Upgrading your gear is always a good idea unless you’re one of those masochists that like to do starting weapon runs in video games. You don’t want to go through the whole game without a single upgrade to make your more optimal!
That’s why it’s great to find these upgrades as soon as possible.
In Atomic Heart you can find different weapon upgrades in the big open-world area of the map and in this guide we’ll show you where to find all the upgrades in Polygon 1!
Atomic Heart: Polygon 1 All Upgrades
When you get to the open-world section of Atomic Heart you’ll notice that there are a lot of Polygons or Testing Grounds scattered around the map.
These Testing grounds often have multiple loot chests in them so it’s good to know where to find them and how to get to them. Especially since all of them have upgrades for your weapons!
This is where you can find all the upgrades in Polygon 1!
To start getting all the upgrades you first need to get inside Polygon 1, that’s where you go to the node that lets you see through all the cameras in the area.
Once you get there you’ll need to select the camera shown below.
With the camera, you’ll need to look to the left and use the button on the building with the blue roof.
This will open the door to it and you can go inside and go down the elevator there to Polygon 1. Once you’re down there head right and you’ll enter the first puzzle room.
The first puzzle is simple, you’ll see a short wall that you can stand up on, once there look directly up and use Shok on the magnets in the ceiling.
This will raise the wall and with it, you can then use Shok on the other set of magnets shown below to lower the wall in front of you, you can then go through the door and onto the next puzzle.
The next puzzle is even simpler, just step on the blue magnets shown below and Shok the ceiling, you can then jump dash to the door in front of you.
Once through the door go straight and then right to another door and then left until you find a ventilation shaft you can crawl up to shown below.
Once inside go straight then right, then left to go down a hole, then left again to go to a hallway.
The second door to the left has your first upgrade, an upgrade for Fox’s handle.
Now go out of the loot room, turn right then left until you see the large room with the red tubes.
Go to the very back and turn left, then right and up into a hole in the wall.
Go straight to the door open door at the other side of the room and you’ll see a line of magnets you can Shok to clear the way. Go forward through another door and to the right is another chest with another upgrade, this time for the PM!
Now go back to the magnets and Shok them again to move the wall back to the original position, then go to the right then right through a door to another puzzle room.
Shok the magnets above again and then make your way to the back of the room and to the left, on top of a red platform is a puzzle.
Below is the sequence of interactions you need to solve it.
Now at the back of the puzzle wall is a blue platform, get on top of it and Shok the ceiling. This will raise you up and you can go through the now-open door.
Follow the path until you see a room to the left, go inside and you’ll see the last chest that has the last upgrade, the KS-23 Extended Magazine!
Congratulations you now know to get this upgrade in Atomic Heart, now go out there and try to do it yourself!
