After 14 years in development hell, Mewgenics has devoured the competition. Within hours of its launch, Edmund McMillen’s “cat breeding magnum opus” turned a profit, recouping years of development costs before the first day was even over and becoming 2026’s first legitimate Game of the Year contender.

Within just three hours of its February 10 launch, Mewgenics recouped its entire 8-year production budget. Selling over 152,000 copies in under six hours, it obliterated the records of its legendary predecessor, The Binding of Isaac: Rebirth.
For a game that spent over a decade in development hell, this financial explosion proves that Edward McMillen and Tyler Glaiel’s hold on indie gaming is far from over, but rather entering its final, most grotesque form.

Mewgenics: The Dark Reign of the Mutant Cat Sim
Beyond the hype, Mewgenics delivers a mechanical depth rarely seen in the genre. It offers a 200-hour campaign featuring over 1,000 unique abilities and 900 items, ensuring no two runs are ever remotely similar.
Players must master a complex 10×10 grid-based tactical system where positioning is everything, and a single mistake can lead to the permanent “retirement” of a prized genetic line.
It’s a punishing, systems-heavy RPG where you don’t just play, you optimize a bloodline of mutant feline warriors to survive the madness of Boon County.
Mewgenics vs Hades 2: Dethroning the Roguelike King
The most shocking headline of the launch week isn’t just the sales, but the sheer volume of active players. Mewgenics has officially achieved what many thought impossible, surpassing the all-time concurrent player peak of Hades 2 to become the most-played roguelite ever on Steam.
On February 15, 2026, the cat-breeding sim hit 115,428 concurrent players, narrowly edging out the 112,947 record set by Supergiant’s titan. This shift in player trend signals a massive appetite for the “unhealthy” depth and darker complexity that McMillen and Tyler Glaiel have spent years refining.
Despite its current PC exclusivity, the Mewgenics empire is already expanding. Co-creator Edmund McMillen has confirmed that console ports are actively in development, with the Switch 2 cited as the primary focus.
Furthermore, the team has teased that DLC plans are already in motion to expand the game’s staggering content library even further.
For those waiting on Xbox or PlayStation versions, the developers have noted that the game’s massive financial success gives them the total freedom to target “all systems” as they move into the summer.
Embracing the Chaos of the Decade
Mewgenics is a rare masterpiece that rewards your time with infinite tactical permutations and dark, addictive progression gameplay. While console players will have to wait until later in 2026, PC gamers are currently participating in the most significant indie launch of the decade.
If you have any love for deep strategy, genetic tinkering, or the grotesque charm only indie games can muster,” this could be your new obsession.
