Atomic Heart Testing Ground 10 Complete Puzzle Walkthrough And Rewards

Exploring the dystopian environments of Facility 3826 in Atomic Heart often leads players to hidden underground bunkers known as Testing Grounds. Testing Ground 10 is an optional subterranean laboratory that challenges players with environmental hurdles and rewards them with highly valuable weapon upgrades. Successfully navigating this particular dungeon requires a solid grasp of Shok magic, magnetic manipulation, and precise combat coordination.
Gaining Entry to the Secret Facility
Locating the entrance to Testing Ground 10 requires traveling to the rural farmlands situated near the large wind turbines. Players must find a nearby log cabin and ascend its roof to access a camera system terminal to unlock the bunker doors. Interacting with the terminal allows you to activate a sensor on a small elevator house nearby, which grants access to the facility below.
Some players have experienced minor collision issues when attempting to step into the bunker elevator. If the mechanism appears unresponsive, simply pressing your character directly against the wooden frame should trigger the sensor. Descending into the facility introduces you to the first set of complex puzzles requiring careful analysis.
Navigating the Magnetic Core Chambers
The initial chamber presents a massive wall puzzle powered entirely by magnetic physics blocks that change position based on electrical current. Using your Shok ability on the ceiling generators will shift the floor panels, allowing you to create a traversable path to the far ledge. You will need to bring an explosive power sphere into the second room to unlock the exit gate.
Once inside the secondary puzzle room, players will notice a locked door that requires two separate power spheres to activate simultaneously. Finding the second sphere requires manipulating the overhead magnets to drop a hidden container from the ceiling structure. Gathering both items allows you to open the pathway leading directly to the mid-tier supply containers.
Surviving the Subterranean Combat Trial
After collecting the initial loot drops, you will enter a flooded industrial sector filled with aggressive mutant variants and specialized robotic sentries. This enclosed arena forces you to manage crowd control effectively while utilizing your surrounding environment for cover. Prioritizing the organic spawners first ensures you will not be completely overwhelmed by endless waves of enemies.
Clearing out the hostiles allows you to safely inspect the room for hidden upgrades and additional crafting components. Before leaving the combat zone, ensure you interact with the local save station to preserve your current progress. The final hallway requires one last application of your Polymer Jet and Shok abilities to clear the exit doorway.
Claiming the Specialized Weapon Blueprints
Completing all three sections of Testing Ground 10 rewards players with unique Lootyagin chests containing critical modifications. The bronze container yields an extended magazine blueprint for the Kalash rifle, significantly boosting your overall ammunition capacity. Proceeding further into the silver chest unlocks a unique upgrade for the powerful Dominator energy weapon.
The final gold container provides a devastating combat blade attachment for the Zvezdochka melee weapon, making late-game encounters much easier. Collecting these blueprints contributes directly to the overall completion trophies associated with exploring the facility networks. Upgrading your gear at a nearby NORA station allows you to immediately test out your newly acquired combat capabilities.
