Atomic Heart - Enchantment Under the Sea is an action, RPG, and adventure title for PC that continues the story of Major P-3 in a new underwater setting. Players control the protagonist alongside the Twins' consciousness while exploring the Neptune Research Center and altered versions of prior locations such as the flying city of Chelomey.
Gameplay
The core loop centers on exploration, combat, and ability use within a linear structure that emphasizes steady forward progress through facility corridors and open underwater zones. P-3 gains two new glove skills that integrate directly into movement and offense. The Whip functions as a grapple tool to close distance on foes, reach elevated or distant platforms, and execute quick retreats. Blaze deploys red-hot fireballs for area damage against grouped threats.
Combat expands with two additional weapons. The Thunderclap hammer channels electrical current to increase strike power against armored targets. The KM-4 Kuzmich double-barrel shotgun allows adjustable bullet spread for clearing clusters of enemies at close range. Encounters feature enhanced Facility robots alongside fresh opponents including the Robogirl, packs of sea-dwelling mutants, and the deep-dwelling MOR-4Y boss that demands careful positioning and skill timing.
Story progression involves interaction with returning and new characters while uncovering details about the research center and broader threats to humanity. Navigation mixes standard traversal with the new Whip for vertical and horizontal reach in the submerged environment.
Game Modes
The experience consists of a single-player story campaign that builds directly on the base game's narrative. There are no separate competitive, cooperative, or survival modes. Progression follows a linear path through the new complex with optional exploration of changed familiar areas, all resolved through combat, ability experimentation, and environmental interaction.
Story and Setting
After events in Limbo, P-3 returns to Facility 3826 and descends into the Neptune Research Center. The Twins remain present as companions while the pair seeks a path to alter humanity's outlook. The setting blends the original game's retro-futuristic aesthetic with submerged laboratories, mutated marine life, and robot-controlled zones that have evolved since prior visits.
Key locations include the primary underwater facility and the robot-dominated Chelomey, now presenting altered layouts and new hazards. Narrative beats introduce fresh characters and expand on existing threads without requiring prior knowledge beyond the core campaign.
Is It Worth Playing?
This title suits players who enjoy first-person action with integrated melee, ranged, and ability systems in a focused story context. The addition of the Whip and Blaze skills, along with the Thunderclap and KM-4 Kuzmich weapons, provides tangible variety in how encounters are approached. New enemy types and the MOR-4Y encounter test adaptation to the underwater layout and vertical movement options.
Those seeking a direct continuation of the Atomic Heart narrative with expanded combat tools will find consistent pacing and fresh challenges. The linear design keeps momentum high while still offering room for ability experimentation against varied threats. Availability on PC supports straightforward access for anyone who has completed the base campaign and wants more of the same core systems in a new environment.
