Atomic Heart Skill Trees [All 7 Explained] 

With the amount of skills showcased in Atomic Heart here, it is sure to win your heart!

With the Atomic Heart Skill Trees being so complex, it can become a bit tedious to figure out what skills and upgrades are. Therefore, players might require assistance figuring it out! 

IMPORTANT: You can create a custom-build of your character by selecting various skills from 7 skill trees called Shok, Character, Frostbite, Mass Telekinesis, Polymeric Jet, Polymeric Shield, and Energy Management.

Key Takeaways
  • Players use Neuropolymers in order to buy upgrades or buffs to enhance their base skills. 
  • The hexagon-shaped nodes are the ones that players need to install before they are able to make use of it in and use it in combat. 
  • The square nodes are there to help players gain passive buffs that further enhance the existing hexagon skill. 
  • After players buy the upgrades, they do not need to install them in order to use them; rather, it’s automatically embedded. 
  • Players can only have 2 active skills at any given time, which means that players need to swap out skills here and there. 
  • The main benefit of knowing all the skills and upgrades is that it gives the players a chance to figure out which ones they want to invest in!

Skill Trees Explained

Energy ManagementPassive buffs for energy generation, power consumption, and recycling.

Kicking things off, let’s consider and explain in detail what exactly the Atomic Heart Skill Trees are in this game. 

In the know, there are currently 7 skill trees in the game that are represented towards the left side of the screen. Players can access these skill trees by heading toward the giant red machine and interacting with it, which goes further in-depth. Computer 1 asks you to select the desired procedure and offers you three options: 

  • Weapons. 
  • Charles needs a tune-up 
  • Leave 

After booting the system, it splits into its respective skill trees in Atomic Heart.

There are a total of 7 skill trees, which are as follows: 

  • Shok 
  • Character
  • Frostbite 
  • Mass Telekinesis 
  • Polymeric Jet
  • Polymeric Shield 
  • Energy Management. 

How Do Skills Work 

In Atomic Heart, whenever you open your specific skill tree, such as Frostbite, you can see two types of shapes enlisted for the player. 

  • The hexagon-shaped “skill” is the skill you need to install before you can use it freely. This means that players cannot use the skill before they can install it, and then they can use it against opponents whenever they are in heated combat. 
  • As for the square nodes, those are essentially upgrades that can be attached to the pre-existing installed skills, or they can also be described as simply buffs that make the skill all the stronger. 

Taking Frostbite as an example, we have the cryo-jet as the “base skill” that players need to install to slot it into their skill slots, and then they can use it freely. 

  • The cryo-jet skill is displayed towards the bottom of the “tree,” starting from there, all of the square nodes represent their own upgrades or buffs, which essentially strengthen the actual base skill. 

How Many Skills Can Be Used 

Essentially, whenever players open their skill trees and skill screen, they can see on the bottom of the screen “skills in use.” As such, players can only have 2 active skills at any given time, and players need to swap skills that are no longer needed so that they can swap in the ones they can use.

Shok 

Starting things off, let’s look at the first skill tree, the Shok. It is one of the first skill trees that features primarily only Passive buffs/upgrades that players can use. It has 10 passive buffs that players can acquire, and they are listed as follows. 

Powerful Electrization 

Powerful Electrization

One of the first ones we have on the list is Powerful Electrization, and players need to spend a total of 87 neuropolymer to buy it, after which they don’t need to install it; rather, it can be used automatically. 

  • With the buff in hand, any repeated attacks that are carried out against enemies can apply an extra Electrifiec effect to enemies. If enemies are Polymerized and have low HP, they are broken to pieces. 

Neuro-Polymer Accelerator

The second one is known as Neuro-Polymer Accelerator. With it, players can have their overall SHOK cooldown decreased by a little bit, costing 75 neuropolymer to buy. 

Resistor Malfunction

Moving on, when it comes to the next buff, we have Power Amplifier, which costs back players 40 neuropolymer, making it out to be a bit of a cheap end. 

  • Whenever it has been activated, players can deal enhanced damage to opponents surrounding them with their SHOK, and it also causes enemies to be pushed back, with which you can carry out even more attacks. 

Electrization

As for the next passive, players can use Electrization to cause opponents to become electrified with their SHOK, which makes them all the weaker so that players can easily take them down even more easily. 

Shok

As far as SHOK is concerned, players can use their gloves to take out an electromagnetic discharge toward opponents that continues to target them further, and it can deal even more electric damage to enemies that are present in front of them. Typically robotic targets can take in even more electric damage since they are highly vulnerable to electricity. 

Amplified Modulator
