Fans of 90’s Saturday morning cartoons take heed! Imagine if the Teenage Mutant Ninja Turtles and the Biker Mice from Mars had a feline makeover and decided to embark on an epic, rogue-like adventure.

Ultra Mega Cats is all about clawing and shooting your way through hordes of enemies in chaotic combat with a purr-pose. After all, who doesn’t love cats in mechs?

Dive whisker-first into Ultra Mega Cats and join the feline frenzy as you take on the role of the Mega Cats. These aren’t your average kitties; they’re on a mission to free the three Ancient feline gods from the clutches of corporate prisons. With Kagero’s ninja stealth and BBkat’s tank-like resilience, you’ll navigate through a labyrinth of randomly generated rooms, each more challenging than the last. And that’s just the beginning – more characters are set to join the fray, each bringing their own unique flair and abilities to the table.

But Ultra Mega Cats isn’t just about flexing those claws and pouncing on enemies. No, sir! It’s a story-rich journey that delves deep into the personalities and tales of each Mega Cat, setting it apart from other roguelikes. This game has heart, soul, and plenty of cat-itude, offering players not just a game, but a fun and chaotic experience where every playthrough is a step closer to restoring cat-topia.

Fear not, for you won’t have to face the dangers alone! Ultra Mega Cats is all about sharing the thrill with your pals, featuring two-player co-op play at Early Access launch, with plans to expand to four by full release. Imagine tearing through enemies with your fur-ever friends by your side, each of you complementing the other’s strengths and weaknesses. Together, you'll work like a well-oiled machine – or should we say, a well-groomed clowder of cats – on your quest to topple the rodent, reptile, and wolf adversaries standing in your way.

Fallen Leaf Studio announced that Ultra Mega Cats is coming to Steam Early Access on June 3, 2025 and will remain so for aprox. 12 to 18 months.

“The Early Access version is already playable. 1 full biome, 2 characters, short- and long-term progression, and co-op are working. We are working on the 2nd biome and making a lot of improvements.”

“Early Access scope content wise is: 4 Coalition of Aspects (short-term progression), 2 playable characters (each with 50 M.O.D.S - our long-term progression), 2 full Biomes (each with 2 bosses and a minimum of 5 different enemy types), and 2 players co-op. In the full version, we plan to have: 5 Coalitions of Aspects, 5 playable characters (each with 50 M.O.D.S. ), 3 full Biomes, and 3–4 players co-op. It’s not set in stone, but we would like to change the game engine from Unreal Engine 4 to Unreal Engine 5 during EA.”
