Atomic Heart 2 Unveiled: Summer Game Fest 2025 Showcases Next-Gen RPG Shooter and Multiplayer Spin-Off

Atomic Heart 2: Taking Retrofuturism to New Levels

Summer Game Fest 2025 delivered a shockwave for sci-fi shooter fans: Mundfish is back with Atomic Heart 2, pushing its weird blend of alternate history, advanced robotics, and chaotic storytelling even further. Gamers who ventured into the bizarre Soviet-flavored universe of the first game will find the sequel cranking up the stakes. Imagine a world where the lines between man and machine blur so deeply that disaster is always a hair’s breadth away. The new chapter picks up with society teetering on the edge, mixing intense FPS action with a stronger focus on role-playing than ever before.

This time around, Mundfish is ditching the mostly linear action for deeper RPG features. They’re teasing more meaningful decision-making, expanded customization, and skills that shape your path—although the developers are still keeping tight-lipped about the exact mechanics. What’s clear is that players can expect fresh arsenals, wild abilities, and locations that stretch the imagination. Think overgrown labs, collapsing science cities, and secret bunkers humming with rogue AI. The early trailers ooze style: chunky analog machines, pastel-hued robots, and surreal landscapes that look ripped from a fever dream about 1950s science propaganda.

But it’s not just about pretty visuals or new guns. Mundfish hinted that storytelling is now front and center, promising that players will be wrapped in mysteries and choices that echo through the crumbling world. Expect branching quests, deeper character backgrounds, and plenty of philosophical questions about technology and control. For fans who wanted more out of the first game’s narrative potential, Atomic Heart 2 is shaping up to be a direct response.

The Cube: A Multiplayer Dive into Atomic Heart

Surprise didn’t stop with the main sequel. Alongside the single-player experience, Mundfish shared an entirely separate multiplayer project, The Cube. Here’s the twist: it’s an MMORPG shooter—set in the same unsettling universe, but built for cooperative and competitive online events. The game’s big centerpiece is a mysterious monolith, earning the nickname ‘The Cube’, which will anchor all kinds of in-game activities and challenges. This isn’t your typical battle royale or one-off co-op mode. Mundfish wants The Cube to stand as its own experiment, testing how the Atomic Heart world bends when real players—rather than just rogue robots—are making the chaos.

While big gameplay features for The Cube are still mostly under wraps, the early pitch is all about high-stakes events, evolving challenges, and a world that changes as players interact with the unknown technology at the heart of the game. Fans hungry for a social, unpredictable experience inside the Atomic Heart universe suddenly have a lot to look forward to.

Both titles are in development for PC and current-gen consoles, but fans will have to wait a bit longer for release dates. Mundfish is playing things close to the vest, but they’re promising that both projects will share the franchise’s signature look—think retro gadgets, dystopian vibes, and an uneasy mix of nostalgia and terror. For anyone who’s followed the series, this double reveal signals Mundfish’s big ambitions: a single-player epic with RPG heart, and a multiplayer sandbox where chaos reigns. The only thing missing now is a concrete launch window—and a chance to get lost in that surreal, shuddering universe once more.
