About Atomic Heart Enchantment Under the Sea

Enchantment Under the Sea DLC#3 is included in the Atomic Pass, Gold and Premium 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.

Atomic Heart Enchantment Under the Sea for PC starts at €5.29 (no fees) at Instant Gaming, a Steam key, which is 47% under the €9.99 (no fees) it costs on the official store.

Is it worth buying the Steam Key for Atomic Heart Enchantment Under the Sea now or waiting?

That €5.29 (no fees) key is at one of its best prices.

  • Those €5.29 (no fees) are 19% below what it usually costs, measured on the store price.

  • Not counting today, the lowest we have recorded for the Steam Key across 451 days is €5.29, and today it sits exactly there.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Most common FAQs when buying Atomic Heart Enchantment Under the Sea for PC in digital format:

As of 26/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Atomic Heart Enchantment Under the Sea on PC is €5.29 (no fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Atomic Heart Enchantment Under the Sea to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Atomic Heart Enchantment Under the Sea, and they will provide a new key. You can also contact us, and we’ll help you out.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.
