Atomic Heart is a 2023 first-person shooter video game developed by Mundfish Studio. It was published by VK Play, Focus Entertainment, and 4Divinity.
The game is set in an alternate history version of the Soviet Union, during the 1950s. Initially depicted as a Retrofuturism utopia, the game follows the collapse of the Soviet Union after a AI takeover.
Atomic Heart was released for PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S on February 21, 2023. It gained several awards.
A sequel, titled Atomic Heart 2, is in development.
The player wears a special glove, the Polymer Glove, which grants powers such as telekinesis, freezing, shield, electricity and others to defeat foes. Its powers can be combined with both melee and ranged weapons.
Weapons can be upgraded and embedded with various elemental effects using cartridges. These cartridges can be looted, crafted and equipped by the player on both melee and ranged weapons.
To cover distances faster in certain large open spaces, players can use cars left in these areas. Players also have to solve various puzzles that are encountered throughout the main campaign and side Polygons (Testing Grounds). After one of the released patches in June 2024, the game also offers accessibility settings, which include not only puzzles auto-solve, but also colorblind mode, auto QTE, auto-heal, and some others.
Sechenov later developed the THOUGHT, a neuroconnector that integrates Polymer into the human body, enabling direct interaction with robots. Designed to launch alongside Kollektiv 2.0, it was intended to usher in a true post-labor era. However, the launch resulted in a catastrophic failure, plunging Facility 3826 into chaos.
P-3 finds Petrov working with neurosurgeon Larisa Filatova, but Petrov seemingly dies while fleeing. Suspicious of Facility 3826, the Politburo sends Yegor Molotov, who threatens to halt the launch of Kollektiv 2.0. CHAR-les reveals a power struggle over Kollektiv between Sechenov and the Politburo. Sechenov orders P-3 to accompany Molotov, but P-3 blacks out and later finds Molotov murdered. Sechenov then reveals that Petrov is alive, having faked his death with Filatova’s help.
P-3 finds Petrov at the Theater, where Petrov reveals that civilian robots always had a combat mode secretly installed and accuses Sechenov of planning to use them for global domination. He gives P-3 a pair of rings before committing suicide. Suspecting the "Atomic Heart" project involves deploying combat robots to seize nuclear plants, P-3 takes Petrov's head to Michael Stockhausen, Sechenov's deputy, for memory extraction. However, Filatova intervenes and throws a grenade, resulting in Stockhausen’s death and knocking P-3 unconscious. CHAR-les reveals that the rings are top-secret devices which allow the wearer to join Kollektiv 2.0 while remaining "invisible" to the network, thus gaining unrestricted authority and control within the Kollektiv.
When P-3 wakes up, Filatova contacts him and meets him in secret at a secluded area in Facility 3826. She reveals to him that Kollektiv is a means to mind-control people, and Filatova was in charge of the facility that houses numerous volunteers of the project. P-3 also discovers that CHAR-les isn't an AI, but rather the preserved consciousness of Chariton Zakharov, Sechenov's colleague and a fellow researcher presumably murdered by Sechenov. Using Zakharov's security clearance, they uncover more of P-3's past: he was previously critically injured in a mission in Bulgaria alongside his wife and fellow agent, Ekaterina "Blesna" Nechayeva. While Blesna did not survive, Sechenov managed to fix P-3's brain injury by installing a Polymer implant, erasing memories of Blesna while also implanting her memories into robotic ballerina bodyguards called the Twins. In doing so, Sechenov gains control over P-3. Furious, P-3 decides to confront Sechenov. However, he blacks out again and wakes up in the care of his mother-in-law, Zinaida Muravyova, who has been anonymously assisting him throughout his mission in Facility 3826. She reveals that P-3 had killed Filatova while blacked out. At this point, P-3 can either choose to leave Facility 3826 or confront Sechenov, resulting in different endings.
If P-3 refuses to confront Sechenov, he destroys Zakharov and slips out of Facility 3826 and disappears, allowing Sechenov to continue with his plans to activate Kollektiv 2.0. Zakharov is shown to still be alive as a small mass of living Polymer and he manages to escape as well.
If P-3 chooses to confront Sechenov, he enters his office, where they argue before Sechenov orders the Twins to attack. After P-3 defeats them, Sechenov draws a pistol, but P-3 uses his glove to disarm him and shoots him in the gut. Wounded, Sechenov reveals that Zakharov manipulated P-3’s blackouts, making him unknowingly kill Molotov and Filatova. Enraged, P-3 tries to remove Zakharov from his glove, but Zakharov electrocutes him and escapes as a gray mass. Declaring his intent to exterminate humanity, Zakharov jumps into a vat of red Polymer, transforming into a massive black humanoid. He then picks up Sechenov, breaks his neck, and later consumes his body before vanishing. P-3 later awakens in an illusion, where one of the Twins reaches out to him as Blesna’s voice speaks.
NORA tempts P-3 with secrets about Blesna, but Lebedev connects him to Sechenov, who reveals that he preserved Blesna's brain in neuropolymer to revive her. He offers P-3 full access to his past and a leave of absence. P-3 agrees, resets NORA with the Twins' help, and restores order. As promised, Sechenov grants him leave, but as P-3 departs, Zinaida follows.
At Triton, P-3 and Blesna meet new allies: technician Nikolai, cetologist Nastya, and security officer Hunter. After helping them relocate a school of dolphins, one is assigned to retrieve the rings. Zinaida later sends one of the Twins’ bodies to Triton, upsetting Blesna. Nikolai reveals he was sent to deliver Samodelkin, a high-tech repair system created by Dr. Lebedev, and identifies Blesna as its key activator. With Samodelkin, P-3 repairs his arm and links it to Blesna.
As the group prepares to escape Triton, P-3 and Blesna are intercepted by MOR-4Y, a gigantic eel robot roaming the facility. Blesna, through Samodelkin's connection, transfers her consciousness to the Twin robot body, and assists P-3 in destroying MOR-4Y. The dolphin later returns and gives P-3 the rings, which he then puts on Blesna's hand. After taking a moment of respite on the surface, P-3 decides they are ready to pursue Zakharov.
Bagratuni and Galeev have known each other since the early 2000s, having worked at advertising companies. Bagratuni focused on marketing, while Galeev specialized in computer graphics. After the economic downturn in 2008, when the advertising market collapsed, the share of video games increased. Sedova and Bagratuni met at the company Newmedia Stars. Before merging with Galeev and founding the game studio Mundfish, they had completed several joint projects. The key figures at Mundfish do not have direct ties to Russia or its president, Vladimir Putin.
Mundfish has the main office in Cyprus and development offices in Abu Dhabi and Yerevan. At the age of 19, a producer Oleg Gorodishenin joined the studio (listed in Forbes 30 Under 30 in 2023). The development of Atomic Heart was initially funded by Bagratuni, Sedova, and non-public shareholders. According to Crunchbase, Mundfish raised $16 million in two investment rounds in 2019 and 2021. According to Forbes, the amount from the Chinese investment holding Tencent, the international investment company GEM Capital, and the founder of the game studio Gaijin Entertainment, Anton Yudintsev, could be around $20 million.
In the summer of 2018, Nvidia offered Mundfish Studio to release the game on the Nvidia RTX, which supports ray tracing and DLSS technology for GeForce RTX graphics cards. They provided their equipment, access to a special version of the Unreal Engine 4, and tools for the game's implementation. Nvidia partially took on the marketing promotion, showcasing RTX capabilities at maximum settings in an Atomic Heart trailer at the Gamescom gaming convention in Cologne. However, ray tracing was not implemented at the time of release. It was added in a beta version after an update on June 11, 2024.
Along with the original tracks created solely for the game, Atomic Heart also features popular Soviet songs and their remixes, including "Arlekino" and "Zvyozdnoye leto" by Alla Pugacheva, "Trava u doma" by Zemlyane, "Kosil Yas' Konyushinu" by Pesniary and more.
The game's music composer Mick Gordon released a statement condemning the Russian invasion of Ukraine and donating his fee from the project to the Red Cross Ukraine Crisis appeal.
The game's first DLC expansion, titled Annihilation Instinct, was released on all platforms on August 2, 2023. The second DLC, Trapped in Limbo, was released on February 6, 2024. The third DLC, Enchantment Under the Sea, was released on January 28, 2025. It introduced new weapons, abilities, and allowed players to explore the underwater Triton complex. In November 2024, a collaboration with artist Taras Yoom was announced to coincide with the DLC release. Yoom unveiled limited-edition sculptures, "Comrade and Union," which were integrated into the expansion.
In May 2025, Mundfish announced that Atomic Heart had surpassed 10 million players worldwide.
The studio is carefully distancing from Russian political statements. Many game developers and publishers have spoken out against the war, stopped selling games in Russia and Belarus, and donated to humanitarian causes. The Ukrainian Ministry of Digital Transformation critiqued Mundfish, noting that "the developers of the game did not come out with a public statement condemning the Putin regime" and the Russian invasion of Ukraine, also pointing out that the game has "Russian roots and romanticizes communist ideology and the Soviet Union." The February 21 release date drew criticism because it nearly coinciding with the first year anniversary of the 2022 Russian invasion of Ukraine and Defender of the Fatherland Day, on February 24 and 23 respectively. Developer Mundfish stated that the company is neutral in world affairs and "do not comment on politics or religion". Mundfish also added that the studio "is undeniably a pro-peace organization against violence against people".
Mundfish has been accused of collecting data of users based in Russia and providing it to the Federal Security Service. The developer denied these allegations, stating: "Our game and website DO NOT collect any information or data. The website’s privacy statement is outdated and wrong, and should have been removed years ago." In January 2023, the studio replaced the Russian-language Privacy Policy on the website with an English-language version, removing all mentions of Russia.
IGN praised Atomic Heart for being "deeply ambitious, highly imaginative, and consistently impressive", though criticized its writing and "tedious" elements of gameplay, such as fetch quests. PC Gamer called it "one of the oddest" AAA games. They felt it took primary influence from BioShock, but criticized its combat and progression system as inferior, while being conflicted towards the story and characters. Similarly, Polygon felt that Atomic Heart failed to eclipse BioShock through its gameplay and attempts to tackle multiple themes at once.
"Playing the game, the player will be left with no doubt as to the dark side of Soviet manifest destiny. The central conflict is between the Politburo and Sechenov. The implication is that the latter is a power-hungry madman who has poisoned the Communist dream. Whatever Atomic Heart is, it isn't a love letter to the Soviet Union. This is a paradise lost, fatally undone by its Prometheus complex."
Journalist Kevin Purdy of Ars Technica wrote that within the game:
The USSR makes the world's best robots, its citizens live in a utopia where those robots do their menial tasks and labor, and even greater things are just about to happen...a world full of astounding promises, yet take apart that optimism by showing the hypocrisy, the false promises, the ego-driven leaders and actors causing so much pain, and the impact on real people's lives when it all comes apart...The Soviet State in Atomic Heart, and its maniacal leaders, are responsible for the death of untold thousands or millions of citizens at the hands of their own robots. There are plans to foist this death on the rest of the world, rather than win them over with the benefits of collectivist effort. The KGB, for which your protagonist formerly worked, are not the good guys.
Jason Faulkner of GameRevolution felt that while the game is frequently critical of the Soviet Union, it stops short of ever outright condemning it. Renata Price of Vice News also wrote that the game "depicts a scenario where the Soviet Union's quest for technology and expansion—there are numerous sarcastic references to conquering the stars—has gone horribly, murderously wrong...To call Atomic Heart a straight-up celebration of the Soviet Union would be a misrepresentation."
