Atomic Heart is a science fiction shooter with more than a few nods to the BioShock series. Akin to the BioShock series, Atomic Heart is a big game with lengthy missions to explore and find as the story unfolds.

Featuring over 40 missions with side content of varying lengths, there is enough gameplay in Atomic Heart to keep players happy, entertained, and immersed in the alternative universe USSR where Russian technology and expertise in robotics have surpassed the rest of the world.

Updated August 7, 2023, by Michael Llewellyn: Atomic Heart attained many fans since its launch with its darkly humorous approach to the BioShock formula. It is a popular title on Xbox Game Pass and has left fans wanting more. While a sequel is probably a long way off, Atomic Heart has new story-based DLC to continue the Major's fight against the robots gone rogue. Atomic Heart: Annihilation Instinct features new weapons, abilities, achievements, and more. Now players get more ways to destroy the robots in creative and violent ways. This guide is updated to include the new mission list for Annihilation Instinct and a list of trophies/achievements that includes mission-related objectives and missable combat-related goals to unlock them.
