Each episode of The Simpsons has its own version of the intro, giving the characters their own joke. A new roguelike on Steam does the same, although hardly anyone sees it.
What is this Steam hit? The new game Mewgenics is currently a hit on Steam. With over 80,000 players on the day after its release and better revenue than Counter-Strike 2 and Apex Legends on Steam, the indie game can currently (February 12, 2026) crown itself.
In the game, you control an army of cats that become stronger in turn-based battles against enemies. Through battles, the cats gather genetic changes that they can also pass on to provide the next generation with even better conditions.
Thus, the tactical game sold over 500,000 copies within 36 hours, becoming a mega success for the developers. However, of the 500,000 players, only a few have likely seen a secret unfolding right before their eyes.
Here you can see the trailer for Mewgenics:
200 Intros but hardly anyone sees them
What’s up with the intros? Developer Edmund McMillen revealed in a video on YouTube that every intro of Mewgenics is slightly different. Just like in The Simpsons, he says, each intro has its own “couch joke.”
This refers to the details that always change in the intro. In the intros of Mewgenics, there is always a different cat, which might even mutate or be dead, while in other cases, there is graffiti saying “Fat” on the developer’s gravestone in the intro.
In total, there should be about 200 different intros in the game, and each game start should play a different one. So if you want to see all the intros, you need to start Mewgenics at least 200 times.
Why do hardly anyone see the intros? While the intros in The Simpsons have achieved a cult status, video game intros are traditionally skipped right away.
Developer Edmund McMillen knows this too, as he mentions in a YouTube video about a conversation with co-developer Tyler Glaiel. Glaiel is said to have said, “No one will know, they will never watch it a second time.”
Even though the intros are uniquely designed, without the developer’s hint, this feature might have remained an open secret for some time.
Mewgenics is not only successful on Steam but also popular. The title enjoys an excellent rating, which is likely to make the developers just as happy as the financial blessing that the game brings: Over 250,000 sales: Mewgenics only needed 3 hours on Steam to recoup the entire budget of 14 years of development time.
