In Atomic Heart, you will need to unlock testing grounds in order to progress in the game. In this guide, we will take you through how to get the Atomic Heart testing ground 11 key.

Getting weapon upgrades in Atomic Heart Testing Grounds 11 can be challenging. This is because you need to locate a key to unlock the initial door.

The key’s location isn’t obvious in the open world, but that’s what we’re here for. Let’s find out where the Atomic Heart testing ground 11 key is!

Where to find Atomic Heart testing ground 11 key

Atomic Heart offers players an expansive open world to explore for hours, with specialized testing facilities full of arsenal upgrades scattered between mission areas. Testing Grounds 11 is near the massive bridge leading to the Infirmary building. You’ll encounter this area after completing the Theatre level.

To find the key, you will need to enter a small walled-off compound directly northwest of Testing Grounds 11. The walls surrounding the compound are too high to climb directly, so there are two different ways to enter. Here’s the easier of the two ways: climb on top of one of the trains, head close to the wall, and jump directly into the compound. The other route involves lowering the nearby Hawk for maintenance and using the zip line to enter the compound directly.

Upon entering the compound, you’ll find a large main building with a spiral staircase at the top and a much smaller building in the southern part of the compound, near a door with a lock on it. Once inside this smaller building, you’ll need to pick the lock and defeat the enemy inside. The key can then be found next to a dead body. After acquiring the key, exit the compound and return to the Testing Grounds 11 building to enter it and take the elevator down.
