Enchantment Under the Sea DLC#3 is included in the Atomic Pass, Gold and Ultimate Edition. Requires the base game Atomic Heart to run.
Get back to the spectacular Atomic Heart gameplay as the third DLC sees Major P-3 leave the world of Limbo and return to Facility 3826! Continue the main storyline with the Twins’ consciousness at your side and dive to the underwater Neptune Research Center to find a way to save humanity from a dismal future. Meet new and returning characters and gain access to a new arsenal to dismantle sea-dwelling threats.
The Enchantment Under the Sea DLC#3 features:
• Continuation of the story in a new underwater complex full of new exciting characters and enemies. Explore its mysteries and help P-3 and the Twin to regain what was lost. Also, revisit some familiar locations that have changed beyond recognition, like the flying city of Chelomey, now under the robots’ total control, and other surprises.
• Two new glove skills, expanding the gameplay. Whip skill, a grapple-hook tool, allowing P-3 to pull himself towards the enemies while also giving access to unreachable areas or letting him quickly dodge away from danger. Blaze, a burning polymer skill letting you drop red-hot fireballs and deal area-of-effect damage.
• Two new weapons to take down deep-sea threats. Unlock the Thunderclap, a powerful hammer that amps up damage with electrical current, and the KM-4 Kuzmich, a crowd-clearing double-barrel shotgun with customizable bullet spread.
• New enemies and powerful bosses. Face off against enhanced versions of the robots from the Facility and fight against a new roster of enemies, from Robogirl, that now poses a serious threat, to swarms of sea-dwelling mutants and the terrifying MOR-4Y lurking in the dark depths.
