How to complete Testing Grounds 2 in Atomic Heart
You will need to find a device to hack into security cameras to open the door to Polygon Testing Grounds 2. We have marked the location of the device and Testing Grounds 2 in the image below. Use this to make your way into the testing grounds.
When you come out of the elevator, you can loot the room to the right but will need to take a left to progress further. Go through the doorway and defeat the enemies there. The next room will contain a rotating diagram and magnets.
Rotate the first wheel once to spin objects on the stationary diagram. Then Shok the magnets to move the wall. Wait for the rotating diagram to have an opening, the red or yellow wall, and make your way across. Rotate the wheel across the way three times so that the green cabinet is on top. Go through the opening.
Turn right to find the first chest and receive the MP-Electromagnetic Polarizer. Exit the room and press the red button to remove the lasers. Enter the room and go left and downstairs to gather loot. To the right will lead you deeper into the facility. Drop down into the chamber with the magnets.
Go to the center wall that has yellow handholds. Shok the ceiling magnets and quickly grab the handholds. Climb to the right and jump to the next set of handholds. Climb to the left and jump to the red platform. Shok the ceiling and jump to the red platform with handholds.
Jump to the red platform diagonally to your left. Shok the magnets directly above you. Jump to the yellow handholds on the left wall and climb across. Jump to the blue platform in front of you and Shok the magnets. Jump to the handholds on the wall and go left to the red platform.
Jump on the platform in the corner and Shok the blue magnets above you. Climb onto the red platform rising in front of you. Climb up the yellow wall and stand on the horizontal magnet wall. Shok the magnets attached to this wall and climb into the tunnel.
Drop out of the tunnel and go to the right to find the next chest. Open it to receive the KS-23 Supersonic Vibrator. Turn around, Shok the magnets, and go through the hallway. Enter the next room and prepare for another puzzle.
Make your way to the gray platform, not the magnet one. Jump to the magnet wall and Shok the magnets on the ceiling. Jump onto the blue platform in the corner and Shok the ceiling. Climb onto the red platform. Jump across to the blue platform in front of you.
Climb onto the magnet wall. You will need to Shok the ceiling and then quickly jump as the platform lowers across to the blue platform behind the gate. Drop into the cage and go through the door. Turn right to find the last chest and the Kalash-Thermal Scope and Snowball-Blade. Take the elevator and get out of Testing Grounds 2.
