The Testing Grounds are getting stranger and harder to find in Atomic Heart. Located at the Computational Center at the top of the hill in the center of the map, you’ll have to locate multiple camera relays and hack three hidden switches to unlock the doors to this dungeon. The dungeon itself is strange too — a vast complex with cyclopean-sized rooms, forcing you to platform and fight to claim your rewards. Let’s talk about how to complete Testing Ground 8 and grab awesome upgrades like the Revolver Barrel for your MP handgun.

Testing Ground 8 is located high up on the hill at the Computational Center. You’ll visit this area while searching for Petrov. Inside the lobby, there’s a mysterious elevator with red lights. You’ll need to find and activate hidden switches around the region to unlock the door. The switches can only be activated from cameras.
Activate all three switches and the elevator to the testing ground will open. Very tricky! Down below, you’ll encounter more classic test rooms.
The bronze reward chest is just around the corner. Don’t go down the stairs just yet.
Take the stairs down to the Safe Room and then cross the underground tunnel to the giant hydraulics testing chamber. You’ll be ambushed by drones and rolling turrets — nothing too difficult.

Ahead, you’ll reach a gigantic submarine bay.
