Atomic Heart Full Walkthrough and All Endings


At the beginning of the game, choose the difficulty level. After the cut-scene, move along the marker. There is nothing complicated in the prologue.

The Complex

Having got to the Enterprise 3826 and picking up an ax, go along the marker and kill the enemies. Open the toilet cubicle and watch the cut-scene.

What The Fuck Have I Gotten Myself into?

Approach the door – you need a valve. Turn around and climb up the boxes. Find the valve and the first device. If you collect all the devices, you will get an achievement (read in separate guides). Go back and open the door with a valve.

Wanted Dead or Leave: Viktor Petrov

Let’s go ahead. You can save in the room on the right. Kill the first enemy using the prompts on the screen. Search the premises. Press F to collect all resources. Kill enemies in the corridor and examine the door on the right. You need to unlock the “Shock” skill.

One More Hurdle

Pass through the door at the very end and watch the video. Dodge to the side when the black laboratory assistant will shoot at us from the laser. Attack him, dodge, repeat. Don’t forget have a shotgun.

Wanted Dead or Leave: Viktor Petrov (continued)

Break the first lock. Click with your finger to push all the elements. After each click, the light bulb will change direction (clockwise or counterclockwise). You need to push all the elements. With each retracted element, the light bulb will move faster. Go ahead and study the Eleanor machine gun. Here you can craft, improve weapons, unlock skills. Get the “Shock” needed to open that very door. Go out into the corridor, the elevators are de-energized.

Not so Fast, Major

Pass through another door and inspect the castle. You need a special key. Go back and go up. Destroy enemies. Surveillance cameras will appear on the walls. They can be disabled with Shock or simply destroyed with a weapon. Find the key in on the table the room on the left. Go back and open the door.

Interact with any piece of the puzzle on the wall on the left. Rotate the elements so that the blue beam falls on the blue lamp, and the red beam falls on the red ones. The lasers themselves are on the right. See screenshot below:

Use any elevator. Shoot the Shock at the batteries above the door the marker points to.

Wanted Dead or Leave: Viktor Petrov (continued)

Clean the corridor and move past the trolleys. Jump into the polymer substance and swim in the other direction. Look at the castle. You need a graphic key. Open the huge door by shocking the batteries from above. Move along the left wall and find a piece of paper with a key. Return and enter the code on the lock. Launch the funicular and sit in it.

Kill the enemies and jump onto the yellow bar on the wall to the left. From it jump to the right and so on to get around the pit. We are not in a hurry, so as not to die because of a huge worm. Make our way into the last hole on the left. There is a corpse in the room. You can communicate with these corpses, and if you talk to each one, you will get an achievement. Climb into the hole in the wall on the upper right and climb to the end.

Jump into the tunnel, go around the funiculars and go to the station. Save and exit through the door on the left. Follow the marker, use the vending machine to unlock a new skill. Leao (Shift) pass through the lasers. Go down and watch the video.

In Hot Pursuit

Destroy all enemies and look around. Open the door, you need a special item. Go down and climb the stairs on the other side. Find a hole in the wall in the room and climb through the ventilation into the next room. Immediately break open the lock on the left. There is Makarov pistol on the floor. Take a candle and carry it to the door. When you approach the slot, the candle will automatically be installed in it.

Move past the loaders. When the loader lifts the boxes, pass under them. Go down and find the polymer on the left side. Jump into it and move through the polymer to the other side. Behind the rack opposite will be the enemy. Immediately kill him and select a capsule with lunar soil. Find a room with a puzzle in the far part of this hall with shelves. You need to install three capsules with lunar soil. There is one at the beginning of the hall.

Having installed the first capsule, pass into the polymer from the side. In another part of the room, the Electro drawing is unlocked. Energy weapons, unlike conventional ones, do not require certain ammunition. You need energy that accumulates when using the rest of the weapon. Take the second capsule with lunar soil from the vending machine and climb through the ventilation in the wall. In the ventilation you find the third capsule with lunar soil. Go back, moving further along the ventilation, and install all the capsules.

Go to the warehouse. Kill enemies and move the only route. Go up the elevator, move to the marker. Jump over to the building in front and with the help of a cable go down to the desired polymer. If you fall down, just have to break open the right door.

How to break open doors with colored dots

Everything is very simple – three slots from the bottom can be swapped. Move the colored points there and change their positions until the points, when rotated, coincide with the same colors on the elements in a circle. If it doesn’t work, move away from the door and interact again – the puzzle will change.

Go down through the polymer and go to the corner where you find the corpse of Petrov. Be sure to take a candle. Break open the door (the candle can be left in place for a while) and return to the common room. Install two candles on the columns in the center of the hall. You found one candle at the corpse of Petrov, the other must be pulled out of the cell by the door, where you parted ways with Petrov in the cut-scene.

In an Overgrown Park…

To get out of the Vavilov complex, you will have to find four flasks in different workshops. Wait a bit for the door to open. Pass through it. Flasks in this wing can be taken in any order. Move along the corridor to the right, to the Hot Workshop.

They want to make a green Mars

Climb the stairs, go through the hole in the wall and go down the flights of stairs. Kill enemies and inspect the room.

Into the Fire

Three boilers need to be cooled down. On the right there is a container with blue spheres. Take one and take it to the receiving device in the next room. Return to the hall with hot boilers. Use the F key to move the sphere over the glass tubes. Cool any cauldron, then repeat this with all 3 cauldrons. Enemies will spawn between each successful cooldown.

Rise along the stairs, go along the marker into the hall. Use the pallet on the cargo lift to get to the flask with heat-resistant polymer. In the center you rise along the inclined panel and jump into the pipe. Install the flask in place.

Chronos Trigger

Go to Algae Workshop. Move along the marker and kill new enemies. Open the doors by pressing the red buttons. Clean the long corridor and solve the puzzle. Rise up in a huge hall and take the capsule. Jump over to the other side (Shift to dash in the air) and install the capsule. Having done this, rise to the control panel through the polymer. Launch the platform with the red button. Driving past the controls, charge them with Shock (V key). Flying drones will gradually appear. Destroy them.

Restart. Jump over to the platform on the right (when yours stops). Kill two enemies and solve the puzzle on the wall.

Continue to move. When all the elements are charged, go down and wait.

Everything Illuminated. Take the flask and take it to the right place.

Pass through another red door into the right wing from the hall with the Birch. There is only one way to go, to the right. Move aside with the help of telekinesis (key F) the shutters. You find ventilation in the back room. Clean the room from monsters and move through another ventilation. In the hall with animals, turn the valves so that they are all turned clockwise. If you turned the valve counterclockwise (to the left) during the interaction, then interact with it again. All animals must die.

March of Flowers

Before doing anything, we recommend clearing the entire hall from enemies (plants). Climb up and solve the wall puzzle.

After that, press the red button. While the flask is filling, just kill the enemies. In which case, start the valves on the ceiling with “Shock”. Pick up the flask and move along the marker. Go down the pipe, kill the enemies in the corridor. After opening the door, watch the cut-scene.

As You Sow, so Shall You Reap

Go forward and to the left. For now, move along the marker until you see a large yellow can on a flatcar. Go up next to the yellow tank, up the stairs. Jump onto a rotating wagon with plants, from it – onto a visor above the aisle. From there jump to the bridge near the wall, where there is a plant that lets enemies in. Jump on the platforms to the control panel near the suspended wagon with plants. First, press the big round button to rotate the platform.

Press the up arrow to move the car forward. Jump back and to the left. The platform under you will probably collapse, but pay attention to the wall – you can climb the yellow beams. Turn the platform and move the wagon with the yellow tank to the right. Jump to the other side, go along the corridor and get along the rotating car to another console. Turn the platform using the remote control and push the car forward. Return to the previous hall and use the other console to push the car further. In general, everything is simple here – you need to return the car back. Let’s watch the video. Last flask received! Kill enemies and return back.

Follow to the indicated place. The gate will be locked. Use the Shuttlecock (Volan) on the left, switch to the camera and open the room near the water, at the end of the pier. Use this room to lower the flying device “Griff”. Run to the “Griff” and cling to the yellow pipe. Slide down the rope. Defeat the Hedgehog. You can raise columns from underground (with remotes) and force the Hedgehog to crash into them (deals damage). To avoid flying projectiles, stand still and just look at the Hedgehog. After the shot, we dodge with a jerk to the side.

Go down, move the right mirror to the right with telekinesis (F key). You are trying to move the left, but something is stuck.
