Atomic Heart: Enchantment Under the Sea Walkthrough — Complete Guide and Tips

The third and penultimate story expansion for Atomic Heart is titled Enchantment Under the Sea. In this adventure, Major Nechaev reunites with what remains of his wife, and together they set out to find the rings previously lost by Sergey at the bottom of a vast lake. In this guide, you will find a detailed walkthrough of the DLC, as well as learn how to collect all upgrades and chirpers.

The game begins in the Sechenov complex, where Nechaev reunites with Blesna, who will assist him throughout the journey. Inspect the tables and find the first chirper "New Chapter". Also, before leaving, you can read the notes on the electronic device.

To get out, you'll need to pick a regular lock. If you played the main game and previous expansions, it shouldn't be a problem. Move forward and pick up the gun, ammo, and medkits on Sechenov's desk. You can also use the computer here. Approach the elevator shaft, which you used to reach the upper floors in the main game, and then watch the cutscene.

Along the way, you will encounter broken Vovchiks. A few shots are enough to deal with them, especially since below you will find a new melee weapon "Thunderer". This hammer can deal damage to enemies several meters away from the protagonist if you use the alternative attack with the right mouse button. But remember that such attacks consume Nechaev's energy.

Once outside, in addition to broken enemies, you'll encounter fully functional models. Their attacks are similar to those in the main game, but they will often use flagpoles as weapons.

Near the stairs in front of the building lies a dead deputy — you can interact with him for the collection. Also, check the table behind the car on the left side of the location, where you'll find the chirper "Percy Bysshe Shelley". There's nothing more on this map, you can approach the gates and use the whip (Q key) to cross the fire.

In the next area, also deal with several Vovchiks and explore the area. Besides two supply chests, you'll find a dead agronomist and the chirper "Pulling Chestnuts from the Fire" on a nearby bench.

Upon reaching the improvised arena, you will encounter a previously unseen opponent — a giant iron doll. This enemy is very fast and deals quite a lot of damage even on medium difficulty.

The battle can be divided into several stages. In the first stage, you need to dodge the robodoll's attacks and sudden lunges in time. This is easiest to do with the help of the flying bee robots hovering above the arena. Use the Q key to grab if you notice the enemy is about to attack, having previously aimed the camera at the bee.

Along with this, we recommend shooting the enemy with a pistol, as melee attacks will be almost useless. Once the robot's engine overheats, to avoid wasting time, use the whip to reach the boss, then deliver several strong melee weapon hits. Alternatively, you can shoot the engine from afar.

Then comes the second stage of the battle. The boss climbs to an elevation and shoots at the hero with explosive bombs. Dodge the attacks and wait for the engine to overheat again, then shoot it with a pistol.

In the third stage of the battle, players face combined attacks from the boss: he will resort to scattering bombs and add another type of attack — a laser. Cars will appear in the arena. Use them as a shield, as avoiding the laser is almost impossible.

Soon all stages will repeat again. You just need to follow the developed tactics and destroy the enemy.

Cross to the other side of the collapse using the bee and enter the building. After a short cutscene, inspect the chest, find the chirper "Complaint About the Rain", and you can read the notes on the computer. In the box, you will find a reinforced head for the Thunderer.

You won't be able to use the repair box now. Inspect the room for useful items and open the door outside. This is the second type of lock you might have encountered during the main game's playthrough.

Outside, several Vovchiks and a couple of chests will be waiting. When you pass between the houses, turn left. There will be a corpse of a local barker and a chirper "Tomorrow Was the War".

Approach the Bumblebee and interact with the hole in its body, having prepared for the robot attack. There will be several waves, after which you need to try to connect to it. On the third attempt, the major will finally manage to do it, and you will find yourself in another location.

Listen to the dialogue of the heroes and inspect the shore. Underwater, you can find a hidden supply crate, and under the rocks, a chirper "Haven't Read, but Condemn".

Continue following from marker to marker. As soon as Blesna finishes the monologue, you will gain a new ability. With its help, you can get rid of polymer growths to unblock the path. Such an opportunity will present itself now.

Climb the rock using the whip and inspect the contents of the chest. In the passage in front of you, you can go down and loot another crate. The opponents in this location will be kultyshis — zombie plants controlling human corpses. We advise not to waste ammunition on them and to destroy them using melee weapons and Nechaev's abilities.

Reach the robot Terenty and have a conversation with it. Climb a little higher and burn the polymer growth to enter a small enclosed area with a yellow chest. Return back and use the whip to overcome the ravine.

If you climb to the highest part of the rock, where there are boxes with yellow devices that the main character can grab with the whip, find a supply crate. It will contain an upgrade for the Thunderer — a enhanced handle.

Near the only building, there is a computer with records, as well as a corpse of a dead rescuer, with whose consciousness you can converse. Climbing further up the path, immediately turn left. On the middle table, there will be a chirper "Thursday — Crab Day".

On the veranda, you will find a corpse with which you can converse, as well as another computer with records. When you're ready, head to Baba Zina's hut and get rid of all the zombies, then climb up to her and watch the cutscene.

This way, you will receive the first powerful firearm in this DLC. The shotgun can not only shoot regular charges but also has an alternative shot. Use the right mouse button to release a charge and spend the major's energy.

There will be about two dozen enemies in the arena, as with any major battle in Atomic Heart. Deal with them all and return to Zinaida Petrovna.

Soon Baba Zina will throw you out of her flying apparatus. Descend the stairs and use the elevator. You will find yourself in an underwater complex. Talk to the dolphin, who will ask you to find a power source (candle). But first, we recommend exploring all available rooms, destroying enemies, and collecting useful items.

When you're ready, return to the main hall and use the whip to climb to the upper level. There is a yellow chest with a shotgun upgrade — enhanced stabilizer.

Jump to the top of the dome and take the candle from there. After inserting it, the gates should theoretically open, but first, the dolphin will ask you to answer a question: "How many continents on planet Earth have names starting with the letter 'A'?" The correct answer is five continents (Africa, two Americas, Australia, Antarctica).

As soon as you approach the gates and try to proceed, they will close again, and several robots will attack the hero. Deal with them, inspect the supply crates, and continue along the only path.

The marker indicates that you need to go straight, but you can explore the branches, find several enemies, and a couple of chests.

As soon as the bridge collapses, the main character will find himself underwater. There is nothing valuable in the large hall — swim to the adjacent room. Here, inspect the drawers and chest using the glove, then find the hole next to the crate through which you can crawl.

Move through the ventilation shaft following the arrows, but when you descend lower, the arrow will point to the right — turn left to enter a secret room with a yellow chest. Inside will be a shotgun upgrade: circular barrel. We recommend using it in the future, as the shotgun will deal massive damage and knock back small enemies a considerable distance.

You can return the same way or by climbing into the higher hole. In any case, you will find yourself back in the same ventilation shaft. You will be under the platform in the first hall. Take the contents of the chest and interact with the valve. The platform will rise from the water, and you will be able to open the passage using the control panel.

Here, several new monsters will appear before you. They deal minor damage and are generally not dangerous. The main thing is to keep them at a distance. In the entire next segment, gamers must find and activate valves, raising the water level in the complex.

When you reach the room with the pool, collect the contents of the crate underwater, and also climb the ladder to find a yellow chest. Inside is a enhanced magazine for the shotgun.

In the adjacent room, there is also a supply crate, as well as a rest room. When you're ready, proceed to the only open hall. Here you'll encounter another new type of monsters — crabs. Their shells are quite sturdy, so there's no point in shooting at them or using melee weapons. Wait for the enemy to expose a vulnerable spot, then shoot at the belly. Also, the monsters are effectively eliminated by the explosion of Nechaev's new ability.

After dealing with everyone, use the whip to pull yourself up onto the platform leading to the control panel. To the left of the entrance is a crate, and in the next room, a new opponent will be waiting, emerging from ventilation holes. It releases many ink sacs that deal damage when approaching the hero. Try to destroy the enemy as quickly as possible, but it will attempt to hide after a few hits and may emerge from another hole.

Pull yourself up with the help of bees to the platform above and interact with the second button to open the sluice in the center of the hall. There is also a rest room here.

Wait for the lifting mechanism to lower the hook for grabbing, latch onto it, and then immediately grab the hook on the wall with the whip to fall onto the metal platform. After that, latch onto the hook on the lifting mechanism when it rises up.

As soon as you reach the top of the structure, a dialogue between the heroes will begin, which cannot be skipped. Listen to Blesna and inspect the chest on this platform, then find the ladder leading up — here is another crate with a shotgun upgrade (horizontal barrel).

Dive underwater, but do not swim towards the marker. Find the ladder leading up on the opposite side, where there is a supply chest. Once you've done that, swim towards the marker. This will lead you to the depot.

Immediately deal with several large robots and solve a simple puzzle with the cistern. Interact with the control panel: press the "Down" button, then "Rotate Platform," and finally "Up." The cistern will rise to the upper level, and you will be able to use the whip on the hooks located on the cistern itself to climb up. Use the skill to burn the polymer growth blocking the passage.

In front of you is a railway section, more reminiscent of metro tunnels. You can only move along the tracks, where trains pass at intervals. The floor between them is electrified, so it's not advisable to descend — even on medium difficulty, the hero will perish in an instant.

Get rid of the polymer growth and move to another platform. If you see that you won't make it to a safe spot in time, use the whip again to avoid collision with the train. We recommend not rushing, as you are not limited by time.

About halfway through, in the safe zone on the left, there will be a corpse of an electrician, with whose consciousness you can interact. Next to him is a yellow crate.

Note: as soon as you reach the next safe zone, an octopus will appear from the ventilation hole on the right.

At the station, there will be another supply crate and a rest room.

Inspect the restroom, where one enemy awaits, then climb the first ladder. To the right will be a room with a crate, and further up, several more ladders. Along the way, you can inspect two regular chests, open the passage, and find yourself in office spaces. In the first room, there is a corpse of an actress — talk to it and read the notes on the computer in the adjacent room.

Climb to the second floor. In the hall, on the table, there is a Chirper "Confusion", as well as several drawers and one supply crate.

Head to the only open hall in this area to fight a new mini-boss. Unlike main bosses, this opponent does not have a health bar, as it is considered a regular enemy.

We recommend not wasting ammunition and using the whip, constantly dodging the arthropod's attacks. Wait for it to expose its vulnerable spot on the belly, glowing orange, then shoot it with firearms.

After defeating the enemy, run to the only open door and talk to the corpse of the killed technician. There is also a rest room and several crates here. As soon as you move to the next hall, the task will update.

Get rid of the robots and approach the breach in the wall, behind which a pipe is visible. Use the hook, then throw a flare over the wall to ignite the gas. Behind the opened door, you can pick up supplies and the Chirper "Chichikov's Case" on the table. Take the energy element and insert it into the device next to the button to open the grate.

Find the blocked entrance to the cafeteria, use explosives to remove the obstacle. In this room, you can gather condensed milk and find a locked passage to the kitchen. Remember it, we will return here later. For now, head to the hall with the huge whale and press the red button.

After this, mutants will start appearing on the improvised arena, and the wires connected to the whale will begin to emit electricity. Note: before the next strike, you will hear a characteristic sound. Immediately after this, you need to grab one of the dolphins hanging from the ceiling, or you will take serious damage.

It is not necessary to kill all the enemies, it is enough to hold out for a certain time, after which the monsters will stop appearing, and the whale will cease attacking with electricity.

Most of the wall in the far corner will collapse, opening a passage for the hero. Climb into the ventilation shaft, stop the blade rotation using the electric ability, and jump off the other side. A lengthy cutscene will begin, during which you will meet the technician Nikolai.

Take the key from the technician. Descend into the shaft via the pipe and unlock the door to the hall with the whale from the other side. Don't forget to look around. There are several crates and a rest room here. Remember the locked passage to the cafeteria kitchen? Interact with the lock so the hero automatically inserts the found key and opens the door. Besides the chest, take the repair module from the shelf on the right.

When the fire is extinguished, descend the broken staircase to the very bottom to find a crate. Then use the hooks to climb up one level and exit into the reception area. First, head to the restroom and find the Chirper "Important Information" and a chest. Be warned that a large robot will appear at this moment.

Burn the growth at the entrance to the zoology section and inspect the locked door, for which you will also need to find a key. To the right of it on the ceiling is a similar growth blocking the passage. Get rid of it and jump down to the other side, where several mannequins await. On the bloodstained table, take the cookie key and return to the door.

Further in the room, you will notice an octopus climbing into the ventilation shaft. Don't rush to follow it — first, search the premises and find several crates, as well as a computer with records. When you're ready, tear off the ventilation grate and climb inside.

Get rid of a few Vovchiks and inspect the box with the image of a ballerina, in the room next door you can read notes on the computer. To continue, look at the blocked passage from the balcony and burn the growth.

Take the contents of two crates near the collapsed bridge, and when you return, enemies will come out of the door on the right. Kill them and inspect the room. On the upper level, there is a Chirper "Dante" on the table.

If you go down, you can talk to the deceased whale researcher. On the table in front of him lies a sheet with an image — this is the graphic key that will fit the door on the upper level.

Reaching another locked door, look up and use the hook. Use the valve to move the cistern to the right, then find the button on the balcony and press it. Wait for the filled cistern to arrive and return to the shower to undergo decontamination. Beforehand, don't forget to go down under the platform and find the hidden crate with supplies.

Deal with the robots and interact with the door behind which two strangers are arguing. A lengthy cutscene will start, after which the task will change.

As soon as control passes to you, pick up the Chirper "Passion" on the couch. Take one of the red balls from the drawer. Use this item to guide the dolphin to the door so it can open it. First, lead the dolphin to the aquarium without water, place the ball on the ground, and interact with the valve.

The tunnel will fill with water. Once the dolphin swims further, turn the same valve again, and then interact with the second one. The water in the previous aquarium will move to the next one.

In the next hall, you will meet a dolphin named Lola, who asks you to rid her of the dirt in the aquarium. However, you won't have to clean it: find an empty aquarium, move it to the pipe, and fill it with water, then move it to Lola's aquarium. The dolphin will jump into it, simultaneously opening the passage for the main character.

Proceed through the lounge to the performance hall. Along the way, collect all useful items and craft ammunition if necessary, as you will face a serious battle with a large number of enemies. In the room with chests, you can also find a second box with the image of a ballerina.

Truthfully, the next battle will not differ much from the previous ones in this add-on, except for the number and variety of opponents. Use hooks and a whip to dodge attacks and destroy everyone in the arena.

After the conversation with Baba Zina, jump into the only open hatch leading to the flooded parts of the complex and swim through the ventilation. In the engine room, take the contents of several crates and press the red button next to the gates. The task will update.

Once at the bottom of the lake, you will see a small cutscene, after which it will become clear that the hero should avoid the spotlights. Use jellyfish and other objects to pull yourself with the whip and move faster underwater.

The entrance to Block "B" is guarded by combat robots. Climb into the capsule near the entrance and inspect the computer. The power is missing, and you'll have to restore it. Swim in the opposite direction and inspect the locked cave entrance. If you use the scanner, you can find a valve nearby. Activate it, climb into another capsule, and disable the protection.

In the cave, you will find not only a power block but also a chest and a dead debugger's body. You can choose to talk to it before leaving. Insert the candle into the module and supply power to the spotlight. Soon, a huge mechanical creature will open a passage for you.

Climb into Block "B" and activate the second part of the bridge. Run towards the marker in the assembly shop, destroying monsters and robots along the way. Soon, you will find yourself near Eleanor's repair cabinet, who will ask you to find a power module to activate another repair cabinet, the purpose of which we will learn later.

After talking with Eleanor, go straight and turn into the passage on the right, where a robot will be rolling out Catherine's mechanical body. Deal with the mannequins, then inspect the office rooms on the second floor. On one of the tables lies a Chirper "Kuzmich's Pearls".

Pick up the candle and insert it into the device next to the door to the biological laboratories section. Dive underwater, swim through the flooded sections of the complex, where you will find the second power module. Once you take it, the gates will open, and you can return to your friends on the bridge.

Talk to the technician, activate the Samodelkin repair cabinet, and climb inside it. Before leaving, you can ask the robot a few questions. Get in the capsule and head to the city of dolphins, where gamers will face the final battle.

Near the lounge, there is a blocked passage to an office room where you can talk to a deceased dolphin. In the central hall, open the primitive lock and find a dolphin named Nekit. He will receive coordinates from the ichthyologist but will get off track. Take the red ball again and guide him through the tunnel, first removing the growth so the dolphin can jump into the aquarium. Aside from the supply chests, you won't find any valuable items along the way.

Once you reach the safe room, prepare for the battle with the final opponent. As soon as you reach the main gates, a cutscene will begin, after which you will find yourself in an improvised arena.

This opponent seemed easier to us than all the previous bosses in Atomic Heart. In the first phase of the battle, Murena uses several sharp lunges, which are very easy to dodge using the whip and the hooks on the chandeliers. Dealing damage to the enemy is a pleasure, as orange spheres appear on its body that need to be shot in time. With each hit, the enemy loses about 15% of its maximum health.

When the enemy falls, look around and make sure you are not standing in the area affected by the tiles that are about to fall from the ceiling. You will have to run on these tiles in the second phase of the battle, as the rest of the floor will be electrified.

Continue dodging attacks and dealing damage with firearms. When the enemy runs out of health, watch the long video that concludes the story add-on for Atomic Heart.
