebrate, McMillen and co-developer Tyler Glaiel hosted a 50-minute gameplay showcase on McMillen’s YouTube channel, walking fans through the game’s tactical, turn-based combat, its chaotic cat-breeding systems, and a grimy-but-charming aesthetic that feels unmistakably McMillen.
Mewgenics has had a winding journey. Originally pitched as a follow-up to Super Meat Boy—an offbeat mix of Pokémon, The Sims, and Animal Crossing—development paused as priorities shifted and The Legend of Bum-bo took center stage. In 2018, McMillen reacquired the rights and rebooted the project with Glaiel, scaling it into a sprawling roguelike packed with depth and long-term replayability.
The current version promises serious scope:
– 200+ hours of gameplay
– 800+ unique items
– 200+ enemies
– 1,200+ abilities
While initially targeting a 2025 release window, the team pushed launch to early 2026 to avoid the crowded holiday season and to ensure a thoroughly polished experience. As McMillen explained on Steam: “Launching in November or December is very complicated. We want the game to get the attention it deserves and not compete with AAA holiday releases. Plus, a few extra months allow us to deliver a more polished and well-tested experience.” That timing also sidesteps major indie headliners like Hollow Knight: Silksong, which continues to generate massive demand.
Expectations are sky-high, and with good reason. The Binding of Isaac: Rebirth holds an Overwhelmingly Positive user score north of 96% on Steam from hundreds of thousands of reviews. VGChartz reports it had shipped nearly 10 million units worldwide by mid-2018, with a steady daily concurrent player base around 25,000 on Steam—testament to McMillen’s ability to build games with staying power.
If the new showcase is any indication, Mewgenics aims to channel that legacy into something even stranger: a deep, systems-driven RPG where breeding bizarre felines isn’t just flavor—it’s the heart of your strategy. With its layered mechanics, grotesque whimsy, and long-tail replayability, February 10, 2026 is shaping up to be a very good day for roguelike fans.
