The Binding of Isaac creator's new roguelike Mewgenics already has over a third of the achievements of Isaac despite it being 11 years and 3 expansions ahead

Edmund McMillen has posted an image on social media striking fear into the hearts of many – Mewgenics will have 280 achievements on Steam at launch.

After first being announced in 2012, Mewgenics is finally releasing next month on February 10, 2026. The game was cancelled in 2016, but subsequently rebooted back in 2018, and since then McMillen has been hyping it up as his opus, noting that The Binding of Isaac – perhaps the best roguelike game of all time – was only a practise run of a "basic roguelike" to "get my feet in the water" of the genre. McMillen recently said you may just see "a turn-based game with cats fucking," but described Mewgenics as "very D&D."

And Mewgenics seems predictably big, as McMillen recently took to Twitter to tease one major part of the game. McMillen didn't say anything in the tweet, rather he simply posted a screenshot that says "number of achievements: 280"

For comparison's sake, The Binding of Isaac: Rebirth, which is over 11 years old and has had three expansions (with another in open Beta) currently has 641 achievements, so the prospect of Mewgenics at its base having over a third of that is frankly, scary.

And as someone who has played 258 hours of The Binding of Isaac: Rebirth I only have 359 of those, roughly 56%, I can't imagine I have a hope of completion. And considering McMillen previously said, "I think we will have a few DLCs to make," that number will only grow.

AAA lets indie games take big risks, says The Binding of Isaac creator Edmund McMillen, then "the mainstream grabs what worked" and "cashes in" the "safe way."
