About the base game:
Atomic Heart is an upcoming action-adventure game developed by Mundfish. Set in an alternate version of the Soviet Union, the game follows agent P-3 in a mission to investigate a secret facility where strange and inexplicable phenomena have been occurring. Players explore vast open-worlds, battle robotic enemies and mutated creatures, solve puzzles, and use technology to progress through the story. Atomic Heart features an advanced physics engine that makes for dynamic and interactive environments; objects can be destroyed or interacted with to create unexpected reactions that alter the environment.
Alternate universe
Explore the world after a global system failure, which had happened at the Soviet Facility. That unfortunate event caused the pervasive machinery to rebel against humankind. Take on the role of Major P-3, who’s on a mission to investigate the mysterious accident, eliminate its consequences, and prevent the leakage of information into the wrong hands.
The unknown enemy
Before you decide to stand for a battle against the monstrosities created by the large-scale incident, you should first study their behavior. If you observe how they behave and relate to each other, you’ll take advantage of being one step ahead of the enemies. A clever way to avoid robots’ attacks is to hack their system – use your skills to hack the “Kollektiv” network and remain unnoticed.
