Despite Facility 3826 now being home to evil robots and infected mutants with a penchant for violence, there’s still some life left in the overrun facility. Whether friend or foe, the Atomic Heart characters you meet as you progress through the Facility and the narrative are the last left alive from the devastation.

Besides getting to know the Atomic Heart characters, you can also find out how much time you’ll be spending with them thanks to our guide on the Atomic Heart length. This guide is based on our experience with the game for our Atomic Heart review.

All Atomic Heart characters

  • P-3/Sergey Alekseyevich Nechaev
  • Dr. Dmitry Sergeyevich Sechenov
  • Larisa Andreyevna Filatova
  • Granny Zina/Zinaida Petrovna Muravyova
  • Michael Stockhausen
  • Viktor Vasilyevich Petrov

Atomic Heart characters: P-3 holding his makeshift buzz saw axe.

Major Sergey Nechaev, better known as P-3 is an experienced soldier and the main character in Atomic Heart. P-3 is a rather gloomy and arrogant individual, thanks to his past. He’s also been equipped with several augments and implants, performed by Dr. Dmitry Sechenov to save his life. Despite this, P-3 believes machines should never be trusted, so it’s no surprise that he’s determined to find out the truth behind the unfolding situation at Facility 3826.

Atomic Heart characters: Dr. Dmitry Sechenov dressed in a shirt and tie looking just past the camera.

In the alternate history universe of Atomic Heart, Dr. Dmitry Sechenov pioneered a powerful substance called Polymer in 1936. He’s also responsible for creating the Kollektiv, a neural network of AI robots that, despite being designed with noble intentions of helping people’s everyday lives, were sabotaged with the launch of Kollektiv 2.0.

Atomic Heart characters: Larisa Filatova looking to the side, showing off her neurosurgeon headset.

Dr. Larisa Filatova is a talented neurosurgeon who, after the death of her mentor, continued to pursue integrating humans and machines into the Kollektiv 2.0 network. Despite her intellect and skills, she’s known for disobeying direct orders from her superiors on several occasions.

Atomic Heart characters: Granny Zina looking to the side.

Coming out of left-field, Zinaida Muravyova, better known as Granny Zina is a battle hardened elderly woman. As a lieutenant colonel and former communications officer for Facility 3826, Granny Zina is strong-willed and has extensive knowledge of the Facility.

Atomic Heart characters: Michael Stockhausen dressed in a suit, looking slightly to the right.

Michael Stockhausen is a German scientist who turned to the USSR in search of opportunity after the war. He quickly ascended through the ranks thanks to his scientific and organisational skills, and was ultimately recruited to Facility 3826 where he soon earned Sechenov’s respect.

Atomic Heart characters: Viktor Petrov examining a small glass box containing an item.

Viktor Petrov is a skilled engineer, roboticist, and programmer who quickly proved himself at the Facility, gaining the respect of Stockhausen and even Sechenov himself. Due to this, he was assigned a leading role in the development of the Kollektiv 2.0 neural network. This didn’t work out though, with him having since been reprimanded and required to do community service after betraying the ideals of the Facility when his ambitions began to threaten society.

Atomic Heart characters: The Left and Right ballerina robot twins dancing.

Left and Right are the robot twins you’ve no doubt seen. They’re Dr. Dmitry Sechenov’s assistants and bodyguards, built to reflect the theatrical nature of ballerinas. Equipped with high-grade technology, these robot twins are highly agile and ready to protect Sechenov.

And that’s all the Atomic Heart characters you’ll meet along the way, from the gruff and rather antagonistic player character P-3 to the deadly Left and Right robot ballerina twins and communications expert Granny Zina.

Developer Mundfish has come under increasing scrutiny in recent weeks after it was alleged that the Russian government stands to gain financially from the release of Atomic Heart. This is due to the fact that investors involved in the financing of Mundfish include GEM Capital, an investment fund whose founder has ties to Gazprom and VTB Bank, both of which are majority-owned by the Russian state.

Mundfish is also partnering with VK (formerly Mail.RU) for the Russian release of Atomic Heart, evading sanctions on Steam – VK is also majority-owned by the Russian state through Gazprombank, and Mundfish’s CEO is a former Creative Director at Mail.RU.

With Russia’s ongoing invasion of Ukraine, many players are now choosing to boycott the game in protest and donate money to organisations like The Ukraine Crisis Appeal, International Rescue Committee, and the British Red Cross.
