Mundfish just cranked the hype up to eleven at Summer Game Fest 2025 with the official reveal of Atomic Heart 2, and yes—it’s set to the legendary beat of Queen’s “Don’t Stop Me Now.” The sequel to the studio’s wild, retrofuturistic FPS is officially in development for PC and consoles, and it looks even more unhinged than the original.
The announcement lands hot on the heels of Atomic Heart hitting a massive milestone: over 10 million players worldwide. To celebrate, Mundfish dropped a slick new trailer that teases exotic new locales, a fresh lineup of characters, expanded abilities, and a peek at what’s waiting in this chaotic new chapter of their alternate-history universe.
According to Mundfish founder and game director Robert Bagratuni, the team’s been eager to share the news:
“It’s been hard sitting on this announcement for so long, but today, at Summer Game Fest, we’re incredibly happy to finally and officially announce that Atomic Heart 2 is coming, and it’s bigger and bolder than the original.”
What to Expect in Atomic Heart 2
Much like its predecessor, the sequel blends explosive combat with wild world-building set in a utopian vision of a world ruled by science and AI gone wrong. But this time, the scope is global—and the stakes are higher.
Here’s what we know so far:

-
Expanded RPG Systems
Players will have more freedom than ever before, with deeper RPG mechanics, side content, and a narrative that adapts as you shape your path through the Atomic Universe.
-
New and Returning Faces
The trailer confirmed fan-favorite characters are returning, alongside a new cast that offers fresh perspectives on the world and its unraveling secrets.

Narrative-Driven Chaos
With a focus on mystery, high stakes, and player agency, Atomic Heart 2 is set to deliver another bold story full of twists and moral murk.
